对γ射线辐照时间对SnO2/n-Si异质结器件的影响进行了实验和理论分析。在室温下，伽马射线暴露时间分别为（t= 0、50、100和150 min）。光照功率强度为9.5 mw/cm。随着辐照时间的增加，光电流增大。我们估计了这种效应的理论模型，以获得任何辐照时间的（J -V）曲线，我们没有进行实验。采用“Table curve 2D, version 5.01”程序对所有实验数据进行拟合曲线。得到的最佳理论方程为：Y= a + b x +c e。得到了试验辐照时间（t= 75和125 min）的理论曲线，并与实验数据进行了拟合，两者具有较好的相似性。在这项工作中，我们展示了一项实验研究和理论分析，即照明功率强度对Cs 137照射150分钟的SnO2/n-Si异质结器件的影响。伽马射线。（J-V）特性绘制为照明功率强度（1.95、2.88、3.78、5.9和9.5）mw/cm的函数。该装置的效率不断提高，直到最高效率达到9.5 mw/cm，这是最佳情况。通过使用“Table Curve 2D version 5.01”程序对该过程进行理论分析，从而估计出理论建模方程：Y= a + b x +c e。我们计算了这些参数（a， b和c）作为功率强度的函数，并测试了功率强度（4和8 mw/cm）的方程。用实验数据绘制了理论（JV）曲线。它们之间有很好的一致性，两条曲线的行为包含线性项和指数项。
An experimental and theoretical analysis of the effect of irradiation time to Gamma ray on the SnO2/n-Si hetero-junction devices have been carried out. The time of exposure to Gamma ray was taken as (t= 0, 50, 100, and 150 min.) at room temperature. The power intensity of illumination was 9.5 mw/cm. Increasing irradiation time led to increase in photo current. We estimate theoretical model for this effect to obtain (J –V) curve for any irradiation time that we do not take experimentally. “Table curve 2D, version 5.01” program was used to make the fitting curve for all experimental data. The best estimated theoretical equation was :Y= a + b x +c e. Theoretical (JV) curve has been achieved for test irradiation time (t= 75 and 125 min.) and plotted with experimental data, there is a good similarity between them. In this work we have demonstrated an experimental study and theoretical analysis of the effect of power intensity of illumination on the SnO2/n-Si Heterojunction devices that have been irradiated with Cs 137 for 150 min. Gamma ray. The (J-V) characteristic was plotted as function of power intensity of illumination (1.95, 2.88, 3.78, 5.9, and 9.5) mw/cm. There was an increase in efficiency of this device until maximum efficiency reached at 9.5 mw/cm represents optimal case. Theoretical analysis of this process was achieved by using “Table Curve 2D version 5.01” program leading to estimate theoretical modeling equation : Y= a + b x +c e. We have calculated these parameters (a, b, and c) as function of power intensity and tested the equation for power intensity (4 and 8 mw/cm). Theoretical (JV) curves have been plotted with experimental data. There is a good agreement between them and the behavior of these two curves contains linear term and exponential term.
