Bakker, K. (author), Nilsson Ahman, H. (author), Aantjes, K. (author), Barreau, N. (author), Weeber, A.W. (author), Theelen, M. (author)Partial shading of Cu(In,Ga)Se2 modules can lead to the formation of reverse bias induced wormlike defects. These wormlike defects act as local shunts and permanently decrease module output. A good understanding of the formation and propagationmechanisms of these defects is needed in order tomitigate the negative effects, or to prevent these...article 2019

Lametrs, M.W.P.E. (author), Weeber, A.W. (author)The passivating properties of the layer were previously correlated to cell output properties like the open-circuit voltage VOC [1, 2]. Last decade more details about the passivating properties and mechanisms behind it have been elucidated. The bulk passivating properties of a-SiNx:H are related to the release of H from the layer, which diffuses...bookPart 2018

(author)This article presents recent approaches for achieving high conversion efficiency of crystalline silicon solar cells at Delft University of Technology. The new approaches are based on heterojuction interfaces between the crystalline silicon (c-Si) absorber and carrier-selective passivating contact layers.

(author)We present large-area “moly-poly” cells, with a front side MoOx/a-Si:H(i) passivating contact and a rear-side poly-Si/SiOx stack, and we have demonstrated that MoOx based c-Si solar cell technology can be scaled to industrial wafer size. Excellent surface passivation was achieved using MoOx and poly-Si, leading to implied Voc values above 700 mV...conference paper 2018
