Perovskites Solar Panel For Green, Clean Energy
The Solar Power has emerged as a clean, green source of energy and almost a pollution free source of energy. It is a self-sufficient, unpolluted and does not produce greenhouse gases. Though the initial cost of infrastructure might be on the higher side it is sure to reduce considerably in the coming years. SAULE Technologies located in Polland is one of the first companies in the world which works on the commercial use of perovskites in the production of ultra-thin and flexible photovoltaic cells. The technology developed used creates new, innovative products and reduces the energy costs. SAULE’s vision is to develop the technology which can integrate perovskites with the existing products.
Saule Technologies have recently this year presented the first working prototype of the photovoltaic module based on perovskites, which can power devices like smartphones. This sure is a huge step in the future of Solar technologies leading the way towards a better and cheaper solar cells.
Perovskites – what are they?
Perovskites named after the Russian mineralogist Lev Perovski, whose colleague Gustav Rose first classified this characteristic arrangement of atoms on the basis of calcium titanate present in the rocks of the Ural Mountains. In the case of Perovskites, the properties are not determined by their composition but by the arrangement of atoms in the structure. Hence, everything that has the same arrangement of atoms as calcium titanate is called perovskite.
There are in general three types of Perovskites –
• Organic : They occur in the nature in the form of Rocks and Magma.
• Inorganic : They are developed in laboratories using chemical synthesis.
• Hybrid : Such types are partially organic and partially inorganic.
Perovskites can absorb a large amount of light and they are produced in the process of chemical synthesis of very cheap starting materials. The Perovskite cells are prepared in a wet chemistry process making it possible to print them on any surface. Perovskite-based solar cells are cheap and perform better than silicon-based technology
Though we cannot make a direct comparison of Perovskites in solar cells with the Silicon cells as perovskite-based cells represent a completely different approach to photovoltaics. It would be like comparing a first electric car with a first steam driven engine. Though both have a steering wheel and can move, yet they differ when it comes to efficiency, simplicity, and grace.
Unlike the bulky Silicon solar panels we have been using traditionally, the unique properties of perovskites will enable us to integrate the solar panels with our glass panes. The windows will become photovoltaic panels while losing very little transparency.
Tiles can be covered with perovskite cells and convert the entire roof into a huge photovoltaic panel. The material is so flexible that binds well making it look no different from a roof covered with ordinary tiles. The use goes a long way where we can use Perovskites to entire facades of a modern building and production halls and not just to the roof and windows but also the walls can produce electricity. It is the flexible nature of Perovskites which maximises the area as compared to the traditional silicon cells. The above-mentioned application is already being worked upon by Saule Technologies.
