Henzel, J. (author), Bakker, N.J. (author), Najafi, Mehrdad (author), Zardetto, Valerio (author), Veenstra, Sjoerd (author), Isabella, O. (author), Mazzarella, L. (author), Weeber, A.W. (author), Theelen, Mirjam (author)Nonequal current generation in the cells of a photovoltaic module, e.g., due to partial shading, leads to operation in reverse bias. This quickly causes a significant efficiency loss in perovskite solar cells. We report a more quantitative investigation of the reverse bias degradation. Various small reverse biases (negative voltages) were...journal article 2023

Gelvez Rueda, M.C. (author), Ahlawat, Paramvir (author), Merten, Lena (author), Jahanbakhshi, Farzaneh (author), Mladenović, Marko (author), Hinderhofer, Alexander (author), Dar, M. Ibrahim (author), Li, Yang (author), Grozema, F.C. (author)Layered hybrid perovskites have emerged as a promising alternative to stabilizing hybrid organic–inorganic perovskite materials, which are predominantly based on Ruddlesden-Popper structures. Formamidinium (FA)-based Dion-Jacobson perovskite analogs are developed that feature bifunctional organic spacers separating the hybrid perovskite slabs...journal article 2020

Galagan, Yulia (author), Di Giacomo, Francesco (author), Gorter, Harrie (author), Kirchner, Gerwin (author), de Vries, Ike (author), Andriessen, Ronn (author), Groen, W.A. (author)The feasibility of upscaling the perovskite solar cells technologies to high volume production using roll-to-roll (R2R) slot die coating is demonstrated in this study. Perovskite solar cells are produced by R2R slot die coating on flexible substrates with a width of 30 cm and the web speed of 3–5 m min−1. R2R deposition of the electron transport...journal article 2018

Isabelli, Fabiano (author), Di Giacomo, Francesco (author), Gorter, Harrie (author), Brunetti, Francesca (author), Groen, W.A. (author), Andriessen, Ronn (author), Galagan, Yulia (author)Current laboratory-scale fabrication of perovskite solar cells involves the use of toxic solvents in the different fabrication steps. The aim of this research is to find a nontoxic alternative to chlorobenzene used for the deposition of hole transport material (HTM) spiro-OMeTAD. The initial selection of the solvents compatible with...journal article 2018

(author)Metal halide perovskites are generating enormous excitement for use in solar cells and light-emission applications, but devices still show substantial non-radiative losses. Here, we show that by combining light and atmospheric treatments, we can increase the internal luminescence quantum efficiencies of polycrystalline perovskite films from 1...journal article 2017
