Solution-processed heterojunction solar cells based on p-type PbS quantum dots and n-type Bi <inf>2</inf>S <inf>3</inf> Nanocrystals

Abstract:

Bi 2S 3 nanocrystals are employed as an n-type, non-toxic, inorganic, solution-processed semiconductor in thin film solar cells. The first solution processed-inorganic p-n junction based on p-type PbS QDs and n-type Bi 2S 3 nanocrystals with both phases contributing to photocarrier generation is demonstrated. The reported devices show a power conversion efficiency of 1.6% for 860 nm PbS QDs and over 1% for 1300 nm PbS QDs. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
