Ultrathin polymer layer boosts perovskite solar cell efficiency to 26.39%

A team of solar engineers at Huaqiao University, working with a pair of chemists from the City University of Hong Kong and another colleague from the Chinese Academy of Sciences, has developed an improved perovskite solar cell with 26.39% efficiency. In their study, published in Nature Communications, the group used a hole-selective interlayer that inhibits ion diffusion to improve the device's stability.
