As you probably know, using solar panels is a great way to generate electricity with benefits to the environment due to their green energy and lack of emissions when running.
Nowadays, many companies from all around the world are working on new solar technology that could further boost the adoption of renewable energy. In September 2018, startup working with Oxford University called Oxford PV, received $3 million from the U.K. government in order to find new material to make solar cells.
On 25th of December 2018, U.S. company Swift Solar got $7 million to find a technology that can use new materials of solar cells and bring it into the market.
Let’s have a look at the efficiency of solar panels we already have.
According to https://www.greenmatch.co.uk the most efficient are monocrystalline panels (pure silicon) which efficiency stands at 27%.
Perovskite cell – the new photovoltaic tech, uses hybrid organic-inorganic lead or tin halide-based material as the layer. It offers better efficiency in the conversion of light to electric power at a lower cost than existing technologies.
“Perovskite has let us truly rethink what we can do with the silicon-based solar panels we see on roofs today,” said Sam Stranks, one of the co-founders of Swift Solar, in a Ted Talk. “Another aspect that really excites me: how cheaply these can be made. These thin crystalline films are made by mixing two inexpensive readily abundant salts to make an ink that can be deposited in many different ways… This means that perovskite solar panels could cost less than half of their silicon counterparts.”
Perovskite was incorporated into solar cells in 2009 by Japanese researchers but firstly was not efficient and suffered from lacked stability. It means that it wasn’t really used in manufacturing.
Luckily, over the past nine years researchers have improved both the stability and efficiency that these solar cells generate.
Oxford PV is now working on solar cells that could reach the efficiency of conversion at 37%.
I personally think that idea of Perovskite is really promising and deployed into everyday functioning can be a great step into sustainable world.
