【Abstract】 The photovoltaic/thermal(PV/T) technology can provide electricity and thermal energy at the same time,the solar comprehensive utilization efficiency has been greatly improved. However,there still exist some issues such as limited function,low full-spectrum utilization efficiency and limited utilization on the recovered thermal energy. As for the problems of the photovoltaic/thermal(PV/T)technology,we have put forward a series of novel concepts,systems and functions for the solar photovoltaic-thermal/catalytic-purification comprehensive technology. The proposed technology can realize functions of electricity generation,heating and air purification. Also,we have developed a series of solar photovoltaic-thermal/catalytic-purification building integrated systems,which not only further improve the solar comprehensive utilization efficiency and enhance the system functionality,but also improve the indoor thermal environment and air quality. This article has introduced the authors′research in recent years,which includes the research on photo/thermal-catalytic Trombe wall,photo/thermal-catalytic PV/T-Trombe wall,photo/thermal-catalytic photovoltaic ventilation window and air-purification-sterilization type PV-Trombe wall. The present works have broadened the research and application of building-integrated photovoltaic/thermal technology and provided the new methods on realizing the highly efficient and multi-functional utilization on solar energy in buildings and creating a healthy and comfortable indoor environment.更多还原
