New solar cells based on perovskite have recently been produced in Japan, with fantastic efficiency. Unfortunately, they are not weatherproof, but research is being done into this, it was said. Science expert Christian Mähr from ‘Krone’ thinks that there are more important research goals: namely a large and cheap electricity storage system.
Having followed the subject for a while, I can easily deal with the disappointment this report from Japan has caused regarding weather resistance. I’m kind of used to it. These types of messages already existed in the 1970s, but then the conventional silicon cell continued to exist. Who cares, not that important. In my humble opinion, we do not need new types of solar cells. The ones we have are good enough. High returns are an argument if the cells are just as expensive as before: between extremely expensive and unaffordable. They are now so cheap that the cost of inverters, mounting, wiring, etc. exceeds the cost of the cells themselves. But what we need is a big, cheap battery.
