Moorfield LTE cells used in next generation solar cell research

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.
