Technology and R&D

A newly developed autonomous robotic cleaning solution for modules uses artificial intelligence to clean daily or on demand, without substantial human input.

French energy giant Engie recently commissioned a solar module testing facility in Chile’s Atacama Desert, a region which has the world’s highest solar radiation. Thore Müller – head of bifacial PV R&D and solar services at Engie Laborelec, talked to pv magazineabout the advantages of testing panels, inverters and cleaning systems in hot, arid environments.

The module – which measures 2,411×1,134×35mm, weighs 31.1kg and features 156 p-type monocrystalline cells – is available in five versions with power outputs of 565-585 W and efficiencies of 20.67-21.40%. Jinko says the Pro Tiger series will become the company’s main revenue stream in 2022, surpassing the Tiger 475 W panel.

Amid a growing appetite for sustainability from customers, Lithuanian solar panel maker Solitek is applying circular principles to its production operations. Measures include embracing digitalization and new approaches to design. Project manager Tadas Radavičius has spoken to pv magazine about the company’s work and how Solitek is supporting European projects which are considering circular solar.

Australian researchers have revealed a new cell that builds on an earlier 24.4%-efficient device. The upgrade was achieved with an oxide-nitride-oxide passivation stack which optimized diffusion and contact-area fraction, plus improved texturing with a monoTEX surfactant.

The long-awaited procurement exercise includes 250 MW of generation capacity originally intended to be tendered last year.

A technique proposed by scientists in the United Stated could raise solar plant output 5% and decrease panel degradation by more than 0.3% per year, according to the researchers. The approach is based on wind direction and speed, and module inclination.

The Swedish PV equipment supplier has launched Midsummer Magnum, a solar module for large rooftops. The manufacturer says the panel offers 14.54% efficiency and an output of 128.3 W per square meter. The company also unveiled a manufacturing process it claims can increase module output 10%.

Scientists led by the University of Cambridge have developed a new method to print a protective layer of copper directly onto a perovskite solar cell, providing protection to the active layer from damage often caused in later production stages. Cells using this layer were tested in various tandem combinations with silicon cells and achieved a maximum efficiency of 24.4%.

SunCrafter is a small German startup with a global ambition: to alleviate energy poverty by upcycling used solar PV modules. Having established an innovative business model, which sees it subsidizing its goals by meeting the infrastructure needs of big events and festivals, it has now partnered with EU-funded project Circusol to demonstrate the viability of circular renewables. pv magazine interviewed SunCrafter CEO and co-founder Lisa Wendzich as part of the UP initiative’s circular manufacturing quarterly theme.
