 So a breakthrough in perovskite solar cells [is part the solution](https://www.theguardian.com/technology/2014/mar/02/perovskite-lightbulb-moment-abundant-solar-power-britain?CMP=fb_gu) to the 
UK’s longstanding energy shortage. Consequently, Scientists attending the Materials
Research Society conference in Boston, Massachusetts reported back in 2014. Reporting
news of vast improvements in the efficiency of photovoltaics!

So perovskite materials, such as [methylammonium lead halides and](https://en.m.wikipedia.org/wiki/Methylammonium_lead_halide)
all-inorganic cesium lead halide are cheap to produce. As well as they are simple
to manufacture.

[Solar cell efficiencies](https://en.m.wikipedia.org/wiki/Solar_cell_efficiencies)
of devices using these materials increasing from 3.8% in 2009^([[4]](https://en.m.wikipedia.org/wiki/Perovskite_solar_cell#cite_note-ReferenceA-4))
to 25.2% in 2019. All in single-junction architectures,^([[5]](https://en.m.wikipedia.org/wiki/Perovskite_solar_cell#cite_note-NREL_chart-5))
and, in silicon-based tandem cells, to 28.0%,^([[5]](https://en.m.wikipedia.org/wiki/Perovskite_solar_cell#cite_note-NREL_chart-5))
exceeding the maximum efficiency achieved in single-junction silicon solar cells.
Perovskite solar cells are therefore the fastest-advancing solar technology to date.

So nowadays and with the potential of achieving even higher efficiencies. Even with
very low production costs, perovskite solar cells are commercially attractive.

Currently sunlight is converted into electricity through silicon solar cells. Now
it’s an upfront cost that most can not afford to buy. Others are Leasing and community
solar. So recent improvements to perovskite solar cells result in a valid alternative
to silicon. Most noteworthy with the efficiency utilizes the 1% of British sunlight.
All needed to fulfill current energy demands.

Again so back in 2014, speakers at the Rump Session for Organo-metal Halide Perovskite-
based Solar Cells seminar learned. These cells are revealing that size and orientation
of the material’s crystals determine everything in perovskite performance. The findings
collected through X-ray scatterings; research reports stating,

In conclusion, further developments in PV tech are providing a cost-effective source
of British energy. Yes folks and with the efficiency to compete. Finally, it will
override the use of fossil fuels.
