Arizona State University researchers have determined that a 32% efficient perovskite-silicon tandem cell could produce electricity at the same price as cutting-edge 22% efficient panels in the most cost-competitive of situations

When pioneering and award-winning solar researcher Stuart Wenham passed away suddenly shortly before Christmas last year, some in the PV industry may have wondered what would become of his research into the role of hydrogen in crystalline silicon cells. His daughter, Alison Ciesla is answering that question alongside Wenham’s former team at UNSW, advancing its work into the crucial role of hydrogen in the degradation of silicon cells.

Belgian research institute Imec has announced the achievement of 27.1% efficiency on a perovskite/silicon tandem cell, providing further evidence of the technology’s potential to provide a low cost efficiency boost to existing PV technology.

Researchers from Helmholtz-Zentrum Berlin (HZB) and Oxford PV have presented a new record perovskite tandem solar cell, with a 25.2% conversion efficiency, independently verified by Fraunhofer ISE. Bernd Stannowski, from HZB presented the results this week at the World Conference on Photovoltaic Energy Conversion (WCPEC-7) in Hawaii.

Pioneering UNSW solar researcher Martin Green has received wide recognition for his achievement as being selected as one of the winners of 2018 Global Energy Prize. The prize means Green will split $820,000 in prize money with the co-winner, to go towards his research and teaching, and resulted in a congratulatory call from Prime Minister Malcolm Turnbull.

Martin Green and his UNSW collaborators have driven a wide range of innovations within the Chinese and global PV manufacturing sector. Green, a Scientia Professor at UNSW and the Director of the Australian Centre for Advanced Photovoltaics shares his take on PV technology in 2018.

Four different thin film solar PV technologies were tested by the MIT experts across three types of environment in the U.S.: Arid (Arizona); temperate (South Dakota); and humid (Florida). The research found that despite high costs, tandem cells may become viable in rooftop applications.

Belgian institute Imec will be the coordinator of a project involving many of Europe’s leading research organizations, which will focus on developing stable, scalable, low cost PV modules based on perovskite technology. The project, named ‘ESPResSo’ has received more than €5 million in funding from the European Union.

German research institute Fraunhofer Institute for Solar Energy Systems (ISE) and equipment supplier Schmid have jointly developed a production for customizable modules for building-integrated projects. According to Fraunhofer ISE, the concepts developed by joint study could reduce the production cost for BIPV modules as much as 35%.

Scientists at European solar research organization, Solliance have announced the achievement of 14.5% conversion efficiency on a perovskite module. The module uses a glass substrate, and the efficiency was measured on an aperture area of 144 cm².
