High-Bandgap Perovskite Materials for Multijunction Solar Cells
Yang, T. C. J.; Fiala, P.; Jeangros, Q.; Ballif, C. (2018)High-bandgap (>1.7 eV) mixed halide perovskites for multijunction solar cells are usually affected by photoinduced phase segregation, which triggers subbandgap defects that are detrimental to the open-circuit voltage. While ... -
I-2 vapor-induced degradation of formamidinium lead iodide based perovskite solar cells under heat-light soaking conditions
Fu, F.; Pisoni, S.; Jeangros, Q.; Sastre-Pellicer, J.; Kawecki, M.; Paracchino, A.; et al. (2019)Over the last years, the operational stability of perovskite solar cells has been significantly improved by compositional engineering, interface modification, and improved encapsulation techniques. However, irreversible ... -
Instability of p-i-n perovskite solar cells under reverse bias
Razera, R.A.Z.; Jacobs, D. A.; Fu, F.; Fiala, P.; Dussouillez, M.; Sahli, F.; Yang, T.C.J.; Ding, L.; Walter, A.; Feil, A. F.; Boudinov, H. I.; Nicolay, S.; Ballif, C.; Jeangros, Q. (2020-01)Partial shading can trigger permanent damage in photovoltaic modules because the illuminated solar cells drive the shaded cells into reverse bias. Under reverse bias conditions, perovskite solar cells have been shown to ... -

Passivating electron contact based on highly crystalline nanostructured silicon oxide layers for silicon solar cells
Stuckelberger, J.; Nogay, G.; Wyss, P.; Jeangros, Q.; Allebe, C.; Debrot, F.; et al. (2016)We present a novel passivating contact structure based on a nanostructured silicon-based layer. Traditional poly-Si junctions feature excellent junction characteristics but their optical absorption induces current losses ... -
Properties of mixed phase silicon-oxide-based passivating contacts for silicon solar cells
Mack, I.; Stuckelberger, J.; Wyss, P.; Nogay, G.; Jeangros, Q.; Horzel, J.; et al. (2018)We investigate the properties of an electron selective front contact based on a phosphorous doped mixed-phase SiOx/Si layer stack at device level. The addition of the SiOx phase to the Si layer targets reduced optical ... -
