The old Edwards e306 evaporators continue to receive upgrades to extend their useful life. This month the University of Cardiff received a turbo pump, dry backing pump, water interlock and fast vent upgrade. Apart from saving 20,000 kWhr per year (that’s about GBP 3,200) the customer can also say goodbye to diffusion and rotary pump oil!
Compared to other photovoltaic technologies, perovskite solar cells are currently showing impressive rates of performance improvement. We take a look at the fabrication process and useful systems for deposition.
