A breakthrough in perovskite solar cells could be the solution to the UK’s longstanding energy shortage. Scientists attending the Materials Research Society conference in Boston, Massachusetts last December were treated to news of vast improvements in the efficiency of photovoltaics.

Currently sunlight is converted into electricity through silicon solar cells which are not only expensive but perform at a low rate of conductivity. The recent improvements to perovskite solar cells could result in a valid alternative to silicon with the efficiency to utilise the 1% of British sunlight needed to fulfil current energy demands.

Speakers at the Rump Session for Organo-metal Halide Perovskite-based Solar Cells revealed that size and orientation of the material’s crystals will determine future developments of perovskite performance. The findings were collected through X-ray scatterings, the research reports stating, “Our findings underscored the importance of full characterizing and controlling the nanostructured components for improved solar cell efficiency.”

With further developments in large-scale conversion, developments in photovoltaic technologies could provide a cost-effective source of British energy with the efficiency to compete and even override the use of fossil fuels.
