Leaders in perovskite solar technology. Our low-cost, highly efficient photovoltaic technology integrates with standard silicon solar cells to dramatically improve their performance. Built into solar panels, our tandem solar cells deliver more power per square metre - critical for delivering more affordable clean energy, accelerating the adoption rate of solar, and addressing climate change.

Growth, Characterisation and Application of Ultra-Thin Templated Ferroelectric TiO2 Thin Films as Novel Photocatalytic SurfacesAbstractThe lattice parameters between (110) NdGaO3 and the anatase phase of TiO2 are notably close allowing for a lattice mismatch between the substrate and thin film. This offset causes a strain in the crystallinity of anatase on NdGaO3 which has recently been suggested by Deepak, N. et al to induce a ferroelectric effect in films that they fabricated by liquid injection chemical vapour deposition (LI-CVD). The primary aim of this study was to explore this theory and see if such effects could be reproduced and then extended to an atomic layer deposition (ALD) process. A secondary aim was to investigate if the photocatalytic properties of titania are influenced by any ferroelectric properties observed.
