Recyclable gold nanocatalysts with controllable morphology are in-situ formed on the solid substrate by a facile ultrasonic spray pyrolysis method. The Au nanoparticles on Mo substrates form spheres, while on Si icosahedra, or after addition of Cu io

ZnO and ZnS nanodots deposited by simple, non-vacuum ultrasonic spray methods, spray pyrolysis and ion layer gas reaction, are used to control the nucleation and thereby the morphology of electrochemically grown ZnO nanorod arrays. The ZnO nanodot de

Ag nanoparticles have attracted interest for plasmonic absorption enhancement of solar cells. For this purpose, well-defined particle sizes and densities as well as very low deposition temperatures are required. Thus, we report here a new spray chemi

Ultra-thin perovskite absorber layers have attracted increasing interest since they are suitable for application in semi-transparent perovskite and tandem solar cells. In this study, size and density controlled plasmonic silver nanoparticles are succ

In this work, we investigate the p–n junction region for two different buffer/Cu(In,Ga)(Se,S)2 (CIGSSe) samples having different conversion efficiencies (the cell with pure In2S3 buffer shows a lower efficiency than the nano-ZnS/In2S3 buffered one)

Single layers and combined layer systems with Cu(In,Ga)(S,Se)2, ZnS-nanodot (nd) and In2S3 layers were investigated by surface photovoltage spectroscopy in the Kelvin-probe arrangement and compared with the open-circuit voltage (VOC) of solar cells.
