Abstract: The PV/T (photovoltaic/thermal) system is an efficient method for the comprehensive utilization of solar energy resources. In this paper, a variety of integrated methods of LCPV/T (low concentration photovoltaic/thermal) with compound parabolic concentrator are proposed, and a comparative study was conducted under the same experimental conditions. The design used in this paper focused in two directions: battery and flow channel. In battery direction, this paper changes the physics structure of the battery to improve the electrical efficiency under low concentration. In channel types, three kinds of channel including the aluminum channel, glass channel, and heat pipe module are proposed and analyzed. According to the experimental results, the electrical efficiency of slice battery improved by 8–10% compared to those of ordinary silicon battery under low concentration; aluminum channel showed excellent comprehensive performance, while glass channel exhibited outstanding thermal performance with the expense of some electrical performance, and heat pipe module owned the most uniformity of component’s temperature. All the three designs showed strong specificity in selection.
