NU Researchers Use Liquid Crystals to Scale-up Perovskite Solar Cells

Researchers create a technique that led to improved efficiency for large-area perovskite solar modules

Organic-inorganic hybrid perovskite solar cells (PSCs) have shown promise to produce renewable solar energy. In small samples, they have achieved a solar energy-to-power conversion efficiency of 26 percent. Scaling up to allow PSCs to produce power on a larger scale, however, has been a challenge due to defects that arise from how the solutions are processed. To combat this, a team led by Northwestern Chemistry and Northwestern Engineering researchers has developed a method that moves PSCs cl...
