The authorities in the Philippines say the nation is on target to add 1.98 GW of solar this year, alongside 590 MW of battery storage, as part of more than 4 GW of renewable energy projects.

German research institute Fraunhofer ISE has unveiled a new metallization process for heterojunction solar cells that reportedly increases power conversion efficiencies by over 0.1% while reducing silver consumption. A device built with the new technique achieved an efficiency of 23.2%.

Conceived by scientists in China, the device consists of a Fresnel lens, a PV cell, and liquid ionic thermocells (iTECs) with electrolyte flow. In can reportedly outperform CPV systems built with thermoelectric generators, both in terms of costs and efficiency.

Australian battery company Li-S Energy claims to have taken a significant step toward proving the safety of its semi-solid-state lithium-sulfur batteries, with the third-generation technology successfully passing a series of nail penetration tests.

SJVN is now accepting bids to develop 1.2 GW of solar projects, connected to India’s interstate transmission system, anywhere in the country. Bidding closes on June 17.

Microsoft has signed on for 10.5 GW of renewable energy with Brookfield Renewable Partners. The projects might cost more than $11.5 billion to build, according to BloombergNEF.

The UK-based manufacturer said the new Ecomod 290HT products have a size ranging from 15 kW to 50 kW and a coefficent of performance of up to 4.9. The systems can reportedly achieve a flow temperature of 75 C.

Indian manufacturer Statcon Energiaa has introduced a single-phase grid-tie solar inverter intended for application in residential and small commercial buildings.

The 3.33 kW / 6.65 kWh lithium-ferro-phosphate battery offers home backup and storage of rooftop solar generation.
