Useless solar cell machine may start improving batteries
Using a device, the ECN research center wanted to produce solar cells. The device could vaporize silicon onto solar cells, but unfortunately not with a density of the silicon that was high enough. As a result, the device lay gathering dust, until Christian Rood came across it and saw how useful the device could be for producing batteries.
