German scientists have developed a perovskite PV cell with remarkable stability by adding a bilayer of polymers that protects the perovskite from corrosion. This design helps to shield the extremely sensitive perovskite interface and provides the cell with extraordinarily high conductivity.

South Korean energy producer South-East Power has started operating a 150 MW solar plant in South Jeolla province. The project was partly backed by crowdfunding among local residents.

SUN Energy’s 100 MW Merredin Solar Farm in Western Australia has emerged as the country’s best performing utility-scale PV project in 2021. International consultancy Rystad Energy says it has delivered an average capacity factor of 29.6% for the calendar year.

A massive solar noise barrier in the US state of Massachusetts is expected to generate 802,000kWh of electricity per year, or the equivalent of annually supplying 120 homes with power.

A preliminary ruling by the European Court of Justice states panel makers should not be responsible for electrical waste management costs in a seven-year period as the rules in place before the EU’s WEEE directive entered force, in 2012, permitted member states to place the obligation on panel users instead. The resulting change in law, in some states, cannot be applied retroactively, under EU legal rules.

In the next ten years, according to Milanese consultant REF-E’s simulations, storage in Italy will mostly be driven by opportunities in the ancillary services market. After 2030, when renewables will provide most electricity, REF-E believes the price spread between different hours of the day should be high enough to cover the cost-per-cycle of energy-intensive storage. Energy expert Virginia Canazza discussed the topic with pv magazine.

Scientists in Australia have analyzed the state-of-the-art of all gettering technologies used in the solar industry. This technique, which is aimed at reducing defects in wafer manufacturing, may become more important in the future, as cell efficiencies increase and become increasingly sensitive to traces of metallic impurities.

Egyptian researchers have analyzed all cooling techniques for solar module cooling. Their review includes passive and active cooling methods, cooling with phase change materials (PCMs), and cooling with PCM and other additives, such as nanoparticles or porous metal.

The 120MW facility is selling power to State Grid Corporation of China at a price of RMB0.453/kWh ($0.0762). It relies on 21.2%-efficient JT SSh(B) 450W/455W high-efficiency dual-glass panels provided by Chinese manufacturer Jetion.

With solar water pumps, farmers have access to high-quality power available for irrigation. These systems are portable and can be assembled at any preferred location. With the growing utilization of these systems, the costs have decreased substantially, making them an efficient, convenient and cost-effective solution for grid-isolated rural areas.
