A novel MoS₂-based hybrid film as the back electrode for high-performance thin film solar cells

Abstract

A MoS2-based complex film was developed with a high work function and thickness-dependent conductivity, which greatly improved the CdTe cell efficiency.

CdTe Photovoltaics in Superstrate Geometry–Back-Contact Materials: A Review

“…The sulfides and selenides have similar chemical properties, which will form several stable metallic compounds like VSe 2 , NbSe 2 , Cu 2 S, FeS 2 , MoS 2 , etc. Many of these materials are tried as back contact materials and provide a result similar to tellurides in CdTe solar cells.…”

“…Yuan et al detailed the usage of MoS 2 as a back contact material for CdTe-based solar cells. 132 The work explains a hybrid deposition technique of MoS 2 dissolved in N-methyl-2pyrrolidone. The advantage of MoS 2 is that its electronic structure, band gap, and work function can be easily tuned.…”

Synthesis and Characterization of Samarium-Substituted Molybdenum Diselenide and Its Graphene Oxide Nanohybrid for Enhancing the Selective Sensing of Chloramphenicol in a Milk Sample

“…Both MoS 2 and MoSe 2 possess a sandwich structure consisting of one Mo covalently bonded with two chalcogen atoms (S or Se), and each monolayer is attracted by weak forces. The layered structure with predominant catalytic active sites offers superior electrochemical properties. , MoSe 2 potentially exhibits electrocatalytic reaction and specific conductance superior to MoS 2 owing to the 20 order greater metallic conductivity and the more functional unsaturated sites of Se, attractive volumetric energy density, faster electrochemical reaction rate, higher metallic binding with transition metals, larger atomic size, and polarizability. − These emerging properties of MoSe 2 make it extremely useful for various electrochemical applications. − Currently, different methods have been explored to enrich the electrocatalytic reaction of MoSe 2 . For this purpose, different strategies have been developed and followed such as (i) creating the atomic lattice distortion or defect through the introduction of the electropositive cation with heterogeneous spin states and (ii) the integration of carbon conductive materials with abundant active sites.…”
