We are delighted to announce that the 12th Sungkyun International Solar Forum (SISF2024) will take place at the 600^th Anniversary Hall, Sungkyunkwan University (SKKU), in Seoul, Korea, from October 30 (Wednesday) to November 1 (Friday), 2024. SISF2024 marks the 12th edition of the forum, with the previous event in 2015 being cancelled due to MERS and the 2020-2021 event being delayed due to the COVID-19 outbreak. The organizing committee is honored to extend an invitation to renowned scientists from around the world to participate in SISF2024. The forum will feature in-depth discussions on recent advances and hot topics in photovoltaics, light-emitting diodes, hydrogen, and optoelectronics based on halide perovskite. Since its inception in 2011, SISF has been held annually on the SKKU campus. With the exception of the first SISF in 2011, the 600th Anniversary Hall at SKKU in Seoul has been designated as the venue for the forum.
