perovskite solar modules

Chinese solar perovskite specialist Mellow Energy and the Jinan University developed a new manufacturing process for perovskite solar modules that enables the formation of a protective layer at the interface between the perovskite absorber and the electron transport layer. This prevents the effusion of volatile components from the perovksite film.

China Three Gorges has commissioned a 1 MW pilot solar plant with perovskite panels near Ordos, in China’s Inner Mongolia region. This marks the world’s first commercial PV system to use perovskite tech and features 11,200 modules from an undisclosed manufacturer.

The China National Institute of Metrology has certified the result. The manufacturer claims it was able to increase the panel efficiency from 16.02% to 18.04% in a few months.

GCL-SI has launched a new 320 W perovskite solar module. The company guarantees that the 10-year end power output will be at least 90% of the nominal output power, which decreases to 80% after 25 years.

Futurasun, an Italian module manufacturer, has acquired Rome-based Solertix. It now aims to bring its perovskite-based solar cell technology closer to commercial production.

Scientists in Belgium have developed perovskite solar panels with a thermally stable device stack. The encapsulated bifacial panels they created with this configuration were able to retain around 92% of their initial efficiency after 1,000 hours.

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.

Scientists in Singapore have reviewed all thermal evaporation techniques for the production of perovskite solar cells and modules. Despite limitations, the new methods could lead to high production throughputs and more efficient products.

Chinese researchers have used inverted perovskite cells with a p-i-n structure to build a perovskite solar module with a reduced heat-affected zone. The panel achieved a power conversion efficiency of 21.07% and a geometric fill factor of 95.5%.
