Abstract
This paper proposes a novel PV-Trombe wall system combined with phase-change material, which is named as PV-PCM-Trombe system. The work mainly experimentally studies the effectiveness and characteristics of using phase change materials to improve the overheating problem of PV-Trombe wall in summer. Through experiments, the photoelectric performance of the system using phase-change board surfaces with and without a matte black paint lacquer are compared; moreover, the influence on thermal environment of building is evaluated. The results indicate the PV-PCM-Trombe wall system shows an effective cooling effect on PV cell in both experiments and that the surface lacquer coating treatment of PCM plates affects little the photoelectric performance of the system and can reduce the working temperature of PV cell.

Building-integrated photovoltaic/thermal technology (BIPV/T) is an important technology for using solar energy that generates solar energy photovoltaic power while improving the thermal environment of buildings to efficiently use solar energy
Focusing on the inclination of solar heating wall of regular PV-Trombe wall system being overheated in summer working conditions, based on the feature that the temperature cannot rise during phase-change heating process of PCM, the present work proposes a novel PV-Trombe wall system combined with PCM, i.e., the PV-PCM-Trombe
The results indicate that the absorption coating treatment on the surface of the PCM plates can reduce the working temperature of PV cell
Summary
Building-integrated photovoltaic/thermal technology (BIPV/T) is an important technology for using solar energy that generates solar energy photovoltaic power while improving the thermal environment of buildings to efficiently use solar energy. This can be considered as a significant contribution to the implementation of sustainable development of the energy. Jie et al [2, 3] presented a novel Trombe wall with PV cells (PV-Trombe), which theoretically and experimentally studied the effect of the PV-Trombe system on indoor temperature and electrical efficiency and found that the aesthetic value was much more than that of normal Trombe wall. Hu et al [4] compared and analyzed the annual thermal performance and electric performance of three types of BIPV system, and the result showed that a PV blind-integrated
