Technology and R&D

Scientists at the Technische Universität Dresden, in Germany, have found that photon recycling and light scattering effects greatly improve light emission in perovskite solar cells, thereby boosting the upper limit for their efficiency to 31.3%.

The 100kW pilot vertical PV plant is being developed by French energy giant Engie. It will be used to test the effects of agrivoltaics on the microclimate, soil and vegetation.

Nitricity has developed an experimental plasma reactor that uses PV electricity to produce competitively priced, environmentally clean, nitrogen fertilizer. Its onsite fertilizer production eliminates emissions from transport, and provides a viable alternative to fossil-based nitrogen fixation methods like the Haber-Bosch process.

SMA’s new hybrid inverter reaches a maximum efficiency of 98.2% and a maximum European efficiency of 97.5%. It is compatible with DC-coupled high-voltage lithium-ion batteries from leading suppliers, according to the manufacturer.

The Sun Rock building is owned by Taiwan’s power utility Taipower. It was covered with 4,000 square meters of PV panels deployed by Dutch architectural firm MVRDV.

Sydney-based 5B has launched a AUD 33.4 million ($24 million) tech innovation program, including a AUD 14 million grant from the Australian Renewable Energy Agency, to accelerate the delivery of low-cost solar. Most of the investment is portioned off for an advanced manufacturing pilot line, but about one-third of the available funds will be used to deliver GPS-guided solar deployment robots.

The Indian manufacturer has unveiled its Series 10 monocrystalline PERC solar modules featuring 144 half-cells based on an M10 wafer. The modules are available in monofacial and bifacial versions with a maximum efficiency of 21.33% and 21.13%, respectively.

Fortescue Future Industries (FFI) and Covestro also want to partner on the supply of green hydrogen and its derivatives, including green ammonia. And the Indian government is cooperating with the IRENA to scale-up hydrogen and renewable energy projects.

Compiled by an international research group, the best practices were collected from all available guidelines published by national agencies, regulatory bodies, and trade associations.

The Korea Institute of Energy Research has developed a 3kW solar noise barrier to produce electricity and heat. The thermal solar modules reduce the operating temperature of the photovoltaic panels by absorbing excess heat.
