Germany’s TÜV Rheinland said it will invest €22 million in the 5,000 m2 facility for testing photovoltaic modules as part of a massive lab.
Antora Energy says its new 2 MW factory will make thermophotovoltaic cells for thermal storage applications. The cells are based on III-V semiconductors and reportedly have a heat-to-electricity conversion efficiency of more than 40%.
Italian researchers have analyzed different ways to assess the levelized cost of energy (LCoE) of perovskite solar cells and modules. They said a common approach should soon be defined to increase the market maturity of the tech.
The potential of perovskite solar cells and modules is still held back by issues such as stability and efficiency losses when scaling up from cell to module. But Annalisa Bruno, a scientist at Singapore’s Nanyang Technological University, says most of these challenges could be overcome in the near future, with this technology extending from building-integrated PV to conventional solar projects.
Two of Australia’s richest people are expected to be rivals in the bidding process for Sun Cable, the developer of what could be the world’s biggest intercontinental solar and energy storage project. Administrators indicate that the sale process could be completed within three months.
