title: Improvement in Open-Circuit Voltage of Thin Film Solar Cells from Aqueous Nanocrystals by Interface Engineering.
abstract: In this work, improved solar cells from aqueous CdTe NCs is achieved by replacing evaporated MoOx with spiro-OMeTAD as a hole transfer layer. The increased Voc and Jsc can be attributed to interfacial dipole effect and reduced back recombination loss, respectively. A high PCE of 6.56% for solar cells from aqueous NCs is obtained by optimizing the microstructure further.
