Public Funding for Greatcell Solar UK Limited

To develop perovskite solar cells with a focus on optimisation of novel deposition and processing methods for flexible plastic (polymer) substrates. The target market is for development of light-weight cells suitable for low-cost building integrated photovoltaic (BIPV) applications.

To develop perovskite solar cells with a focus on developing novel, low-cost charge transport materials, for application on flexible substrates and Building Integrated Photovoltaic products.

This collaborative early stage project focuses on investigating the potential of developing higher efficiency stable perovskite solar cells (PSC) by the improvement of the meso-porous Titania cathode substrate structures by surface treatment processing. Various methods will be utilised to realise the surface treatments and fully processed PSCs will be fabricated and tested to verify the performance and stability benefits. This collaborative R&D project will focus on improving the efficiency, stability and processing of the PSC technology, in order to move towards developing viable and manufacturable thin film PSCs suitable for implementation in the Building Integrated Photovoltaic (BIPV) market. Building on existing perovskite PV material stack technologies; new process methods and the incorporation of improved electronic layers will be explored, developed and tested. The benefits will also include lower cost (<$0.2/ Wh) and an expected improved stability and scalable processing routes for manufacturing. It will secure a UK R&D capability with the key supplier of technology and materials for perovskite solar cells with the support of the HVM Catapult and its facilities.

To develop novel materials and interface engineering for 3rd Generation (perovskite) solid state dye sensitised solar cells
