Abstract
Compared to zinc oxide grown (ZnO) on flat glass, rough etched glass substrates decrease the sheet resistance (Rsq) of zinc oxide layers grown on it. We explain this Rsq reduction from a higher thickness and an improved electron mobility for ZnO layers deposited on rough etched glass substrates. When using this etched glass substrate, we also obtain a large variety of surface texture by changing the thickness of the ZnO layer grown on it. This new combination of etched glass and ZnO layer shows improved light trapping potential compared to ZnO films grown on flat glass. With this new approach, Micromorph thin film silicon tandem solar cells with high total current densities (sum of the top and bottom cell current density) of up to 26.8 mA cm− 2 were fabricated.
