摘要：
In order to improve the practicability of PV/T solar system, we proposed the theory and method on the application of diffuse-reflection concentrator in the PV/T solar system and analyzed the concentration characteristics of this proposed application. In addition, we designed experimental prototype of PV/T solar system and conducted test and analysis of the thermal and electrical characteristics of the PV/T solar system with or without a concentrator, respectively. The results showed that for the PV/T solar system with diffuse-reflection concentrator, the amount of incident irradiance was increased by an average of 26% during test period, and the 200-L water in the system was heated to 58 degrees C, which was 12 degrees C higher than that of PV/T solar system without diffuse-reflection concentrator; moreover, the max output power was increased by 11%. Therefore, it is a feasible way to improve the practicability of PT/V solar system by integrating a diffuse-reflection concentrator. Copyright (C) 2016 John Wiley & Sons, Ltd.
