Researchers in Taiwan have developed an organic PV module with an active area of 216 sq cm. The panel is said to have open circuit voltage of 10.6 V and short circuit current of 1.82 mA. It also features the highest efficiency reported for a panel of its kind which has an active area of more than 100cm2

Polysilicon maker GCL-Poly has started construction of a factory with an annual production capacity of 54,000 MT as Chinese inverter manufacturer Goodwe launched an IPO on the Shanghai stock market.

Researchers in Germany are scaling up efforts to bring perovskite-silicon tandem solar cell technology into industrial scale production. The scientists say manufacturing cells of that kind is possible on widely-available six-inch silicon wafers and modular systems are being designed to do so at scale.

Chinese researchers have discovered a new hydrothermal method for the direct deposition of antimony sulfide-selenide films. They used ethylenediaminetetraacetic acid to regulate the reaction system, giving the film a flat, compact surface morphology. It has an efficiency of 10.5%, an open-circuit voltage of 664 mV, a short-circuit current of 23.8 mA cm−2, and a fill factor of 66.3%.

Scientists led by the Technical University of Munich have packed a variety of perovskite and organic solar cells onto a rocket, and sent it into orbit 240 kilometers above the planet’s surface. Their results demonstrate strong potential for such technologies to power satellites and even deep space missions.

Longyuan has revealed plans to build a 350 MW hybrid wind-solar plant in Shandong province. China Resources, meanwhile, said it will build 200 MW of floating solar in Hubei province.

Netherlands based manufacturer Energyra this week introduced a new back contact module, which it has developed in partnership with Dutch research institute TNO and Germany’s ISC Konstanz. A prototype module was unveiled yesterday in a small presentation at Energyra’s factory in Zaandam, Netherlands. The company is targeting large-scale manufacturing by the end of 2020.

The South Korean PV manufacturers is bringing its three most powerful solar panels to Europe. All of them are based on its Q.antum Duo Z tech, which reduces the gaps between cells and drives up module efficiency by 4% in relative terms.

A Chinese research group has developed a PERC cell on a commercial 180-μm-thick monocrystalline silicon wafer with a standard size of 156 × 156 mm2. The cell has an open-circuit voltage (VOC) of 0.677 V, a short short-circuit current (ISC) of 9.63 A, and a fill factor of 80.30%.

The South Korean government has released a new roadmap to support R&D activities in the solar sector. The document indicates the country’s solar manufacturing industry may be encouraged to opt for high-efficiency and expensive panels based on tandem solar cells.
