DOI: 10.1002/adma.202107729

Abstract: Sn-Pb mixed perovskites with bandgaps in the range of 1.1-1.4 eV are ideal candidates for single-junction solar cells to approach the Shockley-Queisser limit. However, the efficiency and stability of Sn-Pb mixed perovskite solar cells (PSC) still… read more here.

DOI: 10.1002/aelm.202400797

Abstract: While compositional gradient‐induced spin‐current generation is explored, its microscopic mechanisms remain poorly understood. Here, the contribution of polarity of compositional gradient on spin‐current generation is explored. A nanoscale compositional gradient, formed by in situ atomic… read more here.

DOI: 10.1016/j.porgcoat.2019.01.037

Abstract: Abstract A series of ladder-like silsesquioxane and their compositional gradient hybrid coatings with epoxy were fabricated by solution-diffuse technique, which involved pre-curing of epoxy followed by coating the silsesquioxane/tetrahydrofuran solution and then post-curing. The resulting… read more here.
