Solar cells based on hybrid organic/inorganic perovskites have shown an astonishing efficiency development in the past years, having peaked in power conversion efficiencies of >25% for small-area single-junction devices. To pave the way for future co

One of the key challenges of perovskite photovoltaics (PV) is the long-term stability. Although efforts are made to improve the lifetime of perovskite PV devices, their degradation under reverse-bias conditions is barely addressed. Herein, perovskite

An overshoot of the open-circuit voltage (VOC) after switching off the illumination is observed for perovskite solar cells, while the simultaneously measured photoluminescence (PL) intensity decreases continuously. Similarly, a dip in the photovoltag

In organic photovoltaics, high power conversion efficiencies (PCE) are mostly achieved on device areas well below 0.1 cm2. Herein, organic solar cells based on a D18:Y6 absorber layer on an active area of > 1 cm2 with a certified PCE of 15.24% are re

Light soaking under ""1 sun"" is performed on planar p-i-n perovskite solar cells with a Cs0.05MA0.10FA0.85Pb(I0.95Br0.05)3 absorber while measuring current and voltage transients simultaneously to spectral photoluminescence (PL). From theory a tenfo

Interfacial layers consisting of organic molecules with a permanent dipole moment exhibit enhanced charge carrier selectivity when applied as electron-selective contacts in crystalline silicon (c-Si) heterojunction solar cells. It is found that therm
