Fig. 2 is a flow chart of a method of controlling a photovoltaic cell according to an embodiment of the application. As shown in fig. 2, the method comprises the steps of:

step S201, current illumination data of a photovoltaic cell is obtained, wherein the illumination data at least comprise illumination intensity received by the photovoltaic cell at present, environment temperature of the photovoltaic cell at present and illumination angle received by the photovoltaic cell at present;

Specifically, the illuminance intensity received by the current photovoltaic cell can be obtained by using an illuminance sensor or an illuminance meter, the ambient temperature in which the photovoltaic cell is positioned is measured by using a temperature sensor or a thermometer, and the angle of illumination is measured by using an inclination angle sensor or an inclination meter. The sensor can be arranged on the photovoltaic cell panel or at the surrounding position, and the current illumination angle is obtained by detecting the angle of light. In addition to the provision of the sensor, a display screen may be provided in connection with the sensor. The illumination intensity sensor obtains the data of the current illumination intensity, the ambient temperature and the illumination angle through the sunlight irradiation degree, and the illumination intensity, the ambient temperature and the illumination angle in the current external environment are displayed on the display screen in real time according to the data transmitted by the illumination intensity sensor.

Step S202, determining the current working state of the photovoltaic cell at least according to the value of the current illumination data, wherein the current working state at least comprises that the photovoltaic cell needs to be cleaned, the photovoltaic cell does not need to be cleaned, the photovoltaic cell needs to be adjusted and the photovoltaic cell does not need to be adjusted;

In particular, photovoltaic cells require cleaning in cases where, for example: dust, dirt, bird droppings and other impurities can be accumulated on the surface of the photovoltaic cell which is not cleaned for a long time, so that the power generation efficiency of the photovoltaic cell is affected; in the sand weather, flying sand can cover the surface of the photovoltaic cell, influence the transmission and reflection of illumination, and reduce the power generation efficiency; or after rainy and snowy weather, water stains or snow possibly remain on the surface of the photovoltaic cell to influence the transmission and reflection of illumination, and the photovoltaic cell needs to be cleaned to restore the normal power generation efficiency. The photovoltaic cell needs to be tuned, for example, in the following cases: the installation angle of the photovoltaic cell panel needs to be adjusted according to seasons and geographic positions so as to capture solar energy to the greatest extent; if the surface of the photovoltaic cell panel is affected by dust, dirt or snow, cleaning and maintenance are required to maintain the illumination efficiency; when the photovoltaic cell panel is in fault or damage, the photovoltaic cell panel needs to be overhauled and maintained so as to ensure normal operation; when the output power of the photovoltaic cell panel is not in line with the expectation, the photovoltaic cell panel needs to be adjusted and optimized to improve the energy utilization rate.

Step S203, when the current working state of the photovoltaic cell is that the photovoltaic cell needs to be adjusted, adjusting the photovoltaic cell to improve the photoelectric conversion efficiency of the photovoltaic cell;

Specifically, the photoelectric conversion efficiency of the photovoltaic cell can be improved to a certain extent by adjusting the unfolding area of the photovoltaic cell, adjusting the illumination angle of the photovoltaic cell, adjusting the temperature of the photovoltaic cell, adjusting the angle between the photovoltaic cell and the ground plane and the like.

Step S204, under the condition that the current working state of the photovoltaic cell is that the photovoltaic cell needs cleaning, the photovoltaic cell is processed to improve the photoelectric conversion efficiency of the photovoltaic cell.

In particular, cleaning materials can be used to wipe the photovoltaic cell surface to remove dust and dirt. If the surface has more tough dirt, the surface can be cleaned with a mild detergent or light brine and then thoroughly rinsed with clear water. The use of a cleaning agent containing alcohol, ammonia or a frosting component is avoided so as not to damage the surface of the photovoltaic cell.

Through the embodiment, first, current illumination data of a photovoltaic cell is obtained, wherein the illumination data at least comprises illumination intensity received by the current photovoltaic cell, environment temperature of the current photovoltaic cell and illumination angle received by the current photovoltaic cell; determining the current working state of the photovoltaic cell at least according to the value of the current illumination data; under the condition that the current working state of the photovoltaic cell is that the photovoltaic cell needs to be adjusted, the photovoltaic cell is adjusted to improve the photoelectric conversion efficiency of the photovoltaic cell; and under the condition that the current working state of the photovoltaic cell is that the photovoltaic cell needs to be cleaned, the photovoltaic cell is treated to improve the photoelectric conversion efficiency of the photovoltaic cell. According to the method, the working state of the photovoltaic cell panel is determined according to illumination data such as the current illumination intensity, the current ambient temperature and the current illumination angle of the photovoltaic cell, wherein the working state can determine whether the photoelectric conversion efficiency of the photovoltaic cell panel meets the requirement, and corresponding measures are timely taken to improve the photoelectric conversion efficiency of the photovoltaic cell panel and maximize the utilization of photovoltaic power generation resources under the conditions that the photovoltaic cell panel needs to be cleaned and the photovoltaic cell panel needs to be adjusted. The problem of the photovoltaic cell among the prior art photoelectric conversion efficiency is not ideal is solved.

In a specific implementation process, under the condition that the current illumination data is the illumination intensity received by the current photovoltaic cell, the step S202 may be implemented by: step S2021, determining whether the illumination intensity is less than a light intensity threshold, and determining that the current working state of the photovoltaic cell is that the photovoltaic cell needs to be adjusted when the illumination intensity is less than the light intensity threshold; step S2022, determining that the current operating state of the photovoltaic cell is that the photovoltaic cell does not need to be adjusted when the illumination intensity is equal to or greater than the light intensity threshold. The method can further determine whether the photovoltaic cell needs to be adjusted according to the illumination intensity and the light intensity threshold.

Specifically, in practical application, the higher the illumination intensity is, the higher the power generation efficiency of the photovoltaic cell panel is, because the higher the illumination intensity is, the larger the energy of photons is, so that more electrons can be excited to jump from the semiconductor material, and more current is generated. When the illumination intensity is insufficient, the power generation efficiency of the photovoltaic cell panel is reduced, and even the power generation is stopped. This is mainly because the photovoltaic panel cannot absorb enough photon energy to excite electron transitions when the illumination intensity is insufficient. In addition, the change of illumination intensity can also influence the output voltage and current of the photovoltaic cell panel. The higher the illumination intensity, the higher the output voltage and current; the smaller the illumination intensity, the smaller the output voltage and current.

In order to further accurately determine whether the photovoltaic cell needs to be adjusted, in the case that the current illumination data is the illumination intensity received by the photovoltaic cell, the step S202 of the present application may further be implemented by: step S2023, obtaining the current power generation amount of the photovoltaic cell, and calculating the current photoelectric conversion efficiency of the photovoltaic cell according to the power generation amount and the illumination intensity, where the photoelectric conversion efficiency is the ratio of the light energy absorbed by the current photovoltaic cell under the condition of the illumination intensity to the power generation amount; step S2024, determining whether the photoelectric conversion efficiency is less than an efficiency threshold, and determining that the current operating state of the photovoltaic cell is that the photovoltaic cell needs to be adjusted if the photoelectric conversion efficiency is less than the efficiency threshold; in step S2025, when the photoelectric conversion efficiency is equal to or greater than the efficiency threshold, it is determined that the current operating state of the photovoltaic cell is that the photovoltaic cell does not need to be adjusted.

Specifically, whether the photovoltaic cell needs to be adjusted is determined directly according to the illumination intensity and the light intensity threshold, the current photoelectric conversion efficiency of the photovoltaic cell can be calculated according to the generated energy and the illumination intensity, and whether the photovoltaic cell needs to be adjusted is determined according to the photoelectric conversion efficiency. The photoelectric conversion efficiency can be calculated according to the following formula: photoelectric conversion efficiency= (power generation amount/(illumination intensity x surface area of photovoltaic cell)) ×100%.

In the case where the current illumination data is the illumination intensity received by the photovoltaic cell, the step S202 may be implemented in other manners, for example: step S2026, determining a light intensity change rate according to the light intensity, where the light intensity change rate is a change rate of the current light intensity of the photovoltaic cell in a predetermined period of time; step S2027, determining whether the light intensity change rate is greater than a rate threshold, and determining that the current operating state of the photovoltaic cell is that the photovoltaic cell needs cleaning when the light intensity change rate is greater than the rate threshold; in step S2028, when the rate of change of the light intensity is equal to or less than the rate threshold, it is determined that the current operating state of the photovoltaic cell is that the photovoltaic cell does not need to be cleaned. The method can further determine whether the photovoltaic cell needs cleaning according to the light intensity change rate.

Specifically, in practical application, if the illumination intensity of the photovoltaic cell is obviously changed within a predetermined period of time, the effect of the photoelectric conversion efficiency of the photovoltaic cell panel is indicated, and cleaning is required.

In some embodiments, in the case where the current illumination data is the current ambient temperature of the photovoltaic cell, the step S202 may be implemented specifically by: step S2029 of determining whether the ambient temperature is equal to or higher than a first temperature threshold and lower than a second temperature threshold, and determining that the current operating state of the photovoltaic cell is that the photovoltaic cell does not need to be adjusted when the ambient temperature is equal to or higher than the first temperature threshold and lower than the second temperature threshold, wherein the first temperature threshold is lower than the second temperature threshold; step S20210, determining that the current operating state of the photovoltaic cell is that the photovoltaic cell needs to be adjusted if the ambient temperature is less than the first temperature threshold or greater than the second temperature threshold. The method may further determine whether the photovoltaic cell needs to be adjusted based on the ambient temperature and the temperature threshold.

In particular, the efficiency of the photovoltaic panel decreases with increasing temperature, since high temperatures increase the recombination rate of electron-hole pairs inside the photovoltaic panel, thus reducing the output power of the panel. In addition, the output voltage of the photovoltaic cell panel is affected by the change of the ambient temperature, and at high temperature, the internal resistance of the photovoltaic cell panel is reduced, so that the output voltage is reduced. Too high a temperature can also accelerate the aging process of the photovoltaic panel, reducing its service life.

In the case where the current illumination data is the angle of illumination received by the photovoltaic cell, the step S202 may be implemented specifically by: step S20211, determining whether the angle of the light is greater than or equal to an angle threshold, and determining that the current operating state of the photovoltaic cell is that the photovoltaic cell needs to be adjusted when the angle of the light is greater than or equal to the angle threshold; step S20212, determining that the current operating state of the photovoltaic cell is that the photovoltaic cell does not need to be adjusted if the angle of the illumination is less than the angle threshold. The method can further determine whether the photovoltaic cell needs to be adjusted according to the illumination angle and the angle threshold.

Specifically, the illumination angle directly influences the efficiency of receiving light energy of the photovoltaic cell panel, the generated power and the temperature of the photovoltaic cell panel. When the illumination angle is larger, the light rays are reflected or transmitted more, so that the capturing efficiency of the light energy is reduced; when the illumination angle is smaller, light rays are easier to vertically irradiate on the photovoltaic cell panel, and the capturing efficiency of light energy is improved. In the case of vertical illumination, the power generated by the photovoltaic panel is maximum, and in the case of oblique illumination of light, the power generated is reduced. When the illumination angle is larger, the photovoltaic cell panel is more easily subjected to direct sunlight, so that the temperature is increased, and the working state and the power generation efficiency of the photovoltaic cell panel are affected.

The step S203 may be specifically implemented by one of the following steps: step S2031, increasing an expansion area of the photovoltaic cell, where the expansion area is an area of the photovoltaic cell for receiving solar energy; step S2032, adjusting the bracket angle of the photovoltaic cell, wherein the bracket angle is the angle between the photovoltaic cell and the ground; and step S2033, adjusting the orientation of the photovoltaic cell, where the orientation is the direction in which the photovoltaic cell faces the sun. The method can further and rapidly adjust the photovoltaic cell to improve the photoelectric conversion efficiency of the photovoltaic cell.

Specifically, the more compact layout mode is adopted, so that the unfolding area of the photovoltaic cell panel is larger, and the unfolding area of the photovoltaic cell panel can be enlarged by adding the supporting structure. The angle of the support of the photovoltaic cell can be adjusted according to the latitude and the season of the area, so that the photovoltaic cell can absorb sunlight to the greatest extent. Generally, the bracket angle should be equal to the latitude of the area where the bracket is located, while being finely adjusted according to the solar altitude in summer and winter. Further, a solar tracking system may also be used. The system can automatically adjust the angle of the bracket according to the position of the sun so as to ensure that the photovoltaic cell always faces the sun ray.

The step S204 may be specifically implemented by one of the following steps: step S2041, replacing the photovoltaic cell by a preset photovoltaic cell, wherein the photoelectric conversion efficiency of the preset photovoltaic cell is larger than that of the photovoltaic cell; and step S2042, cleaning the photovoltaic cell to remove surface pollution of the photovoltaic cell. The method can further clean the photovoltaic cells rapidly.

In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the control method of the photovoltaic cell of the present application will be described in detail below with reference to specific embodiments.

The embodiment relates to a specific control method of a photovoltaic cell, as shown in fig. 3, including the following steps:

Step S2: connecting the illumination intensity sensor with a control display panel, and displaying data transmitted by the illumination intensity sensor on the display panel in real time by the illumination intensity system;

Step S3: the illumination intensity system compares the data returned by the illumination intensity sensor, and when the illumination intensity is lower than a certain intensity value, the photovoltaic cell panel is controlled to expand more area to absorb more light energy;

Step S4: the angle and the orientation of the photovoltaic cell panel are adjusted in real time according to the data of the power generation rate of the photovoltaic cell panel, and the solar energy is absorbed maximally;
