Performance analysis of a multi-surface compound solar photovoltaic cell

提出一种新型多曲面槽式太阳聚光器,用于太阳能聚光光伏发电应用,其结构主要由多块铝板拼接成多个曲面并固定在型材上。聚光接受体为太阳电池。对平板多晶硅太阳电池和槽式聚光多晶硅太阳电池的发电性能进行实验比较,结果表明,无论在晴天或多云天气,槽式聚光太阳电池发电系统均能提高输出电功率,最大输出电功率是其不聚光时的4.4倍。在测试时间,内聚光光伏发电系统总输出电功率最大值是其不聚光时的4.30倍。

A new type multi-surface compound solar through concentrator for solar concentrator photovoltaic utility was presented in this paper.The concentrator was composed of multi-inlaid aluminum sheets fixed in a flat frame,and the concentrator receiver was solar cell panel.The comparative experiments of solar cell module of polycrystalline silicon cell and through concentrating polycrystalline silicon cell were made.The results indicate that,no matter in the sunny and cloudy day,the maximum output electric power of through concentrating PV system is higher than that of flat-plate PV system.The maximum output electric power of through concentrating PV system is 4.4 times of flat-plate PV system.During experiments period,the maximum total output electric power of though concentrating PV system is 4.30 times of flat-plate PV system.
