As far as our limited capacities are concerned, the sun is essentially an infinite and renewable energy source. It’s like a giant fusion reactor millions of miles away, illuminating the earth with as much energy as the whole of human civilization uses in a year! So, why aren’t we making more use of such a boundless source to solve all our energy-related problems?
Well, we’re actually pretty close to getting there, and in today’s video, I will show you how!

Solar photovoltaic panels are currently limited to a maximum efficiency of about 30%, and in practice only actually achieve about 20% to 23% efficiency. Now a team in Cambridge has developed a film that can amplify the number of photons that the panel can use, with a potential increase in efficiency to as much as 35%. So how do they do that?
