Fabrication and properties of a glass-lens, static-concentrator mini-module

摘要

A glass-lens, static-concentrator mini-module was fabricated by attaching a co-molded glass-lens on a conventional superstrate flat-plate module. Its properties were investigated under simulated and real sunlight conditions. The effect of rear reflection on optical concentration was investigated for the static concentrator mini-modules with white, black and transparent rear Tedlar films. Under a solar simulator condition, optical concentration ratios of 2.05, 1.75 and 1.70 were obtained for the white, transparent and black films. From outdoor and also indoor measurements, the mini-module with the white Tedlar showed the highest maximum output power throughout daytime
