(author), Poodt, P. (author), Geerligs, L.J. (author), Aernouts, T. (author), Veenstra, S. (author), Andriessen, H.A.J.M. (author)The purpose of the work is to investigate high-efficient and stable 4-terminal perovskite/c-Si tandem devices. Hybrid tandems of c-Si bottom cells and perovskite top cells are perhaps the most promising candidates to reduce the levelized cost of electricity by increasing the overall tandem cell efficiency. To turn this promise in a commercial...conference paper 2018

Angmo, D. (author), Sweelssen, J. (author), Andriessen, H.A.J.M. (author), Galagan, Y.O. (author), Krebs, F.C. (author)Evaporation is the most commonly used deposition method in the processing of back electrodes in polymer solar cells used in scientifi c studies. However, vacuum-based methods such as evaporation are uneconomical in the upscaling of polymer solar cells as they are throughput limiting steps in an otherwise fast roll-to-roll production line. In...article 2013
