New dopants may improve PV glass performance

According to a British-Swedish research team, the down‐shifting process for solar glass manufacturing can be improved through the use of two dopant cations that produce no absorption bands. The doping with these compounds is said to reduce the UV transmission while also keeping the glass free from absorption in the visible and near-infrared ranges.

Pouch lamination technique for solar cell encapsulation

Scientists in India have used a pouch laminator to encapsulate a polycrystalline solar cell. The resulting device, the researchers claim, showed better UV photon absorption than solar cells treated with a polymer surface coating.

Identifying early-stage discoloration in EVA encapsulants

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