BIPV 태양광모듈의 보색관계를 활용한 실내환경 개선연구

초록

Perovskite solar cells and Dye-Sensitized Solar Cells (DSSCs), which have emerged as promising technologies worldwide, are increasingly recognized as next-generation Building Integrated Photovoltaic (BIPV) solutions. These technologies can enable transparent or translucent designs by leveraging their light transmission properties. However, the inherent light transmittance and color characteristics of perovskite and DSSC modules significantly influence the comfort and emotional stability of indoor environments. These factors are crucial when designing both solar modules and buildings. This study investigated BIPV modules with specific colors to improve the surface reflection and chromaticity characteristics of the transmitted light, using the unique color contrast relationships of the modules. We measured, compared, and analyzed the transmitted light chromaticity coordinates of photovoltaic modules coated with complementary colors, in contrast to traditional photovoltaic modules. The analysis revealed that the chromaticity coordinates of the coated modules improved by more than 10% compared to uncoated modules. Furthermore, the indoor environment exhibited a refinement effect of over 10%. Based on these findings, we propose a design guideline for incorporating complementary colors into photovoltaic modules, accounting for various module sizes and light transmittance levels. This study aims to establish a principle for designing pleasant indoor environments using solar modules, while enhancing the potential of BIPV technology to maximize both energy efficiency and user satisfaction.
