Researchers from China are proposing to use spent battery lead for creating a perovskite that can be used in the production of solar cells that are based on this promising material. The proposed one-step process, which was tested in the production of a 17.38% efficient perovskite heterojunction cell, is said to be cheaper and less energy-intensive than other recycling processes for waste lead from lead-acid batteries.

Establishment of an R&D cell for battery recycling and online tracking of the collection and re-processing of used batteries are highlights of the draft rules which seek to ensure safe disposal and organized recycling of batteries at the end of their life.

Global bids are invited for supply, installation and commissioning of two sets of 1500V 3-phase grid-connected outdoor PCUs for a 2x50MW solar plant at Raghanesda. Bidding closes on March 7.

Energy Efficiency Services Limited, which has already bagged orders for 800 MW of distributed solar installations in Maharashtra and 113 MW in Rajasthan, says it will roll out 1.5 GW of generation facilities by the end of the next fiscal year.

Although cells lose much of their power yield when submerged, they may not be useless. Researchers in India say submerged cells could be used in monitoring sensors and for other commercial and defense applications. An amorphous silicon cell from Panasonic was tested in their study.

March 2 is the last date to bid for supply of 5, 15, 20, 25, 30 and 50 KVA string inverters with inbuilt data loggers. Bids will open on March 3. Contract period is up to September 30.

Researchers from the Vellore Institute of Technology have tested a new inverter topology with a single-phase, induction-motor water pump. The seven-level inverter, with five power semiconductor switches, is said to be particularly efficient at reducing switching losses thanks to a pulse width modulation technique.

A new polymer developed by Indian researchers can mend its own cracks when exposed to ultraviolet light. The unique ability makes it an ideal candidate as a smart coating for photovoltaic solar devices to prevent damages and increase performances.

Having touched 1404 MW of renewable capacity as on January 31, 2020, the state-owned producer aims to add further 2847 MW to reach 4251 MW (4 GW from solar and 251 MW wind) by 2025.
