Researchers in Singapore have developed a perovskite solar cell via a new method to synthesize the capping without using lead. The cell is capped with a zinc-based compound and reportedly has a conversion efficiency of 24.1%.

Despite the ever-growing number of nations committing to attaining a net-zero economy, there appears little prospect yet of a future free of fossil fuels, as Roger Lewis, an environmental, social, and corporate governance (ESG) expert at Downing LLP explains.

The global agrivoltaics market is pegged at a 10.1% annual growth rate, according to a research note by Allied Analytics.

Solar industries bodies including SolarPower Europe, Germany’s BSW and Ukraine’s ASEU have joined forces to send a stream of modules, inverters and batteries to embattled Ukraine. The donations are critical as some hospitals have been without power for weeks, leaving surgeons to operate under headlamps.

With calls for a revival in European PV manufacturing becoming more urgent, the Environmental, Social, and Governance credentials of its PV producers are being touted as a way in which manufacturing can be supported or even protected. The case for the ESG credentials of European manufacturing was advanced by multiple speakers at the 2023 SolarPower Summit this week in Brussels.

MAN Energy Solutions is building an industrial-scale heat pump that generates steam without using gas. It will produce steam to dry dairy ingredients at a milk farm in New Zealand.

When it comes to gravity batteries, pumped-hydro storage is the gold standard, but its cost and topography-specific limitations are driving innovations ranging from freight-train braking to super-dense liquids. We consider whether any of the new technologies can punch above their weight.

Competition is intensifying in the electrolyzer space. With the International Energy Agency (IEA) expecting 380 GW of hydrogen production capacity in 2030, four different technologies will likely become prominent as demand spikes. We take a look at the market.

Australian grid operator Transgrid has partnered with German machinery manufacturer Zeck for the use of its innovative steel separation tech. Zeck’s machine can process electricity transmission lines into a recycle-ready state onsite. Previously, Transgrid sent old transmission lines offshore for this process at a much higher cost.

US researchers are studying how agrivoltaic systems mounted on single-axis trackers affect rainfall and light redistribution at a 1.2 MW installation on grassland in Boulder, Colorado.
