Researchers from the CitySolar project announce efficiency record for transparent tandem solar cells
Researchers from the CitySolar project have announced an efficiency record for transparent solar cells. By combining organic solar cells with perovskite-based ones, the scientists were able to achieve an efficiency of 12.3%.
These cells could be used for building-integrated photovoltaics, transforming windows into solar panels. “Transparent solar cells could be the next big step in building-integrated energy solutions,” said Professor Morten Madsen from the University of Southern Denmark, who was one of the key researchers behind the breakthrough. “The large glass facades found in modern office buildings can now be used for energy production without requiring additional space or special structural changes... This represents a massive market opportunity.”
