South Korean Researchers Develop Electricity-Generating Window

Developers hope to raise sustained efficiency through further research

Researchers at the Korea Advanced Institute of Science and Technology (KAIST), Daejeon, Republic of Korea, and Sumsung SDI Co., Seoul, Republic of Korea, recently announced the development of a window that can be used to generate electric power. The building integrated photovoltaic (BIPV) cells made by coating windows with Sol-Gel material have reached power efficiency of 11% in laboratory tests. Conventional solar panels have a power efficiency around 15%.

The development team hopes to have models ready for commercial use in four to five years. “Sustained efficiency of at least 10% and overall durability need to be reached,” says Bay Byeong-Soo, a professor at KAIST.
