N-type molybdenum diselenide-based liquid junction solar cells: a non-aqueous electrolyte system employing the chlorine/chloride couple. Technical report
Abstract
Single crystal, n-type MoSe/sub 2/ is shown to serve as a stable photoanode in an electrochemical cell employing a nonaqueous (CH/sub 3/CN) solution of Cl/sub 2//Cl/sup -/ as the redox active material. The photoanode reaction is 2Cl/sup -/ Cl/sub 2/ and the cathode reaction is Cl/sub 2/ 2Cl/sup -/. The MoSe/sub 2/ is qualitatively beter than MoS/sub 2/ (0.5% efficiency) which has a larger band gap (1.7 eV), but both materials are rugged in the nonaqueous solution while both photocorrode in aqueous Cl(-) solutions. In H/sub 2/O, the I/sub 3//sup -/I/sup -/ couple is excellent but in CH/sub 3/CN it yields lower efficiency than the Cl/sub 2//Cl/sup -// couple. The stable Cl2(-)/Cl(-) system provides evidence that a transparent, reversible, non-0/sub 2/ sensitive redox couple can be useful in n-type semiconductor-based liquid junction cells employing a direct band gap material having optimum solar response.
