Investigation of bulk hybrid heterojunction solar cells based on Cu(In,Ga)Se(2) nanocrystals

This work presents the systematic studies of bulk hybrid heterojunction solar cells based on Cu(In, Ga)Se(2) (CIGS) nanocrystals (NCs) embedded in poly(3-hexylthiophene) matrix.

Sumario:This work presents the systematic studies of bulk hybrid heterojunction solar cells based on Cu(In, Ga)Se(2) (CIGS) nanocrystals (NCs) embedded in poly(3-hexylthiophene) matrix. The CIGS NCs of approximately 17 nm in diameter were homogeneously blended with P3HT layer to form an active layer of a photovoltaic device. The blend ratios of CIGS NCs to P3HT, solvent effects on thin film morphologies, interface between P3HT/CIGS NCs and post-production annealing of devices were investigated, and the best performance of photovoltaic devices was measured under AM 1.5 simulated solar illumination (100 mW/cm(2)).
