Closing the Cell-to-Module Efficiency Gap: A Fully Laser Scribed Perovskite Minimodule With 16% Steady-State Aperture Area Efficiency

Autor: Aldo Di Carlo, Babak Taheri, Christophe Ballif, Fabio Matteocci, Davide Sacchetto, Julien Bailat, Soo-Jin Moon, Arnaud Walter, Linus Lofgren, Brett A. Kamino, Sylvain Nicolay

Publikováno v: IEEE Journal of Photovoltaics

Organic–inorganic halide perovskite solar cells show increasing power conversion efficiencies, approaching the values of silicon-based devices. To date, however, most of the reported record efficiencies for perovskite solar devices are obtained on

Improving low pressure chemical vapor deposited zinc oxide contacts for thin film silicon solar cells by using rough glass substrates

Autor: Johannes Meier, G. Monteduro, M. Marmelo, Jérôme Steinhauser, E. Omnes, Evelyne Vallat-Sauvain, S. Benagli, J.-B. Orhan, J.-F. Boucher, Julien Bailat, B. Wolf, Daniel Borrello, Ulrich Kroll

Publikováno v: Thin Solid Films. 520:1218-1222

Compared to zinc oxide grown (ZnO) on flat glass, rough etched glass substrates decrease the sheet resistance ( R sq ) of zinc oxide layers grown on it. We explain this R sq reduction from a higher thickness and an improved electron mobility for ZnO
