Our planet is facing an extremely difficult global crisis due to climate change. To mitigate this line of the task we need fresh and renewable energy innovations.
New discoveries here can make our planet a much better place to live, reduce the deleterious impact of climate change and create a tight rope of a high level of living. Harnessing energy through green and clean methods is the way ahead to protect our civilization.
As Jimmy Carter once said: no-one can ever ban the sun or reduce its delivery to us”; the sun is the most used present to humanity and harnessing sunlight at a cut-rate price will be the solution to our energy demand issues to a great extent.
A perovskite solar cell is a kind of solar cell. This includes a perovskite structured compound, most of which is a commonly a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer.
Perovskite materials, such as methylammonium lead halides and all-inorganic cesium lead halide, are cheap to produce and simple to manufacture.
In the past few years, the PV sector has undergone a surge of installments and severe price reduction; however, the creation of silicon solar cells remains a highly energy-intensive process – that is, the energy taken in to produce the technology – the energy payback time – stays high, and the production rate is not capable to change quickly to the challenges of catering to the future demand.
But today the latest breed of solar technology could prove to be the solution. The old school silicon-based solar cells are presently mature, or first-generation, technology.
They were taken in by fine film-based PV cells; these are created by installing thin layers of a light-harvesting material on a substrate, which can be glass, metal or plastic.
This process uses vibrant materials in highly fine layers, however, which makes it a demanding task to be competitive with respect to its pricing as opposed to the classical silicon-based PV cells.
Yes, we are under a cloud of threat that can lead to extinction. It’s worth our panic but that is not to say we don’t have alternatives. We do, so go explore them.
