Enhanced power conversion performance of multi-crystalline silicon photovoltaic modules with half-cell electronic structure and optical gain structure

摘要: 在工业产线上制备了多晶硅光伏组件,并研究了半片电学结构与光学增益结构对其光电转换性能的影响。结果表明:半片电学结构提升了多晶硅光伏组件的填充因子,光学增益结构提升了多晶硅光伏组件的短路电流。二者叠加使多晶硅光伏组件的光电转换效率提升到了19.26%,最大发电功率超过313 W。集成的光电结构提升多晶硅光伏组件性能的物理原因可归结为半片电学结构降低了组件的串联电阻及光学增益结构提升了组件中的光利用。

Abstract: Multi-crystalline silicon（mc-Si） photovoltaic modules with a half-cell electronic structure and an optical gain structure are successfully fabricated on an industrial scale. The mc-Si photovoltaic modules exhibit enhanced fill factor and short-circuit current, resulting in high power conversion efficiency of up to 19.26%. The enhanced optoelectronic conversion is attributed to reduced series resistance loss by the half-cell electronic structure and enhanced light absorption by the optical gain structure in the mc-Si photovoltaic modules.
