【摘要】 为了分析太阳电池特性参数对转换效率的影响,将遗传算法引入到太阳电池的I-V曲线的拟合。针对太阳电池数学模型的特点,在编码方式与交叉算子等方面对遗传算法进行改进,利用MATLAB工具进行计算,较准确地获取太阳电池特性参数。并对太阳电池特性参数对太阳电池转换效率的影响进行分析。结果表明:改进后的遗传算法较精确地获取了太阳电池的5个特性参数,在串联电阻Rs小,暗电流小的情况下,可增加并联电阻Rsh与光照面积,可提高转换效率。更多还原

【Abstract】 In order to analyze the characteristics parameters of solar cell’s influence to the transform efficiency,the GA algorithm has been used to fitting I-V curve.According to the characteristic of solar cell’s mathematical model equation,the coding way and cross probability have been improved and the Matlab has been used to calculate.The computer simulation has been done.The result show that the improved GA can obtain five craftwork parameters of solar cell precisely,and can enhance the transform efficiency by increasing the R_sh and lighting area when the value of R_s and dark electric current is small更多还原
