A Study on the Aesthetic BIPV Module with High-efficiency Technology Applied

Abstract

The rapid growth of the building integrated photovoltaics (BIPV) market is attributable to the government’s expansion of BIPV installation support and the policy of raising the REC weight by a factor of 1.5. In addition, as the mandatory, 2025 zero-energy building policy has been extended to the private building sector, interest and demand for BIPV modules and systems are continuously increasing. However, when a general PV module with insufficient aesthetics is installed, it is possible that the installation of BIPV is avoided for aesthetic reasons or installed only at a minimal rate. In other words, to expand the installation and supply of BIPV modules, it is necessary to develop color BIPV modules with aesthetics and high-efficiency technology. In this study, a color BIPV module was developed using polysilazane, which is inexpensive and has excellent transmittance. The electrical output characteristics of the developed color PV module were analyzed, and the output loss was minimized by applying half-cut and gapless processes. In addition, the developed high-efficiency color BIPV module was subjected to an outdoor test, and a commercialization model was established by analyzing the amount of power generated.
