Homogeneously Blended Donor and Acceptor AgBiS2 Nanocrystal Inks Enable High‐Performance Eco‐Friendly Solar Cells with Enhanced Carrier Diffusion Length (Adv. Energy Mater. 12/2025)

Solar Cells
Surface trap sites in AgBiS2 nanocrystals cause trap-assisted recombination and short diffusion lengths, decreasing power conversion efficiency (PCE) in photovoltaic applications. In article number 2404552, Oh-Hoon Kwon, Jongmin Choi, and co-workers present a donor–acceptor blended solar cell with tailored surface chemistry, which promotes carrier separation, extends carrier lifetime and diffusion lengths, and improves PCE to 8.26%.
