Momentum builds for perovskite tandems, 25%+ efficiency achieved

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.

Accolades flow as UNSW’s Green awarded Global Energy Prize

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.

Tandem PV cells present potential for residential applications, MIT scientists say

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.

EU grants €5 million to perovskite research consortium

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.

Fraunhofer ISE, Schmid develop production line concept for custom design modules

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%.

Solliance achieves 14.5% cell efficiency on perovskite module

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.

University of Wollongong researchers unveil new sodium-ion battery design

Scientists from the University of Wollongong have developed prototype battery cells based on sodium-ion technology, which the university says can achieve excellent cycling stability and easily be scaled up to mass production.

SERIS researchers develop new multi-cSi texturing technique

Scientists from the Solar Energy Research Institute of Singapore (SERIS) have announced the development of a new wet chemical process to allow multi-cSi wafers to be cut with diamond wire saw technology, and subsequently textured to reduce their reflectivity.

RMIT researchers demonstrate first working proton battery

Scientists at Royal Melbourne Institute of Technology (RMIT) have demonstrated the first working example of a ‘proton battery’, which utilizes a carbon electrode and reversible hydrogen fuel cell for the storage of energy. The scientists say that their small prototype has already demonstrated similar storage capacities to commercially available lithium-ion batteries, with plenty of potential for further optimization.
