Gallery: MIT Develops ‘Inverted Nanopyramid’ Solar Surface That Cuts Si...


A team of researchers at MIT has developed a new type of textured solar surface that could bring down the cost of photovoltaic technology by reducing the thickness of silicon used by more than 90% while still maintaining high efficiency. To create the surface MIT modified a silicon sheet with a pattern of tiny inverted pyramids. These indentations, each less than a millionth of a meter across, are able to trap light rays just as effectively as solid silicon surfaces – which are 30 times thicker.
