The world of solar energy continues to develop, and apart from lowering the prices of the panels, new ones appear with new technologies that provide them with better applications.
This is the case of the ultra-thin solar cell presented by MIT researchers. In addition to being extremely thin (it is much less thick than a human hair), it weighs 100 times less than conventional ones, and can generate 18 times more energy per kg of cell weight.
Apparently they are almost all advantages, because due to its thinness it can be placed on any surface, and make it quickly become a solar panel.
The manufacture is not complicated and is done by printing on a surface conductive inks that react to sunlight. This means that its manufacture can be scalable, and very fine solar cells can be obtained in a short time at competitive prices.

Its light weight is a huge advantage. To power a house, they are needed panels that provide about 8,000 Wh., and they weigh almost 1,000 kg, which are usually placed on the roof. With these new cells, that energy could be achieved with considerably less than 50 kg. The difference is abysmal.
Of course, the announcement made by the researchers is only the beginning. They have years of work left to perfect and strengthen the processes, and later take everything to manufacturing. But taking into account the interest it has aroused, it is possible that in a few years we will see real examples producing energy.
Hopefully it will be like that.
