Recently, PhD student Ben Putland supervised by Prof. Henry Snaith (Optoelectronic and Photovoltaic Device Group, University of Oxford) used Moorfield’s low-temperature evaporation (LTE) sources and technology for cutting-edge research into the vacuum deposition synthesis and photovoltaic performance of a novel inorganic lead-free halide solar absorber with the general formula A2BB’X 6.
Being entirely inorganic, this material could be much more stable than organic-based competitors. Furthermore, modelling suggests it could complement existing Si-based technology for forming tandem cells with efficiencies in excess of 30%!
Studies are currently preliminary and ongoing, but early results are encouraging, we can’t wait to see what comes next.
