An international research group has created a closed-loop, transparent energy platform based on PV power generation and hydrogen production from photo-electrochemical cells. The system is claimed to supply power without interruption and to be transparent enough to be integrated into buildings. January 6, 2022 Emiliano BelliniA Korean-U.S. research group has created a system to produce and store green hydrogen via transparent PV (TPV) cells and transparent photo-electrochemical (TPEC) cells that could be integrated into buildings. “We proposed a transparent, sustainable energy platform,” the research’s corresponding author, Joondong Kim, told pv magazine. “Our proposed system benefits the levelized cost of solar hydrogen by on site production and building integration and offers affordable solar hydrogen for domestic applications.” The system is claimed to have a high average…
