Entering the cleanroom where the Photovoltaic Materials and Devices (PVMD) group does their research is a tedious process. Overalls, hoods, mouth covers, latex gloves and boots must all be donned before entering the sensitive area of manufacturing and scientific research. Amongst several cubicles stands an imposing machine, Amigo, a plasma enhanced chemical vapour depositor. PhD candidates Pavel Babal and Martijn van Sebille use it to fabricate solar cells. The cleanroom, found in the Dimes building, is the only lab in the Netherlands with the ability to make silicon-based solar cells from start to finish. “The future of solar cells is in more diverse products, such as wearable, flexible and portable solar cells,” says van Sebille. “And solar energy could provide a substantial amount of energy for the world. In the future, up to one third,” adds Babal.
