Since solar cell output voltage and current both depend on temperature, the actual output power will vary with changes in ambient temperature. As discussed earlier, semiconductor solar cells fundamentally consist of a p-n diode (as shown in Fig. 48.1a,b). Photocurrent is generated under light illumination on the p-n diode.
