Thin, flexible, and efficient silicon solar cells would revolutionize the photovoltaic market and open up new opportunities for PV integration. However, as an indirect semiconductor, silicon exhibits weak absorption for infrared photons and the efficient absorption of the full above bandgap solar spectrum requires careful photon management. This review paper provides an overview on the fundamental physics of light trapping and explains known theoretical limits. Technologies that have been developed to improve light trapping will be discussed, and limitations will be addressed.

薄硅太阳能电池中的光捕获：基本原理和技术综述

薄、灵活、高效的硅太阳能电池将彻底改变光伏市场并为光伏集成开辟新的机遇。然而，作为一种间接半导体，硅对红外光子表现出弱吸收，并且完全高于带隙太阳光谱的有效吸收需要仔细的光子管理。这篇综述论文概述了光捕获的基本物理学，并解释了已知的理论限制。将讨论为改善光捕获而开发的技术，并解决限制问题。
