Abstract

Atmospheric pressure plasma enhanced CVD (AP PECVD) systems have attracted considerable interest
in recent years due to the significant benefits for large area, low cost substrates and low temperature
operation. In this work we describe the use of a bespoke roll to roll AP PECVD process to produce large
area, functional TiO2-x films for use as hole blocking electron transport layers in perovskite solar cell
architectures, a critical component typically produced by spin coating or vacuum based technologies.
The AP PECVD produced films can be used to construct cells with overall efficiencies greater than from
the sputtered reference material (13.57 vs. 13.15% maximum power point for 1 cm2 cells). Discussion of
the cell properties suggests scope for further optimisation, maximising the potential of this approach.
