Design and Control of Photovoltaic Curtain Wall Based on Compound Parabolic Concentrator

A solar curtain wall modular structure based on compound parabolic concentrator was designed. It can be widely applied to the exterior surface of modern urban buildings, providing a solution integrating the natural lighting, heat insulation and solar power generation. Compared with the traditional photovoltaic curtain wall, the proposed structure can reduce the use area of photovoltaic panels by 64%. With comprehensive consideration of the modular design concept and actual life needs, a series of modules with different functions and the overall framework were proposed. As such, the working mode can be adjusted independently according to the environment to ensure normal working temperature of photovoltaic panels and avoid overheating of building walls. Users can check its working conditions through APP, and adjust its working mode in real time by voice.
