Scientists in South Korea combined two processes to etch a nanostructure of tiny pyramids onto the surface of a silicon wafer. As well as trapping more light and increasing the cell efficiency, the group claims that its nanostructure improves the mechanical flexibility of the cells. This could potentially allow for the use of much thinner silicon wafers than is currently possible in production.
Researchers in South Korea have used the process to increase performance and the replicability of large-area organic cells. The method was used during film formation to speed up solvent evaporation.
