Jolywood signs mega-deal to supply 7 GW of household solar

Based on the price agreed for the first year of the five-year contract, the total deal would be worth almost $4 billion to the $1 billion company. However, with input costs rising and the state-owned sponsor likely to expect to pay lower fees for subsequent years, the TOPCon manufacturer’s margins may not remain so fat.

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.

Jolywood plans new Indonesian fab

The n-type TOPCon solar module manufacturer is preparing to invest in a joint venture with state-controlled local partner PT Len Agra Energy to set up 1 GW of annual cell and panel capacity.

Evaluating tandem cells, from the bottom up

Scientists in Germany evaluated multiple silicon cell concepts based on both cost and efficiency in serving as the bottom layer in a perovskite-silicon tandem cell. The study, based on both simulation and experimental work, outlines advantages to various approaches with the silicon cell and concludes that in almost every case, perovskite-silicon tandem cells have the potential to bring solar costs down below what could be achieved with silicon alone.

SNEC 2020 CEO Series – Interview with Liu Zhifeng, Vice GM of Jolywood

Jolywood is one of the few PV manufacturers, who has placed its bet on TOPCon technology. Instead of focusing on the simplicity of the production process, Jolywood believes the conversion rate is more critical. With years of efforts, the company has established its leading position among TOPCon players. During the SNEC 2020 in Shanghai, pv magazine had the opportunity to interview Liu Zhifeng, Vice General Manager of Jolywood, and listened to his views on some hot topics, especially the cell tech route.

New metallization paste range from Heraeus

The SOL 7 series comprises five products for Perc, Topcon and heterojunction devices.

Minimum mono Perc standards could halt Chinese production boom

The authorities in Beijing, concerned at ever greater solar production capacity announcements and oversupply fears, are preparing to introduce standards which would bring the recent mono Perc production explosion to a shuddering halt.

Solar parks may have better biodiversity impact than intensive monoculture farming

A research project in the Netherlands is seeking to assess the impact of large scale PV projects on soil quality and biodiversity. Principal scientist Wim Sinke, of Dutch research center TNO, says well-designed and operated and maintained solar parks could prove to have better outcomes than monoculture farming.
