Abstract

The effect of ionizing radiations (Alpha, Beta, Gamma) in CdS/p-Si heterojunction solar cells are discussed in this paper. The short-circuit current density parameters before Gamma irradiation conditions have been improved up to 35 mA/cm2 and after Gamma irradiation was 30 mA/cm2. The open circuit voltage before Gamma irradiation was 0.59 and 0.565 V after Gamma irradiation. The limitations of these devices were discussed by investigating the dependence of electrical and efficiency parameters in function of radiation time. The efficiency of the cell before radiation was equal to (11.2%) whenever, after the impact of both Alpha, Beta, and Gamma was follows, 4.7, 4.9, and 5.1% respectively. The fill factor before and after Gamma irradiation was 54.5 and 53 %. Studying and analyzing the cells using the I-V, with the change of time rate of Gamma radiation played a critical role in reducing the efficiency of solar cells. The campaign was carried out with different doses of a series of solar cells by exposing them to different time. The deterioration parameters of CdS/p-Si solar cells by Gamma radiation led to strongly supports the results of minority carrier lifetime, which clearly showed diminishing minority carrier lifetime with increasing radiation dose.
电离辐射(α, β, γ)对CdS / P-Si异质结太阳能电池电学和光学性能的影响
本文讨论了电离辐射(α, β, γ)对CdS/p-Si异质结太阳能电池的影响。辐照前短路电流密度参数提高到35 mA/cm2,辐照后短路电流密度参数提高到30 mA/cm2。辐照前开路电压为0.59 V,辐照后开路电压为0.565 V。通过研究电学参数和效率参数与辐射时间的关系,讨论了这些器件的局限性。在Alpha, Beta和Gamma的影响之后,细胞在辐射前的效率等于(11.2%),分别为4.7,4.9和5.1%。辐照前后的填充因子分别为54.5%和53%。利用I-V随时间速率的变化对太阳能电池进行研究和分析,对降低太阳能电池效率起着至关重要的作用。研究人员将一系列不同剂量的太阳能电池暴露在不同的时间。伽马辐射对CdS/p-Si太阳电池的劣化参数有力地支持了少数载流子寿命的结果,即随着辐射剂量的增加,少数载流子寿命明显减小。
