Developed by Korean scientists through a novel lift-off-based patterning approach based on swelling-induced crack propagation, the perovskite PV device achieved an open-circuit voltage of 1.16 V, a short-circuit current density of 22.5 mA/cm2, and a fill factor of 77%. With the microcells, the researchers also built a first prototype of a solar window which they claim has vivid colors and high color purity.

Chinese inverter maker Growatt has launched Infinity 1500, a portable power station for off-grid applications.

Myanmar’s government has announced a plan to increase conventional and renewable energy generation to address electricity shortages. Reports from Burmese exiles, however, detail increasing issues for the construction of large scale solar projects tendered prior to the military coup in February 2021 and Chinese inverter manufacturer Sungrow said the project it secured in the country’s first tender has been canceled.

Daqo announced its best quarterly financial results, with net profit reaching $535.8 million, while Sungrow saw its profit drop by 19%. Polysilicon manufacturer GCL-Poly changed its name to GCL Technology Holdings Limited and announced a plan to build another 100,000 MT polysilicon factory in Inner Mongolia in partnership with Zhonghuan Semiconductor.

In an upcoming pv magazine Webinar, Chinese manufacturer JA Solar will present its M10 DeepBlue 3.0 modules based on gallium-doped technology for either rooftop or large-scale applications. The company’s senior technical manager, Ignacio Espinosa, discusses the advantages offered by the M10 technology.

A new report from the Netherlands Organisation for Applied Scientific Research (TNO) shows the strong potential of photovoltaics in all scenarios for the country’s future energy mix. According to the Dutch experts, solar may reach between 55 GW and 132 GW by 2050.

The cell is based on ferrocene and is claimed to retain more than 98% of its initial efficiency after continuously operating at the maximum power point for 1,500 hours under standard illumination conditions.

US scientists have utilized a nanochannels device to cool down the operating temperature of a commercial PV module and have found that the proposed technique is able to improve power yield by up to 32.8%. Spray droplets are dispersed over the nanochannels device in order to eliminate the need for a continuous supply of a coolant.

A third of the 17 MW solar array is now completed. The installation is expected to cover around 17% of the theme park’s electricity needs. Final completion is scheduled for 2023.

Two different studies have highlighted the potential and challenges of low-head pumped hydro storage (PHS), which has so far never been implemented in real projects. Different main areas were identified for future research and an interesting levelized cost of storage was indicated for certain project configurations.
