A team of researchers from the National University of Singapore (NUS) has set a new record in the power conversion efficiency of solar cells made using perovskite and organic materials. This technological breakthrough paves the way for flexible, light-weight, low cost and ultra-thin photovoltaic cells which are ideal for powering vehicles, boats, blinds and other applications.

“Technologies for clean and renewable energy are extremely important for carbon reduction. Solar cells that directly convert solar energy into electricity are among the most promising clean energy technologies...

A small guest molecule in the right place makes it possible to produce energy-efficient organic solar cells using eco-friendly solvents. A record efficiency over 17% is demonstrated. In addition, solar cells with larger areas can be produced. “This is a major step towards large-scale industrial manufacture of efficient and stable organic solar cells,” says Feng Gao, professor in the Department of Physics, Chemistry and Biology (IFM) at Linköping University. The result has been published in Nature Energy.

Developments in organic solar cells are rapid, and the maximum energy efficiency achieved by solar cells produced in the laboratory is currently over 18%...
