We define the recombination time of excess electrons in p field as the minority carrier lifetime . in theory, we developed the equation between excess minority carriers lifetime and the open-circuit voltage decay; moreover, the effect of capacitance to general open-circuit voltage is also investigated . both different efficiency solar cells are measured by the method and showed the relations between the minority carrier lifetime and the performance of solar cells, which provides great useful guidelines for fabricating high-efficiency silicon solar cell in industry 根據(jù)太陽電池的工作原理,詳細地論述了用脈沖光源照射n/p結太陽電池時光電壓的產(chǎn)生,理論上給出了注入p區(qū)的電子復合帶來的開路電壓與少子壽命的關系,也研究了n/p結勢壘電容放電對開路電壓衰減的影響關系,推導了利用開路電壓隨時間衰減的關系來測量少數(shù)載流子壽命的理論公式。
