New solar cell design with Tetracene boosts efficiency

Researchers from Paderborn University have developed a new design for solar cells that can harness more energy from sunlight than ever before. The key to their innovation is a thin layer of organic material called tetracene that enhances the efficiency of silicon solar cells. Their findings have been published in the journal Physical Review Letters.

A new design for solar cells

According to Prof Dr. Wolf Gero Schmidt, physicist and Dean of the Faculty of Natural Sciences at Paderborn University, solar energy is a huge and largely untapped clean and renewable energy source. He says, “The annual energy of solar radiation on Earth amounts to over one trillion kilowatt-hours and thus exceeds the global energy demand by more than 5,000 times. Photovoltaics, i.e., the generation of electricity from sunlight, therefore offers a large and still largely untapped potential for the supply of clean and renewable energy.”
