Abstract

The solar power generation market has experienced rapid growth in recent years, with the industry increasingly shifting towards building-integrated solar solutions due to limitations in ground-based installation sites. Building-integrated photovoltaics (BIPVs) have gained attention for their potential to efficiently utilize land resources and enhance the spatial utilization of buildings. While current BIPV systems primarily focus on utilizing roof surfaces for solar energy generation, exploring building façades (vertical surfaces) for solar power generation is essential for future advancements. To address this challenge, a novel approach is required to reduce the weight of conventional silicon solar modules. This study aimed to design, manufacture, and demonstrate thin-film solar modules that are lightweight and flexible for attachment to building exteriors. The manufactured thin-film solar modules had a conversion efficiency of 13.8% and achieved technical completeness by obtaining KS certification (KS C 8562) for thin-film solar modules. A demonstration study of a curved roof solar module was conducted to verify the performance and applicability of curved thin-film solar modules. The demonstration system had a capacity of 7.36 kWp, and its output was analyzed over 27 months. During this period, the monthly average capacity factor was 15%, demonstrating superior results compared with the utilization rate in the same region.
