Simulation on reflection plate angles of the efficient black silicon PV modules

Abstract

In order to achieve maximum power output, common PV modules will deliberately make a certain angle, but still some light will be reflected from the surface of the common PV modules into the air and waste. This paper presents a reflective plate structure having efficient black silicon solar modules, and multi-angle light-absorbing black silicon components to construct a reflective plate structure that can take advantage of the reflected light. The angle between the reflectors and black silicon component was simulated in this paper, which shows that when the assembly angle of PV module is 34°, the optimum angle of the reflective plate is 16.5°, in this case, the battery’s power generation is increased by about 39% under the same illumination conditions.
