Abstract
A method for manufacturing a two terminal or three terminal tandem solar cell with a silicon-based bottom solar cell and a thin-film top solar cell involving: providing a silicon substrate with a front surface and a rear surface, carrying out a sequence of steps including: creating on the front surface a carrier extracting layer stack with at least a carrier extracting layer formed on or in the front surface of the substrate, creating on the rear surface a passivating coating layer with deposition of a first AlOlayer, creating sacrificial layer stack with a second AlOlayer on the carrier extracting layer stack on the front surface; creating metal-based electrical contacts on the rear surface, including an annealing step; removing the sacrificial layer stack from the carrier extracting layer stack, and creating the thin film top solar cell on the carrier extracting layer stack.
