Our mission is to go beyond the Detailed Balance limit (33.7%) and explore innovative material, device, and process strategies. Our goal is to approach the thermodynamic limit of 85% efficiency in solar energy conversion.
Through cutting-edge research and development, we are striving to pave the way for highly efficient and sustainable devices towards a brighter and greener future with solar energy.
