Photovoltaic windows as a new type of exterior window, while satisfying the indoor lighting demand but also generating clean electricity for building use, so in the field of building energy conservation has been widely valued. This paper presents the main classifications of semi-transparent photovoltaic window, analyzes the main factors affecting the heat transfer performance, natural lighting performance, power generation performance and comprehensive economic benefits of translucent photovoltaic windows. The current research of scholars at home and abroad is sorted out and analyzed, and put forward some existing problems. ThenSonStheSbaseSofSthese, to optimize the performance of photovoltaic window and maximize the potential of comprehensive energy saving and economic benefit, this paper puts forward some effective suggestions for the rational design and further optimization of the system.
