132720Development of Low Cost Alkaline Solar CellsClosedFeasibility StudiesInnovate UKPhotovoltaic (PV) devices are one of the major green alternatives for low carbon, clean and renewable energy. The conversion efficiency of solar power into electricity using PV technology is currently limited owing to unwanted heat generation and higher production cost. The innovative alkali thin film PV technology (APVs patented by Solaris Photonics) promises to overcome these problems, and its development could meet the essential objective of lower cost electricity generation with higher efficiency (14-30%). The current proposal is focussed on continuing to develop the APV to obtain an optimised functional prototype which delivers high efficiency whilst ensuring durability and long lifetime. The project aims to fabricate high efficiency low-cost pre-industrial prototype alkali PV cells utilising thermal evaporation deposition, switching to an all sputtering manufacturing process in the long term. The proposed APV technology could become highly competitive with the cost of conventionally generated electricity at point of use.
