detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention. As shown in FIG. 1 , it is a structural diagram of a mobile phone with solar cell thin film function according to the present invention. The structure diagram is illustrated by taking a mobile phone as an example. The structure 100 includes: a terminal touch panel TP10 with a solar cell film function, a charging control circuit 20, a battery 30, a PMIC circuit 40, an infrared reflection control circuit 50, and a charging efficiency display circuit. 60.

The PMIC circuit 40 is a power management chip (PowerManagementIC), and the battery 30 provides the Vbattery main power supply for the PMIC circuit 40. The PMIC circuit 40 is mainly used to pass through an internally integrated LDO (LowDropOutregulator, low dropout linear regulator), DC-DC converter, etc. , to power the radio frequency and baseband modules of mobile phones.

In the present invention, a layer of transparent solar cell film is added under the common mobile phone touch panel TP10 to receive light irradiation to realize solar charging. The transparent solar cell film has high transparency and simultaneously has the function of a solar cell. In a preferred embodiment, the thickness of the transparent solar cell film is less than 0.1 mm. Because the thickness of the transparent solar cell film is relatively small, and the organic polymer thin layer is used as the substrate, the transparent electrode is used, and the transparency is high, so the use of the touch panel TP10 and the display of the LCD liquid crystal screen will not be affected. The transparent solar cell film can be a polysilicon solar cell film.

The transparent solar cell film arranged under the touch panel TP10 generates photovoltaic action under light irradiation, performs photoelectric conversion, and charges the battery 30 through the charging control circuit 20 built in the mobile phone.

The charging control circuit 20 built in the mobile phone controls whether to charge the battery 30 by comparing the battery power with the set value:

When the battery power Vbat is lower than a set value Va, the charging control circuit 20 charges the battery 30, and when the battery power Vbat is higher than a set value Vb, the charging control circuit 20 stops charging the battery 30 to protect the battery. 30. The battery 30 may be a lithium ion battery.

Further, the set value Va and the set value Vb can be set according to actual needs.

Since the infrared rays in the external light will cause the touch panel TP10 to generate heat, a special infrared reflection control circuit (IrReflectionControl Circuit) 50 needs to be provided to reflect the external infrared rays.

Furthermore, since the light intensity of each environment is different, or the angle of illumination on the touch panel TP10 is different, the photoelectric conversion efficiency will be different. Therefore, the display of the real-time charging efficiency of the terminal (ChargingEfficiencyDisplay, x%) is introduced, and the The charging efficiency display circuit 60 is implemented, and the charging efficiency display circuit 60 displays the real-time charging efficiency on the touch panel TP10.

When the real-time charging efficiency of the terminal is higher than x%, the charging control circuit 20 directly charges the battery 30 .

When the real-time charging efficiency of the terminal is lower than x%, the charging efficiency display circuit 60 prompts the terminal user to adjust the position and angle at any time to improve the charging efficiency.

As shown in FIG. 2 , it is a structure diagram of a mobile phone touch panel with solar cell thin film function according to the present invention. The mobile phone touch panel TP10 includes six layers in structure, which are: first polyester plastic layer 21, ITO conductive layer 22, second polyester plastic layer 23, plexiglass base layer 24, transparent solar cell film layer 25, transparent The solar cell thin film layer 25 is arranged on the LCD 26 of the mobile phone, and these six layers are arranged from top to bottom by means of addition. The first polyester plastic layer 21 , the ITO conductive layer 22 , the second polyester plastic layer 23 , the plexiglass base layer 24 , and the transparent solar cell film layer 25 jointly constitute a new mobile phone touch panel TP10 .

In order to deal with the problem of heat generated by the solar cell film working for a long time, through holes 211 are opened on the surface of the first polyester plastic layer 21 to dissipate heat. The through hole 211 has a diameter of 0.1-0.2 mm and is located on the edge of the touch panel TP10 so as not to affect the appearance and function of the touch panel TP10 .

The solar photoelectric conversion function of the transparent solar cell film layer 25 in the touch panel TP10 is always on.

When there is no external light, the solar photoelectric conversion of the transparent solar cell film layer 25 cannot work;

When the lithium-ion battery 30 is fully charged, the charging control circuit 20 stops charging the lithium-ion battery 30;

When the electric quantity of the lithium ion battery 30 is zero, the solar photoelectric conversion of the transparent solar cell film layer 25 automatically charges the lithium ion battery 30 .

Fig. 3 is a working flow chart of the mobile phone touch panel with solar cell thin film function according to the present invention. Combined with Figures 1 and 2, the workflow includes the following steps:

Step 300, external light irradiates the touch panel TP10 with a solar cell film, and the external light includes visible light, infrared light, and ultraviolet light;

In this step, in order to prevent the touch panel TP10 from overheating after the infrared rays in the external light are transmitted, the infrared rays are reflected by the infrared reflection control circuit 50 .

Step 301, the touch panel TP10 with solar cell film works;

Step 302, performing photoelectric conversion on the light energy generated by the transparent solar cell film 25;

Step 303, the charging efficiency display circuit 60 displays the real-time charging efficiency on the touch panel TP10, and when the real-time charging efficiency is greater than x%, the charging control circuit 20 directly charges the battery 30, otherwise prompts the end user to adjust the position and angle at any time;

Step 304, when the charging control circuit 20 judges that the power Vbat of the battery 30 is lower than the set value Va, it charges the battery 30 of the mobile phone, and when the power Vbat of the battery 30 is higher than the set value Vb, stops charging the battery 30 of the mobile phone ;

Step 305, end.

The above embodiments describe the technical solution of the present invention by taking the mobile phone as an example, but the present invention is not limited to the mobile phone, and may also be other terminals, such as PDA.

In the present invention, by adding a layer of transparent solar cell film on the touch panel TP of the mobile phone, it can provide solar charging in real time under the environment of light irradiation.

In addition, solar thin film materials are durable, lightweight, efficient, and flexible, and are suitable for mass production and application. The invention realizes the long-time battery life of the mobile phone, and facilitates users to use the mobile phone anytime and anywhere more conveniently and for a longer period of time.

The invention realizes the emergency endurance of the mobile phone battery in an emergency situation, and facilitates users to use the mobile phone more conveniently anytime and anywhere.

The touch panel T/P with the solar cell thin film of the present invention can generate electricity in an environment with visible light, but in cloudy days, dark places, and under fluorescent lamps, the electricity conversion efficiency will be reduced. Operates best in full sun in direct sunlight.
