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.

Greece to overhaul licensing regime which puts the brakes on solar

The energy ministry has published a plan to radically simplify the renewable energy permitting process. The new system is expected to come into force as early as next month and will be applied retroactively to address a 22-month backlog in generation license applications.

‘Renewables must grow four times faster to ensure sustainable future’

The share of renewables in the global energy mix must more than double by 2030 for the world to advance the energy transition and achieve sustainable development goals, according to the International Renewable Energy Agency. Renewable electricity should supply 57% of global power by the end of the decade, up from 26% today.

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.

Jolywood says 105 MW Oman project demonstrates value of n-type

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.
