Polymer - CuInS2 hybrid solar cells obtained by an in-situ formation route

Bulk heterojunction hybrid solar cells with a CuInS₂-poly(p-phenylene vinylene) active layer are presented in this contribution. The acceptor phase is obtained in-situ within the matrix of the polymer by the reaction of the metal ions with the decomposition products of a sulfur source (thioacetamide) using a moderate heating step. As prepared donor-acceptor nanocomposites were used as active layers in hybrid solar cells. Structural characterization was performed using XRD and TEM methods, solar cell performance and optical properties were explored by j-V-, absorbance- and IPCE-measurements.
