Researchers led by the University of Rochester claim to have increased the photoresponsivity of a lead-halide perovskite for solar cell applications by 250%. They created a perovskite film with a plasmonic substrate made of hyperbolic metamaterial and characterized it with transition dipole orientation.

U.S. researchers have designed a molten salt battery that uses an aluminum cathode that charges quickly and reportedly enables longer-duration discharge.

An international research group claims that raw materials and land availability do not present a real barrier for a global energy system with solar at its center. They said that forecasts for PV growth should not have their axis on utility-scale power plants and instead consider vertical PV, agrivoltaics, and floating PV as the source of future big market volumes.

Researchers say that lightweight, high-performance perovskite solar modules could soon become competitive with crystalline PV modules in the residential segment, as such products will likely have lower manufacturing and balance-of-system costs in the future.

Antora Energy says its new 2 MW factory will make thermophotovoltaic cells for thermal storage applications. The cells are based on III-V semiconductors and reportedly have a heat-to-electricity conversion efficiency of more than 40%.

A U.S. research team has developed a cadmium telluride (CdTe) solar cell through a lift-off method that reportedly ensures higher crystallinity of the cadmium sulfide film. The device has a power conversion efficiency of 12.60%, an open-circuit voltage of 0.829 V, a short-circuit current density of 23.64 mA/cm2, and a fill factor of 64.30%.

Researchers have proposed the use of solar inverters in utility-scale solar assets to replace expensive voltage compensators, in order to provide voltage support at night. They said reactive power from PV inverters could be significantly cheaper and suggested the introduction of incentives to convince PV plant owners.

Growatt’s new 6 kW inverters have an efficiency rating of 93% and offer 12,000 VA of surge power, up to 500 V of input voltage, and 8 kW of PV input capacity.

Canadian researchers have developed a new model to improve the performance of building-integrated PV (BIPV) shades in buildings. They considered solar electricity, heat transferred through windows, and interior daylighting quality.

Longi said it has achieved a 26.81% efficiency rating for an unspecified heterojunction solar cell, as confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH).
