Peroskite, a new material for solar cells


In the energy sector, a new way of producing has openedsolar powerincreasingly cheaper. Scientists are studying the Perovskite, a very cheap material and that would be able to capture the sunlight and which in addition would have excellent conductivity. Isolated for the first time in 1839, theperovskiteit would be able to combine energy efficiency, conductivity and economy.

The first prototypes of theperovskite-based solar cells, their efficiency is about 15% and if this percentage may seem low, just think that even lower production prices would be able to make the game. Although there are otherssolar cellswith greater efficiency, those based onperovskiteit'ssolar cellswith the best ratio "efficiency / price“.

Many advantages related to the use ofperovskite-based solar cellsare due to their production: the production processes and the treatment of materials do not require much energy and are quite simple. On the contrary, to manufacture one silicon-based solar cella lot of energy is required combined with very accurate and expensive processing, plus the silicon used in the production ofcells solarit must have a high degree of purity.

The manufacture ofperovskite-based solar cellsinvolves a spray application process: perovskite is placed on a glass sheet or metal substrate, this process is so simple that it can be compared to painting. The solar cell can be worked with so easily, MIT scientists describe it as simple as painting a surface.

Theperovskite-based solar cellsmay finally be able to produce solar energy at a price of 10-20 cents per watt, great if you think that currently thesolar power produced with photovoltaic systems costs 75 cents per watt.
