Technology and R&D

Researchers from the City University of Hong Kong have developed an all-inorganic perovskite cell with an electron-pair donor which offers a pair of non-bonding electrons. The cell was developed by applying that ‘Lewis base’ small molecule to passivate the inorganic perovskite film.

The Chinese manufacturer has achieved conversion efficiencies of 21.82% and 22.49% for its p-type PERC and n-type HOT bifacial panels, respectively. The results were confirmed by Germany’s TÜV Rheinland.

Fire safety engineering researchers have demonstrated increasing the gap between the modules of commercial PV arrays and flat roof surfaces is a decisive factor in reducing fire risks. Experiments have identified a critical gap height below which flame spread rate increases significantly.

As it moves towards grid connection this month, the solar project in the south of Oman demonstrates the value proposition of n-type PV cell technology, Chinese solar manufacturer Jolywood has argued at the World Future Energy Summit. The project is said to be the largest n-type bifacial array in the world.

The winners of the 2019 pv magazine awards have been recognized in a ceremony alongside the World Future Energy Summit. The victors spoke of the importance of innovation being recognized within the industry.

The Australian peer-to-peer energy-trading pioneer has purchased a 250 kW solar system that will use its new energy data management and settlement system to provide greater visibility on renewable energy sold to consumers under power purchase agreements.

Researchers from Saudi Arabia’s King Abdullah University of Science and Technology have created flexible solar cells made of crystalline silicon. They claim to have stretched a crystalline silicon cell’s surface by around 95% while maintaining conversion efficiency of around 19%.

The government of the state of Western Australia has allocated funding from its Renewable Hydrogen Fund toward seven feasibility studies that could pave the way for significant renewable hydrogen projects around the state.

An international research group led by CIC EnergiGUNE, a Spanish research center, is designing new redox organic flow batteries. The researchers claim the batteries will offer longer duration, as well as higher power and energy densities, in a more environmentally sustainable format. The European Commission provided €3.8 million in funding for the initiative.

Is First Solar stalled in innovation and growth? Markus Beck, a thin-film solar expert and former chief technologist at First Solar, provides an industry perspective on the fate of thin-film PV in the United States.
