There's lots of excitement about perovskite cells, and hot on its heels, quantum dot cells. They've been close to commercialization for a while now but they seem to actually be arriving soon finally.
In your article he's implying that you can't make a profit at the current price of solar cells from China. I don't see much reason to believe that; non-Chinese manufacturers are able to meet the Chinese price. Of course if perovskite is cheaper to make then everyone will switch to that. Even if it's the same price, it'll have some advantages and thus be worth manufacturing.
His figure of 8 centimes per kWh for silicon panels seems quite high, so there's something missing. We're seeing projects bidding in at 3 US cents (which is about 3 centimes) per kWh, installed, with silicon panels in various parts of the world. The cells are less than half the cost. Maybe it's the figure for Lausanne given its cloudy weather?
