Cheaper Solar Cells Are Possible With Thinner Silicon Wafers
With improved handling methods, the researchers propose the thickness of wafers of silicon used to make silicon photovoltaic cells could be shaved from 160 micrometers down to 100 micrometers — and eventually as little as 40 micrometers or less, which would only require one-fourth as much silicon for a given size of panel.

An eco-friendly method for reclaimed silicon wafers from a photovoltaic module: from separation to cell …
A sustainable method for reclaiming silicon (Si) wafers from an end-of-life photovoltaic module is examined in this paper. A thermal process was employed to remove ethylene vinyl acetate and the back-sheet. We found that a ramp-up rate of 15 C min −1 and an annealing temperature of 480 C enabled recovery of the undamaged wafer from the module.
