【摘要】 以某CTJ 10 mm×10 mm聚光三结太阳电池接收器为研究对象,建立了太阳电池的热学及电学模型,改进了太阳电池的效率表达式。利用MATLAB编程对无散热条件下的太阳电池温度进行了分析计算,得出了在不同环境温度和对流换热系数条件下的太阳电池温度随聚光比变化的规律。计算结果显示:在环境温度为25℃、对流换热系数为5 W/(m2.K)的条件下,500倍聚光对应的太阳电池温度高达492.6℃。更多还原

【Abstract】 The temperature analysis based on a CTJ 10 mm×10 mm concentrator solar cell was made.The thermal and electrical model of solar cell was established,and the expression of solar cell’s efficiency was retrofitted.The cell’s temperature under different concentration ratios was obtained by solving the coupled equations of electrical and thermal model using MATLAB program.According to the results,the cell’s temperature reaches about 492.6 ℃ under 500 C concentrations with the ambient temperature of 25 ℃ and the convection heat transfer coefficient of 5 W /(m2·K).更多还原
