Session: 15:15

Abstract

Opportunities and challenges for atomic layer deposition in organo-metal halide perovskite solar cells.

Within the class of emerging photovoltaic technologies, organo-metal halide perovskite solar cells have exhibited a sky-rocketing conversion efficiency above 20% in just a few years. This contribution will address the opportunities which atomic layer deposition (ALD) offers to perovskite solar cells by highlighting its merits of low temperature processing and compatibility with 3D-structures.
Specifically, we will present two case studies where (ultra-)thin ALD layers suppress charge carrier recombination processes at the complex interface ITO/mesoscopic TiO2 scaffold/perovskite absorber.
This contribution will include a discussion on the challenges yet to be met by ALD processing directly on the perovskite absorbers or on the organic transport layer. In all these cases, a careful interface engineering needs to take into consideration several aspects ( such as processing temperature, precursor diffusion into the porous hybrid substrate and choice of reactant) potentially affecting the opto-chemical and morphological stability of the components of the perovskite solar cell.
