Chinapost South Korea

Overview

South Korea is aggressively pursuing the commercialization of next-generation perovskite solar cells, intensifying development competition with China, the US, and Europe. This technology offers advantages over silicon, being thinner, lighter, and cheaper. A joint team from KAIST and KRICT achieved 25.56% conversion efficiency with long-term stability. Hanwha Q CELLS is also advancing tandem cell development for BIPV and EV applications. Focus is also placed on environmentally friendly manufacturing processes and low-cost electrode materials.

In Depth

Background

As global energy markets accelerate their transition towards renewable sources, the competition in developing next-generation solar cell technologies is intensifying. Perovskite solar cells (PSCs), with their high power conversion efficiency, thin, light, and flexible properties, and potential for low-cost manufacturing, are being pursued as a national strategic priority by countries worldwide. South Korea has also positioned this technology as a future growth engine, actively participating in the technological race for dominance against major players like China, the United States, and Europe.

Key Findings / Results

The South Korean government and research institutions are vigorously promoting the commercialization of perovskite solar cells, with continuous announcements of significant achievements. Notably, a joint research team from the Korea Advanced Institute of Science and Technology (KAIST) and the Korea Research Institute of Chemical Technology (KRICT) reported groundbreaking research: simultaneously achieving a high efficiency of 25.56% and long-term stability in a single-junction perovskite solar cell. This achievement was made possible through optimized perovskite material composition and advancements in interface control technology. In the industrial sector, major solar cell manufacturer Hanwha Q CELLS is actively developing tandem cells, combining perovskite with silicon, aiming for efficiencies approaching 30%. These technologies are anticipated to find diverse applications in areas where conventional silicon solar cells face limitations, such as building facades and windows (BIPV), electric vehicle roofs (EVs), wearable devices, and even aerospace applications. Environmental aspects are also prioritized for commercialization, with a focus on low-environmental-impact thin-film deposition processes and the development of low-cost electrode materials that do not rely on scarce metals.

Technical Significance & Outlook

South Korea’s national focus on perovskite solar cell development has the potential to significantly enhance its competitiveness in the global energy market. The simultaneous achievement of high efficiency and stability by KAIST and KRICT underscores the importance of fundamental research and elevates international technological standards. The involvement of major corporations like Hanwha Q CELLS is crucial for rapidly translating research findings into mass production and accelerating market entry. The diverse application possibilities of perovskite solar cells are expected to create ripple effects across related industries, including construction, automotive, and electronics, generating new market value. However, commercialization requires not only technological maturity but also further reductions in manufacturing costs, assurance of long-term reliability, and the establishment of international certification standards. South Korea’s proactive approach is anticipated to further stimulate international technological competition and serve as a vital driving force in paving the way for perovskite solar cells to become a core technology for a sustainable society.
