Solar Cell

In the times over the conventional sources of energy have risen due to their non-renewable nature, sources such as solar energy are the future of the energy economics.

Solar researchers have devised an ingenious method to make spray-on solar cells a reality in the near future. One of the major drawbacks that the solar energy suffers even today is the high first-cost associated with the installation of the silicon solar panels for the harvesting the solar energy. This new wonder material, called as perovskites, made by the researchers has the property that would enable it to capture the solar irradiation when deposited over a surface and is made to crystallize. Perovskites has been around for a while and the first time its usefulness in the solar energy domain was acknowledge, it was by Tsutomu Miyasaka in the year 2006 at the Toin University of Yokohama.

Due to the cost factor associated with the currently used solar panels the technology has not yet seen the widespread use even though the entire solar power industry is worth $42 billion. Perovskites, on the other hand, would bring down the cost factor as they can be used in a liquid solution form to be deposited over surfaces such as window panes, windows of tall standing buildings, atop vehicles, etc. This technology has been selected by the World Economic Forum as one of the top 10 emerging technologies in the world, and the commercial variant of this incredible new technology could be available by the end of 2018 or so.

Even though this technology has been tipped to be a game changer in the field of solar energy and its applications, there are also groups in the scientific community who are skeptic about its scope of utility. One of the drawbacks that Perovskites suffer from is the fast degradation that they undergo as a result of being used. For a wider and commercial acceptance of this technology, research is being done to understand the crystal lattice of the material and also to come up with techniques that could make it more stable and hence more fit for commercial use.
