Description

Photovoltaic and photothermal integrated assembly

Technical Field

The utility model belongs to the solar energy field, concretely relates to photovoltaic light and heat integration subassembly.

Background

Photovoltaic modules in the current market are photoelectric conversion equipment with single performance, and after a photovoltaic power generation system is laid, the system only has a single power generation function and can only provide single electric energy for users; and in fact the user requires heat energy, such as hot water, at the same time as the electrical energy.

When the photovoltaic module realizes photoelectric conversion, partial light radiation is absorbed to generate a photovoltaic effect and generate current, and simultaneously heat generated by illumination is also absorbed, so that the working temperature of the photovoltaic module is increased, and the internal resistance of the module is increased along with the increase of the working temperature of the module, thereby influencing the generating efficiency of the module. The open-circuit voltage of the single solar cell is reduced along with the rise of the temperature, the voltage temperature coefficient is- (210-212) mV/DEG C, namely, the open-circuit voltage of the single solar cell is reduced by 210-212 mV when the temperature rises by 1 ℃ every time; the solar cell short-circuit current increases with the increase of temperature; the peak power of a solar cell decreases with increasing temperature, so that the increasing temperature directly affects the power generation efficiency, for example, a silicon solar cell operating at 20 ℃ has an output power 20% higher than that of a silicon solar cell operating at 70 ℃. A monolithic solar cell module typically consists of 36 individual solar cells connected in series. According to the results of field measurement in the Xining area, the back surface temperature of the solar cell module can reach 70 ℃ in summer, the working junction temperature of the solar cell can reach 100 ℃ (the rated parameters are calibrated under the condition of 25 ℃), the open circuit voltage of the module is reduced by about 213 x (100-25) 36-6210 mV compared with the rated value, and the peak power loss rate is about 14% x (100-25) 30%. Therefore, when the silicon solar cell works at a higher temperature, the open-circuit voltage is greatly reduced along with the rise of the temperature, and meanwhile, the serious deviation of a charging working point is caused, so that the system is easy to damage due to insufficient charging; the output power of the silicon solar cell also drops greatly with the rise of the temperature, so that the solar cell module can not fully exert the maximum performance. Therefore, heat generated during solar photovoltaic power generation is detrimental to the power generation system.
