ITRPV: Large formats are here to stay

The 2021 edition of the International Technology Roadmap for Photovoltaics (ITRPV) was published today by German engineering association VDMA. The report, which forecasts technology trends across the solar industry, expects PERC to maintain its position as the dominant cell technology and notes that large wafer formats are here to stay.

Simulating PV’s silver future

Scientists at Germany’s Fraunhofer ISE developed a model to simulate different setups for screen printing in solar cell metallization. The model provides a comparable ‘screen utility index’ value that can predict the usefulness of different architectures in the printing equipment in relation to the properties of a given silver paste. The approach, says Fraunhofer, will assist the PV industry in reducing the amounts of silver needed in silicon cell manufacturing.

RENA picks up 15 GW equipment order

Germany based PV equipment supplier RENA Technologies has received what it describes as its ‘biggest ever order’, from a tier 1 manufacturer in Asia, for 15 GW of its wafer texturing equipment. Financial details of the deal have not been disclosed, although the company states that the order is worth “tens of millions of euros.”

Slimming down on silver

Using an innovative high-speed video setup, scientists in Germany were able to observe the screen-printing process used in solar cell metallization, on a time scale of less than 50 milliseconds. Insights into the paste’s behavior and the mechanisms at work during screen printing will improve the process and the formulation of the silver paste it relies on.

Meyer Burger seals $100 million HJT order, expects to hit break-even in first half

Swiss equipment supplier Meyer Burger has signed a contract to supply heterojunction cell manufacturing equipment to an unnamed North American manufacturer. The company also posted its preliminary results for the first half, posting a $14 million EBITDA loss but stating it expects to break even for the period after selling its wafer business.

Seraphim plans 1.5 GW solar module, 300 MW cell fab in Africa

Chinese solar PV manufacturer, Seraphim has inaugurated a US$14 million, 300 MW solar PV module manufacturing facility in South Africa. Plans are in place to ramp this up to 1.5 GW over the next three years, and add 300 MW of cell production.

Neo Solar Power increases turnover, reduces losses

On the last stretch to the merger between NSP, Gintech and Solartech, the company still posted losses due to “operational challenges” and solar trade disputes.

REC Group places equipment order with Aurora Solar Tech

Aurora Solar Technologies today announced that it has received an order from Norway headquartered vertically integrated PV manufacturer REC Group for its inline cell measurement equipment. The order is expected to ship in January 2018.

Jakson Group to add 1.25 GW of solar manufacturing capacity in India

The Indian energy solution provider Jakson is making an INR 7 billion ($0.11 billion) investment to build 1 GW of solar module manufacturing capacity and a 250 MW solar cell manufacturing plant in Gujarat.

Video: industrial LID ‘fix’ for multi PERC drawing closer

PERC application in monocrystalline cells has proven its capability to produce high efficiency cells. Further cost reductions could be achieved with multi PERC, but problems with Light Induced Degradation (LID) has stood in the way of its industry adoption. However, researchers and equipment suppliers are drawing in on an industrial solution.
