Characterisation of Silicon Heterojunction Solar Cells Beyond Standard Test Conditions
The global photovoltaic market is mostly dominated by solar cells based on crystalline silicon (c-Si), which are covering 95% of the market. This thesis concerns silicon heterojunction (SHJ), a high-efficiency technology with a 2% market share in 2018, but ...
EPFL2020Design Rules to Fully Benefit From Bifaciality in Two-Terminal Perovskite/Silicon Tandem Solar Cells
Christophe Ballif, Quentin Thomas Jeangros, Mathieu Gérard Boccard, Olivier Denis Dupré, Pierre-Jean Alet, Arttu Matias Tuomiranta
The photovoltaics industry is adopting bifacial systems which offer improved energy harvesting compared to monofacial ones. This stems from the collection of light reflected by the surroundings on the rear side of the modules, leading to system-level gains ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2020Prediction of Photocurrent in Bifacial Photovoltaic Systems
Motivated by the shift of the photovoltaic (PV) industry towards bifacial solar modules, desert markets, and ever narrower profit margins, this thesis study is aimed at improving the estimation accuracy of the output of bifacial PV systems that are potenti ...
