Achieved by scientists led by the National University of Singapore, the result is the highest efficiency ever recorded for a perovskite-CIS tandem solar cell at the research level to date. The researchers used methyldiammonium diiodide (MDADI) to reduce open-circuit voltage losses in the top perovskite cell.

A Spanish-Algerian reserch group has tested how “cool roofs” could help increase power yield in rootop bifacial PV systems. Cool roofs are based on coating materials with high reflectance properties.

Tongwei has developed the G12 TOPcon solar module series, with efficiency ratings up to 23.1% and a temperature coefficient of -0.30% per degree Celsius.

The IQ8-3P solar microinverter enables peak power output of up to 480 W.

In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.

Researchers in China have built a prototype of a spectral-splitting concentrator agrivoltaic system (SCAPV) with a PV efficiency of 9.9, a hybrid light-use efficiency rating of 9.05%, and a levelized cost of energy (LCOE) of $0.033/kWh.

In its first commercial project, Terabase Energy successfully installed 17 MW of a 225 MW solar facility with its automated Terafab platform.

First Solar and its cadmium telluride (CdTe) technology dominate thin-film solar in the mainstream market. Valerie Thompson looks at the US-based business and the future of thin-film PV technology.

Egyptian researchers have developed a multi-string PV system with a converter control strategy, achieving 99.81% efficiency with a direct duty cycle for maximum power point tracking (MPPT).

FNB Gas has unveiled plans for a hydrogen core network in Germany, while Tree Energy Solutions has started working on an electrolyzer and 1 GW of renewable energy assets in Canada.
