Researchers in Spain claim to have recorded the highest power conversion efficiency result for a four-terminal tandem organic cell to date. The device is based on an ultrathin transparent silver electrode.

The Chinese manufacturer said its new frameless module can be installed on a balcony through nylon cable ties, without the need for any mounting structure. The new product features a power output of 200 W and a power conversion efficiency of 16.2%.

Researchers in India have simulated a 4 kW solar power-based hybrid electric vehicle (EV) charging station using a three-stage charging strategy and found that the station is capable of charging 10–12 EVs with 48 V 30 Ah lithium-ion batteries.

A Saudi research group has assessed how polymeric coatings, such as polyethylene terephthalate (PET) and polydimethylsiloxane (PDMS), could be used for radiative cooling in photovoltaic panels and has found that both materials could reduce the operating PV module temperature by between 1.15 C and 1.35 C.

Vale and Central South University have launched a joint laboratory for low-carbon and hydrogen metallurgy in Changsha, in China’s Hunan province, while Nippon Steel has secured approval to acquire U.S. Steel.

Europe’s solar boom is hiding its waste through exports, according to a new study. Instead of recycling, as expected under European regulations, vast amounts of solar panel waste are exported, undermining sustainability goals. The researchers suggest a digitized value chain as a potential fix to work toward a circular economy.

Dismissed by many in the solar industry as an overly-complex, outdated technology, concentrated solar power (CSP) is set for a comeback thanks to a scaled-down, modular approach.

Sud Renovables has installed a pilot vertical rooftop PV system on one of its facilities in Barcelona, Spain. The array features two 500 W bifacial modules from US-based SunPower and two microinverters from Enphase Energy.

France’s indoor organic PV specialist Dracula Technologies and Swiss-headquartered semiconductor manufacturer STMicroelectronics demonstrated a battery-free illuminometer at the Embedded World trade fair in Germany last week.

Researchers in Taiwan have discovered that in polysilicon production the crucible angular speed affects the oxygen concentration near the crucible wall, which in turn affects the wafers’ mechanical and electrical properties. They simulated a Czochralski process for an ingot with a diameter of 200 mm diameter and a length of 700 mm.
