Technology and R&D

The Dutch consortium has achieved the record result by combining, in a four-terminal tandem configuration, an 18.6% efficient highly near-infrared transparent perovskite with a prototype of a c-Si interdigitated back contact (IBC) silicon heteroJunction (SHJ) cell developed by Japanese electronics manufacturer Panasonic. The perovskite cell was also combined with other kinds of solar cells and other remarkable record efficiencies were hit.

Italian start-up Genius Watter has developed a solar desalination solution that is claimed to be particularly suitable for remote areas with no connection to grid electricity. The system is able to produce up to 1,000 cubic meters of potable water per day at an opex of €0.20 per cubic meter.

Oxfordshire-based Oxis Energy says it will produce the less flammable devices sought by the aviation industry using the same manufacturing processes as those used to make lithium-ion and conventional-lithium-sulfur products.

A new study from Australia has highlighted the potential of polysilicon passivated junctions for revolutionizing the commercial production of crystalline silicon solar panels. It also presented, however, the technical and economic hurdles that must still be removed to ensure its success, including the damage that this technology can produce for the polysilicon layers, due to the cell’s metallization process.

The database brings together photovoltaic performance data and meteorological values from PV systems located in all climate zones. It is being built by an international consortium including the Fraunhofer Center for Silicon Photovoltaics CSP, and the Anhalt University of Applied Sciences.

Storegga, Shell and Harbour Energy want to set up a 20 MW blue hydrogen production facility in the U.K. Australia’s Origin Energy wants to build a hydrogen facility at the Port of Townsville, in Queensland. South African company Sasol and Toyota South Africa Motors have announced a partnership to “commence exploration of the development of a green hydrogen mobility ecosystem in South Africa,” starting with zero-emission hydrogen fuel cell (FC) heavy-duty, long-haul trucks.

An group of international scientists has developed a mathematical model to design hybrid renewable energy systems relying on pumped hydro storage for islands. According to their analysis, which was applied to the Ometepe island in Nicaragua, a similar system could provide a cost of energy ranging from €0.047/kWh to €0.095/kWh.

A technology-focused event held by the Africa Solar Industry Association has heard development pipelines across the continent are swiftly changing to accommodate double-sided PV panels, and that’s good news for solar tracker providers too.

Researchers in the US ascertained that the partial shading provided by solar parks creates a microclimate that favors the abundant growth of more varied flowers and pollinators. They also found that partial shading increases bloom abundance by delaying bloom timing, increasing forage for pollinators during the hot and dry late season.

EnerVenue signed its first major distribution agreement with Hong Kong’s Towngas. The deal will pilot the company’s nickel-hydrogen battery technology and serve as an audition for future deals to come.
