Scientist holds and bends a small piece of transparent material

In a groundbreaking development, researchers at Oxford University have created a new solar power-generating material that can be applied to everyday objects such as rucksacks, cars, and mobile phones, potentially revolutionizing the way we harness solar energy. This innovative approach could allow for the generation of solar electricity without relying on conventional silicon-based solar panels.

The team at Oxford has introduced a thin, flexible material that absorbs light and can be coated onto nearly any surface. This material utilizes a multi-junction approach, stacking multiple light-absorbing layers within a single solar cell. This technique captures a broader spectrum of light, thereby increasing the energy produced from the sunlight received.

Notably, this thin-film perovskite material has achieved an impressive energy efficiency rate of over 27%, as certified by Japan’s National Institute of Advanced Industrial Science and Technology (AIST). This marks a significant milestone, matching the efficiency of traditional silicon photovoltaics for the first time. Dr. Shuaifeng Hu, a postdoctoral fellow at Oxford University Physics, highlighted the rapid progress of this technology, noting an increase in power conversion efficiency from about 6% to over 27% within just five years.

The material’s ultra-thin nature—being just over one micron thick, nearly 150 times thinner than a standard silicon wafer—adds to its versatility. It can be applied not only to conventional surfaces like the roofs of buildings but also to more innovative locations such as vehicle roofs and the backs of mobile phones. This adaptability could significantly expand the use of solar energy in daily applications and reduce the reliance on large-scale solar farms and traditional panel installations.

The research is spearheaded by Professor Henry Snaith, a leading figure in renewable energy at Oxford, and involves a team of 40 specialists. Their work over the past decade has primarily focused on enhancing the capabilities of perovskite photovoltaics.

Furthermore, Oxford PV, a company originating from the university’s physics department and founded by Professor Snaith in 2010, has begun large-scale production of these innovative photovoltaics in Brandenburg-an-der-Havel, Germany. This facility is recognized as the world’s first major manufacturing line for “perovskite-on-silicon” tandem solar cells, signifying a significant step forward in the commercial application of this technology.
