Barrie Yates has brought to our attention new developments in solar power generation….
New generation Solar Cells….
“The subject of saving the planet is very much in our thoughts, and as engineers and scientists we hope to use our skills to help reduce global warming by the use of technology. One development toward this goal is the use of solar panels to generate electricity . At the present these are produced using silicon technology, but currently there is a great deal of interest in the use of modified Perovskite (a naturally occurring mineral) in solar panels. The new technology promises an improvement in performance over silicon cells, but the main hope is much lower production costs. The leaders at the moment are the Chinese who have overcome the technical difficulties in mass producing usable panels.”

What is this mineral ?
Perovskite is a calcium titanium oxide mineral, with the chemical formula CaTiO3. The mineral was discovered in the Ural Mountains of Russia by Gustav Rose in 1839 and is named after Russian mineralogist Lev Perovski (1792–1856).
Is perovskite the future ?
Perovskite solar cells are a type of photovoltaic cell that has shown great promise for use in solar panels. They have a number of advantages over traditional silicon solar cells, including lower cost, higher efficiency, and greater flexibility in their design and production.
Which company produces perovskite ?
Headquartered in Kyoto, Japan, Enecoat Technologies is widely recognised as one of the best perovskite solar cell manufacturers. Barriers to commercialization are the potential environmental impacts of perovskite materials, which are primarily lead-based. As such, alternative materials are also being studied to evaluate, reduce, mitigate, and potentially eliminate toxicity and environmental concerns.
What are the problems with perovskite ?
As mentioned in the University of Edinburgh article, in addition to the stability problems related to UV radiation, oxygen, and moisture, the thermal stability of PSCs also causes a lot of concern. Degradation of the perovskite layer can be brought on by exposure to high temperatures.
