New Quantum Dot Technology Improves Solar Cell Efficiency

A new development in solar technology uses pulse-shaped light to enhance the efficiency of PbS quantum dot solar cells, promising easier production and broader application.
A research team headed by Professor Jongmin Choi from the Department of Energy Science and Engineering at Daegu Gyeongbuk Institute of Science and Technology has successfully developed a “PbS quantum dot” capable of quickly improving the electrical conductivity of solar cells. This collaborative effort involved Professor Changyong Lim of the Department of Energy Chemical Engineering at Kyungpook National University, led by President Wonhwa Hong, and Professor Jongchul Lim from the Department of Energy Engineering at Chungnam National University, under the leadership of President Jeongkyoum Kim.
