Researchers at Swansea University in Wales, led by Dr. Dave Worsley in the Materials Research Centre at the University's School of Engineering, are investigating ways of painting solar cells onto the flexible steel surfaces commonly used for cladding buildings. Unlike conventional solar cells, the materials being developed at Swansea are more efficient at capturing low light radiation. The researchers’ aim is to produce cells that can be painted onto a flexible steel surface at a rate of 30-40 sq m/min.
