There is a sense in the PV cell and module market at the mid stage of 2019 that the push towards high-efficiency cell architectures is accelerating. This makes the case for half-cut cells in a module more compelling, and the quality of the cut edge vital – argue laser process suppliers.

Following the Indian government’s 40 GW plan for the states, Telangana has pitched for setting up a 5 GW lithium ion plant by announcing the ready availability of 200 acres of land and power and water for the fab at a concessional rate.

Pitched as a solution between dual-axis and single-axis trackers, the 2-axis solar tracker offers a yield increase comparable with dual-axis trackers at a significantly lower cost.

A team of researchers from Manchester University claims to have identified the dominant process causing light-induced degradation in silicon solar cells. The process, termed “trap-assisted auger recombination”, arises from a defect in the bulk of the silicon material which lies dormant until exposed to sunlight.

The preliminary proposals must reach the ministry by June 30. These will be examined by a committee and the shortlisted parties will be invited to submit final proposal.

Chinese solar modules currently meet around 80% of India’s demand. Domestic modules face stiff competition from those imported from China, which cost 10-20% less, even after the imposition of safeguard duties.

Electric vehicles could account for more than half of all passenger cars and buses sold throughout the world within the next two decades, according to a new report by BloombergNEF. Sliding lithium-ion battery costs will make EVs cheaper than vehicles based on internal combustion engines by the mid- to late-2020s, the research firm says.

U.S.-based PV Evolution Labs (PVEL) has found that Vikram Solar’s Somera monocrystalline silicon and Eldora polycrystalline silicon PV modules met and exceeded international quality and performance benchmarks.

A research team has applied a waterproof coating obtained from graphite to a perovskite cell intended to power the production of hydrogen underwater. The cell is said to have worked underwater longer than expected.

Waste-to-energy, battery lifecycle solutions and hazardous waste management will make up an increased share of Fortum’s business in future. While solar will continue to be a mainstay for the Finnish clean energy company in India, Fortum wants to deepen its presence in the electric vehicle space with smart solutions, according to Sanjay Aggarwal, the company’s India MD, and Juha Suomi, area director for Asia, who spoke exclusively to pv magazine.
