Somewhat less obvious is the fact that photodiode leakage and photovoltaic cell internal losses are also functions of terminal voltage. 此外，光电二极管的漏电流和光电池的内部损耗也是其端电压的函数。
The problems of the classic equivalent circuit of a photoelectric cell based on photovoltaic effect are analyzed, and a modified equivalent circuit is presented. 本文指出按经典光伏理论给出的光电池等效电路存在的问题，给出改进的光电池的等效电路。
