| Abstract |
The purpose of this study is to review the plan to contribute to the applicability and distribution policy of zero energy building (ZEB) through the design, manufacture, and performance analysis of solar cell integrated LED(Light Emitting Diode) convergence module that combines solar power generation technology and RGB LED display technology. The module design was verified under various environmental conditions by convergence IBC (Interdigitized Back Contact) half-cut solar cell and RGB LED device based on a printed circuit board (PCB) to minimize electrical loss and install transparent glass and color glass, respectively. The photovoltaic performance of the manufactured prototype was evaluated and analyzed according to the KSC IEC 61215 standard, and the maximum output (Pmax) was measured as 46.52W. The LED display performance was analyzed as white luminance 628.4cd/m² and green luminance 415.8cd/m², indicating appropriate luminance and uniform color expression. Through I-V curve analysis, it was confirmed that stable power output is possible in MPPT (Maximum Power Point Tracking). In addition, as a result of analyzing the luminance of LED displays from a light pollution perspective, high-brightness white light and green light may act as potential light pollution factors, but to alleviate this, improvement measures such as automatic dimming control, time schedules management for lighting, and light distribution design were proposed. This research examined that the convergence module can increase the energy independence rate of zero-energy buildings and provide a technical and economic basis for the spread of ZEB in Korea. Future research should focus on the module’s energy efficiency optimization and specific application of light pollution reduction technology. |
