Abstract

A concentration photovoltaic (CPV) system adopting a liquid crystal light modulation is demonstrated. The LC light modulation adjusts the optical power density of the incident light based on the electrically controllable distribution of LC directors. The electrically tunable concentration ratio of the LC light modulation can help to achieve the highest and a fixed efficiency of the CPV system because the LC light modulation helps to increase the photocurrent at a low illumination and prevent the effect of the series resistance at a high illumination. This study opens a window in solar cells by using LC light modulations.
