Here, we demonstrate the fabrication procedure of the SnS solar cells employing atomic layer deposition, which yields 4.36% certified power conversion efficiency, and thermal evaporation which yields 3.88%.

Direct Comparison of Highly Efficient Solution- and Vacuum-processed Organic Solar Cells Based on Merocyanine Dyes Advanced Materials (Deerfield Beach, Fla.). Oct, 2010 | Pubmed ID: 20512818 Identically configured bulk heterojunction organic solar cells based on merocyanine dye donor and fullerene acceptor compounds (see figure) are manufactured either from solution or by vacuum deposition, to enable a direct comparison. Whereas the former approach is more suitable for screening purposes, the latter approach affords higher short-circuit current density and power conversion efficiency.
3.88% Efficient Tin Sulfide Solar Cells Using Congruent Thermal Evaporation Advanced Materials (Deerfield Beach, Fla.). Nov, 2014 | Pubmed ID: 25142203 Tin sulfide (SnS), as a promising absorber material in thin-film photovoltaic devices, is described. Here, it is confirmed that SnS evaporates congruently, which provides facile composition control akin to cadmium telluride. A SnS heterojunction solar cell is demons trated, which has a power conversion efficiency of 3.88% (certified), and an empirical loss analysis is presented to guide further performance improvements.
