Solar photovoltaic technology has demonstrated a strong viability over the last 20 years or so. A significant improvement of the energy conversion efficiency from around 15% to 25% of commercial solar cells combined with the steep module price down from $4/Wp to $0.30/Wp made possible the annual installation of >100 GWp globally. Korea was an underdog in PV in terms of the technology level and the industry capacity up to 2000. The Korea's PV technology level was once estimated about 20 years behind that of the advanced countries such as Japan. Now Korea is one of the world's leading countries in the PV technologies and in the PV industry as well. As an example, Korea's PV scientists lead the world's PV R&D effort in perovskite technology by renewing the efficiency records repeatedly. The Hanwha solution ranks within the global top 5 solar manufacturer and the LG electronics produces solar cells with the highest commercial efficiencies over 24%. Korea is one of the few countries that has the whole PV value chain. Korea is also a leading country in terms of the PV installation. For example, about 4GWp of solar panel was installed in 2020 and the size ranks about 6th globally. This presentation covers the effort of Korea PV communities that made possible the brilliant achievement of today. The future direction of PV community effort will also be discussed.
