With a design similar to that of lego bricks, the solar panels of Imperial College London capture 20% more energy
He is about to end up run over, his mother saves himAll 'Imperial College London they have found a way, simple simple and absolutely inexpensive, to make photovoltaic panels more efficient. You know the Lego bricks?
The current need of the photovoltaic industry is to increase the efficiency of the panels, i.e. the amount of sunlight transformed into electricity, without increasing module costs. Impossible? No, apparently: research works wonders and sometimes even simple solutions manage to lend a great hand.
This is the case of the study conducted by Imperial College London, from which it emerges that sprinkling the surface of solar panels with tiny small pieces of aluminum manages to increase the efficiency of these devices up to 20%. A great result, with an absolutely not noble material like aluminum.
The result is similar to what you see in this image, but in reality the bits of aluminum are much smaller than what was drawn.
Seen closely, these photovoltaic panels seem to be made with Lego bricks. And it is precisely this particular design that increases efficiency: when aluminum is hit by the sun's rays, it transmits light to the flat surface of the panel allowing it to absorb more of it. And therefore to produce more renewable electricity.
