Came across this article about Perovskites that I thought i'd share. The future is bright, the future is solar.!!
https://www.theguardian.com/sustainable-business/2015/dec/18/game-changing-perovskite-solar-tech-could-be-cheaper-and-more-efficient“When you start to do the bill of materials analysis, you start to work out that the contacts are just a couple of dollars per square metre in terms of active material costs, which is spectacularly low. So, the panel costs half or less compared to traditional panels.”
Perovskites can also be chemically fine–tuned to change colour and transparency, and they can also be manufactured directly onto other structures, making them attractive for those wanting to integrate solar PV into buildings. For example, solar panels could be placed directly onto glass facades and roller-coated materials, like roofing steel, at the point of manufacture. This could potentially mean greater uptake in solar on large commercial structures, like warehouses. They could also be potentially integrated into energy harvesting and storage systems for household generators.
“Most [solar panels] have to be fitted onto buildings after the fact, which incur extra costs in materials and labour”, Milliken says.
“Perovskites therefore have an extra arrow in the quiver for future expansion opportunities and for achieving things like zero net energy buildings, which will require something like this technology to be integrated into building envelopes.
Yes, it's good news and something that we are factoring into our ElectriCChain predictions.
Basically most glass surfaces that won't be shaded or indoors in the future will be powering something, and, it will be a complex basket of SBIoT (Solar Blockchain IoT).
Perovskites added to the traditional p-n junction have passivation qualities on traditional Silicon cell interfaces as well, improving current production technology's output efficiency.
In addition, the Perovskite cells do stand alone on their own right. They have been around in the industry for over 20+years and organic cells and Perovskite cells have always had visual light and UV-light stability problems. But, this is improving.
I am interested in these, but we won't see a lot of these offshoot technologies in large scale production for 3 to 5+ years out, and some, if ever. But others may evolve separately.
