Solar Energy
The best solar cell with a high E ff (22.67%), high V oc (699 mV), and low reverse-biased junction leakage current (I Rev) of 0.15 A at −14.5 V was obtained using the cleaning method (process III) involving HF/HNO 3 and polish solution.
Effect of Temperature
The above equation shows that the temperature sensitivity of a solar cell depends on the open-circuit voltage of the solar cell, with higher voltage solar cells being less affected by temperature. For silicon, E G0 is 1.2, and using γ as 3 gives a reduction in the open-circuit voltage of about 2.2 mV/°C;
