US engineers have built a scalable thermal energy storage prototype system that combines the best latent and sensible heat transfers. The technology, which is now market-ready after three years of testing, consists of engineered cementitious materials and thermosiphons in a combination that enables fast, efficient thermal performance at low cost.

A US-Canadian group of scientists has used Lewis base molecules to improve surface passivation in a perovskite solar cell. The team produced a device with a high open-circuit voltage and remarkable stability levels.

A numerical study by researchers at India’s Chitkara University shows enhanced performance in the top device of a tandem solar cell based on copper indium gallium selenide (CIGS). The design had a higher open-circuit voltage, with the top cell acting as a current-limiting cell.

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.

Researchers in Germany have assessed direct coupling and integration between PV and batteries at the scale of a single PV module. They say their solution could be cheaper and provide superior performance than maximum power point tracking (MPPT) in optimizing PV system performance.

Chinese scientists have simulated a new photovoltaic-thermoelectric technology, based on radiative cooling and III-V solar cells, to generate electricity at night.

Rajasthan Electronics & Instruments Ltd is accepting bids from domestic manufacturers to supply 1,540 quantities of 660±4 Wp mono PERC modules. Bidding is open until February 21.

Indian scientists have developed a panel with an electrical efficiency of 13% and and thermal efficiency of 66.6 %. They built the system with a 100 W PV panel, a rectangular absorber, and a cooling technique based on a phase change material (PCM) that uses biochar derived from water hyacinth.

The HVDC and power quality product factory will cater to the rising number of high-voltage transmission projects in India and export to support global HVDC installations.

India’s Emmvee Group has appointed Germany’s Fraunhofer Institute for Solar Energy as the technology partner for its upcoming 1.5 GW PV cell manufacturing facility.
