All-inorganic perovskite solar cell hits 16.1% efficiency

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.

Jinko claims two more efficiency records for bifacial panels

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.

Mind the gap

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.

Western Australia to fund renewable hydrogen feasibility studies

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.

New organic redox flow battery aims for €0.05/kWh/cycle by 2030

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.
