Tokyo, Japan (SPX) Jun 03, 2026
Researchers have achieved a power conversion efficiency of 20.21 percent in pseudo-planar heterojunction organic solar cells by introducing a crystalline polymer buffer layer that shields against solvent-induced erosion during fabrication.
The study, published in Chinese Journal of Polymer Science, addresses a persistent challenge in layer-by-layer deposition. During application of the top
