Researchers at the National Institute of Technology (NIT) Silchar, Assam, have designed a formamidinium tin iodide (FASnI3) active layer-based perovskite solar cell that achieves an admirable power conversion efficiency of 31.57% while scoring well on other performance parameters too. 

Chinese researchers have developed a solar cell using CsSnI3 perovskite, known for its unique phase transitions and near-IR emissions. By simulating the device with various electron transport layers (ETLs) and hole transport layers (HTLs), they determined that the optimal cell could be created using a titanium oxide (TiO2) ETL and a nickel(II) oxide (NiOx) HTL.

Scientists have used the US National Renewable Energy Laboratory’s (NREL) HOMER software to calculate the degradation of solar panels deployed in two rooftop PV systems operating in Germany since 2003. Their calculations focused on the energy productivity of the systems.

Research outfit Rethink Energy says the green hydrogen market could reach $850 billion in value by 2050.

NLC India Ltd is looking to engage a qualified coordinating agency (QCA) for its 1.4 GW of solar and wind power plants at various places in Tamil Nadu. The QCA will maintain the transmission of plant-level data and other required data to the state load dispatch center (SLDC), besides providing other services.

Powered by installation robots, on-site assembly line and digital twin software, the Terabase automated power plant construction system aims to boost productivity and cut construction costs.

The Indian multinational EPC company is setting up a pressurized alkaline electrolyzer factory with a capacity of 1 GW per annum. It expects to produce the first few electrolyzers from this facility by March next year. 

Nick Lanir Brown, chief business officer at Airtouch Solar, told pv magazine they would supply and install Airtouch AT 4.0 robotic panel cleaning systems for Adani Green Energy’s solar farm in Rajasthan.

Kaneka’s two-terminal tandem perovskite solar cell has achieved the highest efficiency ever recorded for such a device based on an industrial Czochralski (CZ) silicon wafer. It has an open-circuit voltage of 1.929 V, a short-circuit current density of 19.5 mA cm−2, and a fill factor of 77.55%.

First Solar has agreed to pay $38 million to buy Swedish manufacturing startup Evolar AB, as it seeks to expand development of high-efficiency tandem PV tech.
