Ultra-Thin, Flexible Solar Cells Could Soon Coat and Power Your Stuff | Developed at Oxford, the cells are just 1 micron thick, but they match conventional materials in efficiency.
Developed at Oxford, the cells are just 1 micron thick, but they match conventional materials in efficiency.
“During just five years experimenting with our stacking or multi-junction approach we have raised power conversion efficiency from around 6% to over 27%, close to the limits of what single-layer photovoltaics can achieve today,” said Shuaifeng Hu, a post-doctoral fellow at Oxford who worked on the project. Scientists have been hard at work in recent years to make solar power a more feasible option, going so far as to develop cells that can create electricity from water, as well as light. “We can envisage perovskite coatings being applied to broader types of surface to generate cheap solar power, such as the roof of cars and buildings and even the backs of mobile phones,” said Junke Wang, a postdoctoral fellow at Oxford.
