The fate of charge carriers in solar materials investigated by time resolved X-ray and optical spectroscopy

Fabio Giacomo Santomauro

This thesis investigates the photoinduced charge carrier dynamics of TiO2 nanoparticles and CsPbX3 (X = Cl, Br) nanocrystals, by means of ultrafast x-ray absorption spectroscopy (XAS) and transient absorption spectroscopy (TAS). TiO2 is among the most prom ...

Perovskite solar cells with CuSCN hole extraction layers yield stabilized efficiencies greater than 20%

Michael Graetzel, Shaik Mohammed Zakeeruddin, Mohammad Ibrahim Dar, Neha Arora, Norman Pellet

Perovskite solar cells (PSCs) with efficiencies greater than 20% have been realized only with expensive organic hole-transporting materials. We demonstrate PSCs that achieve stabilized efficiencies exceeding 20% with copper(I) thiocyanate (CuSCN) as the ho ...

Review: Progress in solar cells from hydrogenated amorphous silicon

Christophe Ballif, Franz-Josef Haug, Michael Elias Stückelberger, Rémi Biron

Hydrogenated amorphous silicon (alpha-Si:H) has been used for decades doped and as intrinsic absorber layers in thin-film silicon solar cells. Whereas their effiency was improved for a long time by the deposition of higher quality absorber layers, recent i ...
