The absolute temperature coefficient of the photovoltaic cell efficiency can be determined by linear fitting of the efficiency dependence on the temperature. The efficiency is calculated as follows: where A represents the area of the photovoltaic cell and It is the irradiance.
The actual value of the temperature coefficient, in particular, depends not only on the PV material but on T ref , as well. It is given by the ratio 1 ref oref TT (4) in which T o is the (high) temperature at , Garg and Agarwal . For crystalline silicon solar cells this temperature is 270 o C, Evans and Florschuetz .
The absolute and normalized temperature coefficients are determined and compared with their values from the related literature. The variation of the absolute temperature coefficient function of the irradiance and its significance to accurately determine the important parameters of the photovoltaic cells are also presented.
Considering from the perspective of light, the increase in temperature is beneficial to PV power generation, because it will increase the free electron–hole pairs (i.e., carriers) generated by the PV effect in the cell to a certain extent . However, excessively high temperature cannot increase the final output of the SC.
The temperature effect of PV cells is related to their power generation efficiency, which is an important factor that needs to be considered in the development of PV cells.

By analyzing the FF dependency function of the temperature, it is observed that the FF temperature coefficient of the amorphous photovoltaic cell is the smallest and the FF temperature coefficient of the monocrystalline photovoltaic cell is the highest. This situation is the same for all illumination levels taken into consideration.
