Customer ServiceThis study conducts a simulation of the performance of a solar cell on PC1D software at three different temperatures within a controlled environment. The parameters were modeled on a 200 cm 2 silicon solar cell. The rise of 5 °C decreases the power output by 2% while the increase of 20°C decreased the power output by 10.4%.
Customer ServiceThe objective of this research is to identify the temperature effect on the solar photovoltaic (PV) power generation and explore the ways to minimize the temperature effect. The photovoltaic (PV) cells suffer efficiency drop as their operating temperature increases especially under high insolation levels and cooling is beneficial.
After observing the above system it has been identified that, when the PV modules temperature decreases the overall efficiency of the PV panel output power increases. From the gathered data, a suitable photovoltaic thermal system (automated active cooling) is designed with Arduino UNO board for solar panels.
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.
Illustrated in Fig. 4 is the correlation between solar cell efficiency and temperature. As temperature rises, efficiency experiences a decline attributed to heightened electron–hole recombination rates and alterations in the bandgap properties of materials.
The temperature effect of SCs will affect the intrinsic properties of SC materials and the parameters that characterize SC performance. This will ultimately affect its power generation efficiency. This work reviews previous studies on temperature effects in SCs.
