A new measurment and solar simulator instrument designed for perovskite-silicon tandem cells and encapsulated mini-modules is the latest product from a collaboration between Canadian solar simulator supplier G2V Optics and U.S.-based measurement instrumentation company Sinton Instruments.

Verde Technologies, a U.S.-based spinoff of the University of Vermont specializing in single junction and all thin-film tandem perovskite solar technologies, has demonstrated that its coating processes are transferable to existing commercial roll-to-roll manufacturing lines in a project with compatriot manufacturer Verico Technology.

Pixel Voltaic, a spinoff of University of Porto, has launched a laser system to hermetically seal glass-glass and glass-steel perovskite PV modules up to 30 cm x 30 cm. The company’s technology roadmap is to increase capacity to accommodate larger device areas of up to 1 m2, and to modify the process to operate within a roll-to-roll line.

The Euro trade body has promised to monitor the developing solar jobs market annually from now on, and pointed to Poland’s position at the top of the tree of EU member states for PV jobs last year as evidence the technology can still benefit from legislative backing.

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.

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.

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.
