singlet fission

New discovery promises to bring singlet fission enhanced C-Si solar cells nearer to commercial production

New research from Australia has shown that singlet fission solar cells do not only have the potential to raise the theoretical efficiency of the PV technology to unexpected levels but also to provide a better temperature behavior and longer duration compared to conventional PV devices. The scientists believe that this technique may help conventional crystalline silicon solar cell technologies reach efficiencies close to 30%.

Designer molecules enable ‘two for one’ efficiency boost

Scientists in the U.S. have come a step closer to taking advantage of singlet fission – a phenomenon seen in certain solar cell materials that promises to greatly increase energy yield. By designing and testing various molecules, the group was able to better understand the fundamental processes behind the mechanism and optimize materials to better take advantage of it.

German scientists work on efficiency boosting cell concept

Researchers from Berlin’s Helmholtz Zentrum Research Institute have developed a silicon heterojunction cell, with an additional crystalline layer that utilizes an effect known as singlet fission to boost efficiency. The team has created a device demonstrating that the principle works, and says that with further experimentation, the concept could achieve cell efficiencies as high as 40%.
