Analysis of the Aesthetic Improvement and High Efficiency of Color PV Module Based on Dot Pattern

Abstract

The solar energy market in South Korea has shown a high growth rate, with an expectation of reaching 4 GW in 2022. Plans to expand BIPV (Building Integrated Photo Voltaic) when new buildings are created have recently been increasing in preparation for a mandatory zero energy policy. Currently, zero-energy construction is mandatory for public buildings of over 1,000 m 2 . By gradually expanding the scope of the target, the mandatory designation of all buildings of over 500 m 2 as zero-energy buildings is expected to occur by 2030. In this paper, we describe an efficiency optimization study based on the width ratio, coverage rate, and color of the patterns for an aesthetic improvement and high efficiency of the product. We aim to develop 50 W dot-pattern-based color solar modules that can improve the artistry and value of buildings when BIPVs are installed. A commercialization model is needed to expand the BIPV product line, which can add design and functional elements in the domestic solar power market, which is expected to grow at rates of tens of gigawatts in the future.
