Abstract

The results of the studies of changes in the electro-physical parameters (V_oc, open circuit voltage; I_sc, short-circuit current density; τ, lifetime of nonequilibrium charge carriers) of photocells made on plates of monocrystalline silicon of the p-type conductivity with the specific resistance ρ 0.5 Ohm cm, doped with nickel, under irradiation with γ-quanta from ⁶⁰Co source are presented. It is shown that the efficiency of the solar energy conversion in nickel-doped photovoltaic cells remains higher than in standard cells up to irradiation doses of 10⁸ rad. It was established that radiation stability of electrophysical parameters of photovoltaic cells also increases with increasing diffusion temperature of nickel atoms. A decrease in the concentration of recombination-active radiation defects is due to the gettering by nickel atoms of technological (background) impurities and the action of nickel clusters as effluents for radiation-induced vacancies.

本文介绍了在掺镍的 p 型导电单晶硅板（比电阻 ρ 0.5 欧姆厘米）上制造的光电池在 60Co 源的γ 量子辐照下的电物理参数（Voc，开路电压；Isc，短路电流密度；τ，非平衡电荷载流子寿命）变化的研究结果。结果表明，掺镍光伏电池的太阳能转换效率在 108 拉德的辐照剂量下仍高于标准电池。研究还证实，随着镍原子扩散温度的升高，光伏电池电物理参数的辐射稳定性也会提高。重组活性辐射缺陷浓度的降低是由于镍原子对技术（背景）杂质的脱落以及镍簇作为辐射诱导空位的排出物的作用。
