Application of S 2− stabilized CuInS2 nanocrystals in inorganic and hybrid organic/inorganic nanocrystal solar cells — •Christopher Krause, Rany Miranti, Dorothea Scheunemann, Holger Borchert, and Jürgen Parisi — University of Oldenburg, Department of Physics, Energy and Semiconductor Research Laboratory, 26129 Oldenburg
Semiconductor nanocrystals have attracted much attention for application in inorganic/organic hybrid solar cells as well as all-inorganic solar cells during past years. CuInS2 (CIS) nanocrystals are especially promising for solar cell application because of their absorption extending into the near infrared region, providing a suitable overlap with the solar spectrum. The nanocrystals prepared by colloidal synthesis are usually stabilized by long-chained organic molecules hampering the charge transport between adjacent nanocrystals and the charge transfer between donor and acceptor in hybrid devices. To overcome this problem the nanocrystal surface can be exchanged by inorganic ligands, like S 2−-ions. These ligands are small, facilitating charge transport and provide electrostatic stabilization of the colloidal solution. In this contribution I will present the application of S 2− stabilized CIS nanocrystals in inorganic/organic hybrid solar cells as well as all-inorganic nanocrystal solar cells.
