U.S. researchers have created an inorganic mixed halide perovskite solar cell which they claim shows no thermal degradation even at 200 degrees Celsius for three days. The device can be used in tandem junction cells and is designed for use in real-life environments with high solar irradiation.

While the solar and storage pairing is still relatively new, the growth over the next five years will be significant globally. As against just 5% in 2019, by 2025 more than 25% of all behind-the-meter solar systems will be paired with storage.

A study by the International Energy Agency into the chilling effect of the Covid-19 pandemic on energy demand states renewables will be ‘the only energy source likely to experience demand growth for the rest of 2020’. The slower the economic recovery, the more the fossil fuel industry will suffer.

Electroluminescence imaging is gaining traction in the field at project sites for operations and maintenance and to support PV plant mergers and acquisitions. EL testing can help PV asset owners evaluate power plant system health and can predict potential future underperformance and failures. Tristan Erion-Lorico, the head of PVEL’s module business, and dowstream business chief Andrew Sundling discuss the outlook for this enabling technology.

Analysts at Bloomberg New Energy Finance say the lowest-cost projects financed in Australia, China, Chile and the UAE in the last six months hit a levelized cost of energy of just $23-29/MWh and the best solar and wind projects will produce electricity for less than $20/MWh by 2030.

Analysis from Wood Mackenzie shows global inverter demand grew 18% last year. The ten largest inverter suppliers accounted for 76% of the global trade.

Russian researchers have improved the efficiency of a thin-fim GaAs‐based solar cell by 0.9% by applying single‐walled carbon nanotubes as the topmost layer. The cell also showed a slight increase in the short circuit current density, from 16.9 to 17.9 mA/cm2.

French organic PV module manufacturer Armor said it began manufacturing free-form PV modules in early April. The new technology will allow the company’s ASCA PV film to be produced in a range of different shapes.

How much granularity in monitoring and optimization is enough? Module-level power electronics have been a popular addition to the residential segment and, for several reasons, have enjoyed growing popularity on commercial rooftops. But where is the limit? While there are the first ground-mount installations with MLPE, other companies suggest that less is more and scaled down their optimization and monitoring granularity.

Researchers from Finland’s Lappeenranta University of Technology have assessed the economic advantages of a fully interconnected global network. They found that an international grid could contribute to a global LCOE of €52.50/MWh. The higher complexity of such a system, however, would only be marginally compensated by additional economic benefits.
