The effect of temperature on the performance parameters [short-circuit current density (J_SC), open-circuit voltage (V_OC), fill factor (FF), and conversion efficiency (η)] of stand-alone germanium (Ge) solar cells has been theoretically investigated. Although J_SC increased with increasing temperature, η decreased due to a decrease in V_OC and the associated decrease in the FF. The performance parameters J_SC, V_OC, FF, and η of a fabricated stand-alone Ge solar cell were determined from current–voltage (I–V) measurements. The significant differences between the obtained theoretical and experimental data may be related to both the use of idealized cases in the theoretical studies and the loss mechanisms considered to adversely affect the performance of the fabricated stand-alone Ge solar cell.

独立锗（Ge）太阳能电池的综合研究

温度对性能参数[短路电流密度（效果Ĵ _SC），开路电压（V _OC），填充因子（FF）和转换效率（η）]单机锗（Ge）的太阳能对细胞进行了理论研究。尽管J _SC随着温度的升高而增加，但由于V _OC的降低以及FF的降低，η降低。制备的独立式Ge太阳能电池的性能参数J _SC，V _OC，FF和η由电流-电压确定（I –V）测量。获得的理论和实验数据之间的显着差异可能与理论研究中理想情况的使用以及被认为对制造的独立式Ge太阳能电池的性能产生不利影响的损失机制有关。
