and we let the silicon absorb all the infrared. and in doing that we actually fundamentally improve the efficiencies. if we made a perfect perovskite on silicon tandem cell, that would top out at about 45%. so we ve fundamentally lifted the ceiling. and if we went one step further to anotherjunction, triple junction, three junctions, that would top out at just above 50%. so what perovskite does is lift the ceiling for potential efficiency and gives us a new path forward to go to higher and higher efficiency. so, i mean, substantial gains in efficiency here. how close is this really to being a real technology? is this now, or this is far flung future? this is very near term. you can t go out today and buy perovskite solar cells, but we re building a production line at the moment. we re talking about next year, the first cells and modules will be in production and start to be
is far flung future? this is very near term. you can t go out today and buy perovskite solar cells, but we re building a production line at the moment. we re talking about next year, the first cells and modules will be in production, and start to be deployed in the world. so this is all fantastic, this is state of the art technology and engineering that is market ready or nearly market ready. so is the message i should get that you are going to gallop to my rescue when it comes to climate change? that i can carry on with my life as i always have, and everything is going to be fine, because the engineers are going to sort it all out? henry, i want to start with you. is that what i should be taking away from this? that is not what you should be taking away, but you should feel encouraged that there can be solutions. but we all need to. it s a challenging road ahead. there s a lot of scale that needs to happen

cells on top of each other. and the perovskite we tune to match perfectly silicon. it absorbs only the visible light and we let the silicon absorb all the infrared. and in doing that we actually fundamentally improve the efficiencies. if we made a perfect perovskite on silicon tandem cell, that would top out at about 45%. so we ve fundamentally lifted the ceiling. and if we went one step further to anotherjunction, triple junction, three junctions, that would top out at just above 50%. so what perovskite does is lift the ceiling for potential efficiency and gives us a new path forward to go to higher and higher efficiency. so, i mean, substantial gains in efficiency here. how close is this really to being a real technology? is this now, or this is far flung future? this is very near term. you can t go out today and buy perovskite solar cells, but we re building a production line at the moment. we re talking about next year, the first cells and modules
