摘要:本文设计并研制了一种实用型三谱段太阳模拟器,其光谱匹配可同时调整3个谱段(300~700 nm,700~900 nm,900~1 700 nm)范围的能量,修正后可满足三结砷化镓太阳电池的测试使用要求。本文重点阐述了三谱段太阳模拟器滤光片的设计和氙灯光谱的修正及测试,介绍了太阳模拟器的光机结构。实验表明:三谱段太阳模拟器的光谱匹配满足三结砷化镓太阳电池各子电池的响应电流值。在有效辐照面150 mm×150 mm上,平均辐照度可以达到2个太阳常数(2 730 W/m 2),辐照不均匀度达到±1.77%,辐照不稳定度达到±0.83%,为太阳电池自动分拣系统提供了可靠稳定的平台。Abstract:A practical triple spectrum solar simulator is designed and developed in this paper. The spectral match of this solar simulator can adjust intensity of three spectral bands(300-700 nm, 700-900 nm, 900-1 700 nm), which can meet the test requirement of triple junction GaInP/GaAs/Ge solar cell after spectrum correction. This paper first describes the design of the filter and the process of system spectrum correction and testing, and then introduces the optical system and mechanical structure of the solar simulator. The experiments show that the solar simulator's spectral match meet triple junction GaInP/GaAs/Ge solar cell's response currents. In the effective irradiated surface area of 150 mm×150 mm, the average irradiance reaches 2 730 W/m 2, the irradiance non-uniformity reaches ±1.77%, and the irradiance temporal instability is up to ±0.83%. The solar simulator provides a stable and reliable platform for the solar cell automatic sorting system.
