研究目的
Investigating the effect of Co-60 Gamma irradiation on the electrical characteristics of CdTe/CdS solar cells.
研究成果
The study concluded that Co-60 Gamma irradiation significantly affects the electrical properties of CdTe/CdS solar cells, with increases in ideality factor and reverse leakage current, and a decrease in series resistance. The solar cells showed good stability against gamma irradiation, with potential for damage mitigation through low temperature annealing.
研究不足
The study is limited to the effects of Co-60 Gamma irradiation on CdTe/CdS solar cells under dark conditions. The potential for low temperature annealing to mitigate radiation damage was mentioned but not explored in depth.
1：Experimental Design and Method Selection:
The study involved in-situ current-voltage characterization (I-V) in dark conditions to analyze the effect of Co-60 Gamma irradiation on CdTe/CdS solar cells. The irradiation doses ranged from 1kGy to 100 kGy.
2：Sample Selection and Data Sources:
CdTe/CdS solar cells were used as samples. The electrical parameters such as ideality factor (n), series resistance (RS), and reverse bias leakage current (IR) were calculated from the I-V characteristics.
3：List of Experimental Equipment and Materials:
Co-60 Gamma irradiation source, CdTe/CdS solar cells, and equipment for I-V characterization.
4：Experimental Procedures and Operational Workflow:
The solar cells were irradiated with Co-60 Gamma rays at various doses, and their I-V characteristics were measured in dark conditions.
5：Data Analysis Methods:
The data was analyzed using thermionic emission theory to calculate the ideality factor, series resistance, and reverse leakage current.
