Scientists from NYU Tandon School of Engineering working on organic solar cell materials was able to improve the performance of a non-fullerene organic solar cell, by utilizing a small molecule of a material known as Squaraine as a crystallizing agent. “We added a small molecule that functions as an electron donor by itself and enhances the absorption of the active layer,” explains Tandon Associate Professor André D. Taylor. … The team created a cell which achieved conversion efficiency of more than 10% – something not previously thought possible with a single-junction polymer solar cell.
