This paper investigates process-induced variations of the open-circuit voltage (Voc) using voltage-dependent quantum efficiency measurements. By means of device modelling we show that this method is able to explain the Voc ...

We examine two different silicon solar cell designs featuring full-area electron-selective contacts based on ultrathin (2-3 nm) titanium oxide (TiOx) films deposited by atomic layer deposition. The first cell design applies ...

Aftera briefreview of therecent evolvement oforganic-silicon heterojunction solar cells,we present here our latest measurements of the saturation current densities (J0) and contact resistances (RC) of crystalline silicon ...

The recent tremendous progress in monolithic perovskite-based double-junction solar cells is just the start of a new era of ultra-high-efficiency multi-junction photovoltaics. We report on triple-junction perovskite-pero ...
