Abstract

In this study, photovoltaic performance enhancement of single-junction GaAs solar cells using a spectral conversion layer incorporated with luminescent down-shifting (LDS) and up conversion (UC) phosphor-species is experimental demonstrated. The photo-luminescent wavelengths of proposed LDS- and UC-phosphor species are 512 nm and 650-660 nm, respectively. Optical reflectance and external quantum efficiency response are used to examine LDS and UC effects. The performance enhancements are confirmed by photovoltaic current density-voltage curves under AM 1.5G solar simulation. An impressive increasing in absolute efficiency of 0.91% (from 22.92% to 23.83%) was obtained when the cell coated with a spectral conversion layer incorporated with LDS and up UC phosphor-species, compared to the reference cell efficiency of 22.92%t.

在单结砷化镓太阳能电池上加入LDS和UC荧光粉的光谱转换层以提高光伏性能

在本研究中，实验证明了使用含有发光下移(LDS)和上转换(UC)磷的光谱转换层来增强单结砷化镓太阳能电池的光伏性能。LDS-和uc -荧光粉的光致发光波长分别为512 nm和650-660 nm。光反射率和外量子效率响应用于检测LDS和UC效应。在AM 1.5G太阳能模拟下，光伏电流密度-电压曲线证实了性能的增强。与参比电池22.92%的绝对效率相比，包覆LDS和UC的光谱转换层的电池绝对效率提高了0.91%(从22.92%提高到23.83%)。
