Innovation promises cheaper solar cell glass manufacturing

Indian scientists have developed a hybrid production method combining metal mesh and a metal-oxide layer over a glass substrate which they say brings down production cost by 80% compared to the tin-doped, indium oxide-based technology currently in use.

IIT Bombay group suggests method of detecting early-stage discoloration in EVA encapsulants

A new, non-destructive technique has been proposed by researchers who say identifying early-stage discoloration in EVA encapsulants can help detect degradation in solar panels before power output is affected. The IIT Bombay group used an ultraviolet accelerated aging test during 34 days on three encapsulant samples.

CEL tenders 3 MWp of multicrystalline solar modules

Bids are invited for supply of multi-crystalline solar modules, with peak power output of minimum 325 Wp each, to different substations in various districts of Maharashtra and Uttar Pradesh. Bidding closes on March 5.

How do solar cells work underwater?

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.

Bharat Heavy Electricals opens tender to procure 12m polycrystalline solar cells

The state-owned engineer has specified the dimensions of the devices required and the bid window will close on Friday.
