Modules & Upstream Manufacturing

South Korean scientists have developed a way to determine when a floating PV system is safe to install in the field.

Bisol’s new products feature a temperature coefficient of -0.34% per degree Celsius and a power rating of 400 W to 420 W. The Slovenian PV module manufacturer said it used M10 wafers for the first time.

A US research team has developed a cadmium telluride (CdTe) solar cell through a lift-off method that reportedly ensures higher crystallinity of the cadmium sulfide film. The device has a power conversion efficiency of 12.60%, an open-circuit voltage of 0.829 V, a short-circuit current density of 23.64 mA/cm2, and a fill factor of 64.30%.

The advanced manufacturing production (AMPC) credit and domestic content requirement (DCR) will be key to supporting the rapid development of the US renewable energy economy, says Wood Mackenzie.

The future outlook for copper indium gallium selenide (CIGS) solar cells is bright, due to recent R&D achievements and efficiency gains, according to Ayodhya Tiwari, head of laboratory at Switzerland’s Federal Laboratories for Materials Science and Technology (EMPA). CIGS has already shown its value in building-integrated PV applications, but as production volumes increase in the years ahead, ground-mount plants and big utility-scale installations could also become feasible, says Tiwari.

The US National Renewable Energy Laboratory (NREL) has achieved remarkable efficiency and stability for a wide-bandgap all-perovskite tandem solar cell. The scientist developed the device with an inverted architecture and used gas quenching instead of an antisolvent in the manufacturing process.

Longi Solar said it will invest CNY 42.5 billion ($6.65 billion) in 100 GW of wafer capacity and 50 GW of solar cell capacity in Shaanxi province, China.

Alessandro Romeo, associate professor in experimental physics at Università degli studi di Verona, speaks to pv magazine about the advantages of cadmium-telluride (CdTe) solar cells over other thin-film PV technologies, as well as the commercial implications of future efficiency gains and the prospects for industrial expansion.

French research institute CEA-INES has produced a 566 W heterojunction (HJT) demonstrator PV panel using Norwegian silicon wafers based on German polysilicon and solar cells made in France. The prototype has a carbon footprint of 317 kgCO2eq/kW, which is considerably lower than the maximum 800 kgCO2eq/kW standard for Chinese products.

Turkish module maker Kalyon Solar Technologies said it will use newly secured state funds to expand the capacity of its vertically integrated factory in Izmir by 1 GW.
