Perovskite Power Cells Could Revolutionize the Solar Energy Market
The solar energy market is soon to be radically revolutionised thanks to new research that will see to the harvesting of perovskite solar cells. Scientists are overly excited by this because these cells are not only simple to produce but are also low-cost.
This doesn’t compromise with their efficiency either, the cells are highly effective at changing the sun rays to electricity. These factors when combined will go a long way to boost commercial enterprises that rely on alternative energy solutions.
Professor Aron Walsh leader of the Materials Design Group has tried to shed some light on this new development. He believes that “Hybrid perovskites are an exciting development for solar energy research. The field is rapidly progressing, but the devices have been developing faster than our fundamental understanding of how they work."
Perovskites imitate a crystal structure in a natural mineral discovered in Russia in 1839 called ‘perovskite’; this is achieved through both organic and inorganic chemistry. UK’s largest supercomputer has helped researchers at Bath to imitate the chemical down to the actual properties of its matter.
Frederico Brivio in Physical Review B’s first publication as part of Bath’s DESTINY Initial Training explains why these cells are capable of absorbing such intense sunlight. He reveals that the quantum mechanical interaction between the electrons and their swift movement in this matter boost their level of absorbing the sunlight.
Dr Jarvist Frost comes up with the second publication as part of an EPSRC energy matter consortium in Nano Letters, outlines the system that the matter produce electricity through the sunlight. This varies from previous solar cells mostly because of lack of organic molecules in these perovskite minerals.
Pundits believe that harvesting 1% of the sunlight and turning it into electricity in the UK would be enough to cater to the current energy demands. This also comes as a relief to the environment which faces contamination while harvesting and transporting alternative fuels.
Recent studies insinuate that efficiencies of 20% can be achieved by utilizing these new solar cells using perovskites. Such an innovation through this technology is bound to boost solar energy in the UK which will easily compete with fossil fuels that are currently favourable.
Existing commercial silicon solar cells will soon get a run for their money from this innovation. This is because perovskitespromise high efficiencies of solar energy which will be produced at a lower cost and in large quantities than their predecessor.
