UK researchers have developed a stable alkaline-based hybrid polysulfide-air redox flow battery that reduces “crossover” issues via a new dual-membrane-structured flow cell.

A new perovskite PV cell based on titanium dioxide nanoparticles exhibits low efficiency losses when scaled up from cell to module.

The Irish authorities have kicked off a new procurement exercise, together with the commissioning of the first solar park built under the nation’s first renewables auction. French developer Neoen built the 8 MW facility at a location south of Dublin.

The Seoul Metropolitan Government has revealed that it will subsidize building-integrated photovoltaic projects through a new rebate scheme.

Tesvolt’s new E Series includes the TS-I HV 80 battery and the TS-I HV 100 battery, with storage capacities of 80 kWh and 90 kWh, respectively. Both of the devices have efficiencies of up to 98%.

German startup Nexol has developed a photovoltaic water heating system that relies on a smart controller, with either DC and AC power. It decides autonomously if grid electricity or PV is used, with the latter always preferred.

OCI will supply polysilicon from its manufacturing facility in Malaysia, which is expected to have an annual capacity of 35,000 metric tons by the end of June.

Japan’s Kopel has developed a device with a thickness of just 1.2 mm, with contacts on all of the finger electrodes of busbar-less solar cells.

The Iranian authorities have kicked off a tender to select development proposals for solar projects up to 10 MW in size, from both domestic and foreign investors.

France’s environmental agency Ademe has released a set of new guidelines that clearly define “agrivoltaics.”
