Researchers led by Belgian institute imec claim to have achieved the result with a 1cm² flexible thin-film cell intended for building-integrated PV application. The result tops the 24.6% efficiency the consortium announced in September 2018. The cell’s developers are now aiming for 30%.

Australian researchers have compiled data from 173 studies which examined homeowner behavior when buying rooftop PV and identified 333 predictors related to the attitude, knowledge, tendency, awareness, willingness and intent of householders.

The Australian research team which developed the device said the higher efficiency was achieved through a nanowire design which eliminates the interface inside the titanium dioxide band.

Australian researchers have unveiled hydrogenation technology to reduce light and elevated temperature-induced degradation in Czochralski silicon PERC solar cells. The developers say the process can minimize degradation without sacrificing performance in cells and modules.

The Minerals Council South Africa has urged the government to solve the country’s energy crisis by adding more power generation capacity from both distributed and large-scale renewables. Meanwhile, several mining companies operating in South Africa are planning their own big solar parks, including two 200 MW facilities under development by Sibanye-Stillwater and Vedanta.

UK researchers claim to have proved the viability wearable photovoltaic devices as an integral part of regular clothing. A solar-powered fabric textile was created by embedding micro crystalline silicon solar cells within the fibers of a textile through very thin copper wires. The scientists claim that the novel device can maintain its performance even after 15 domestic machine wash cycles, 25 hand wash cycles, and 6000 abrasion cycles.

A study from Finland’s Lappeenranta University of Technology has predicted solar and other renewables can provide a global energy jobs revolution – just as four European operations revealed recent struggles.

The Chinese manufacturer said the result was confirmed by Germany’s TÜV Rheinland. The achievement beats the company’s previous record of 21.65%, set last month.

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.
