Abstract

This research presents the static flexible concentrator photovoltaics (Static CPV) systems for electric vehicles (EVs). The CPV system includes solid CPC, 3‐junction solar cells, and a crystalline Si cell. Direct sunlight with an incident angle satisfying the acceptance angle of the solid CPC is focused on the 3‐junction solar cells, while diffuse sunlight is collected by crystalline Si cells. When direct sunlight and diffused sunlight have an incident angle greater than the acceptance angle of the CPC, they will leak out of the solid CPC and be collected by the Si solar cell. This structure allows to manufacture of Static CPV with a geometrical concentration ratio of 4× for 3‐junction cells, The module was designed using the commercial optic simulation software LightTools™, the simulation results show that the module can achieve 25% annual efficiency, moreover, it can be flexible to meet the requirement of car roof application.
