Sommeling, P.M. (author), Liu, J. (author), Kroon, J.M. (author)This study addresses the influence of different encapsulation materials on performance losses in bifacial PV modules after extended damp heat testing. The widely used ethylene vinyl acetate (EVA) is compared to polyolefin elastomers (POE) and thermoplastic polyolefins (TPO). We show that modules based on n-type bifacial solar cells (tunnel oxide...article 2023

Slot, H.J. (author), Kroon, J.M. (author)De zee biedt zeeën van ruimte. Grootschalige zonne-energiesystemen op zee bestaan nog niet. Toch kan Nederland vrijwel geheel duurzaam aan zijn energie komen door slechts 5-10% van de oppervlakte van de Noordzee te gebruiken voor zonne-energie. Het doel van het project is om op pilot schaal de technologie te demonstreren die de opwekking van...report 2022

Sommeling, P.M. (author), Liu, J. (author), Kroon, J.M. (author)The IEC 61215 standard for PV modules requires a damp heat (DH) test (1000 h at 85°C, 85 % relative humidity). To have a better alignment with field observations extended and/or sequential testing protocols have been proposed, which involves for DH test a longer testing time under the same conditions. In this study small sized bifacial PV...conference paper 2020

Accurate models for the calculation of the yearly yield can be very detailed and require many parameters. The parameters of these models are often difficult to determine. Simple models are often not very accurate. In this paper, a method...conference paper 2015
