Taiwan’s Ministry of Economic Affairs (MoEA) says it will offer up to TWD 300,000 ($9,260) per project through a $126 million rebate program for small rooftop PV systems, with eligibility limited to systems not exceeding 3 kW.

Conceived by a research team from Germany’s University of Potsdam and the Chinese Academy of Sciences, the tandem cell is based on a wide-bandgap perovskite bottom cell and a narrow-bandgap organic top device. The researchers used a compound known as cyclohexane 1,4-diammonium diiodide for suface passivation.

Scientists in the United Kingdom have simulated how a 1 GW off-grid agrivoltaic facility may be used to fuel hydrogen fuel electric cell vehicles across Australia, California, China, Nigeria, and Spain. Their techno-economic analysis showed that the proposed combination could provide a levelized cost of hydrogen ranging from $3.90/kg to $8.13/kg.

The two research institutes used silver nanowire grids as an alternative to indium tin oxide for the cell’s transparent electrodes. They claim this is the first time that a metallic nanostructure offers photonic gain in a solar cell.

New research from China shows that regions with dense PV installations, such as Southern China, Central and Northern Europe, Central and Eastern America, and Japan, are the most exposed to weather-related extreme low-production events. The researchers proposed a mitigation strategy to reduce the impact of these events on PV power generation.

An international research team has fabricated a perovskite solar cell using sulfur-based additives to improve its resistance to moisture. The device not only achieved high efficiency levels but was also able to retain about 96% of its efficiency after 1,000 h.

Interested developers will have time until February 3 to submit their proposals.

The Chinese manufacturer said its new products have a capacity of up to 5.1 kWh and are scalable up to 20.48 kWh. The systems feature a depth of discharge of 90% and can purportedly operate for more than 6,000 cycles.

Panasonic has unveiled a new version of its Eco Cute CO2 heat pump that produces domestic hot water mostly during daytime based on solar radiation data. It integrates a dedicated app to obtain day-ahead solar forecasts and schedule water heating hours for the next day.

The researchers of the German institute explained that UV-induced degradation may cause larger than expected efficiency and voltage losses in all dominant cell technologies, including TOPCon devices. The scientists expect that silicon nitride layers could be used to enhance TOPCon UV stability compared to PECVD layers typically utilized in PERC and heterojunction cells.
