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.

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.

Chinese manufacturer Jolywood claims it has reached 23.5% cell efficiency on the production lines for its n-type TOPCon technology. The achievement, which has not been verified by a third party, represents a 0.3% improvement to Jolywood’s reported mass production efficiency.

Chinese solar manufacturer Talesun has announced plans to raise up to $226 million to expand PV cell and module production capacity by up to 2 GW, with a focus on heterojunction and TOPCon technologies.

TOPCon cell technology has become one of the two leading next-generation options after mono PERC. But for the n-type architecture to truly become a rival to PERC, high-quality and cost-effective production technologies must become settled.

Three more PV manufacturers are jostling to announce plans to invest in an expansion of production capacities as the industry appears to make light of coronavirus fears.

As it moves towards grid connection this month, the solar project in the south of Oman demonstrates the value proposition of n-type PV cell technology, Chinese solar manufacturer Jolywood has argued at the World Future Energy Summit. The project is said to be the largest n-type bifacial array in the world.

Huanghe Hydropower Development has started work on the first phase of a huge renewable energy project which will eventually feature 10 GW of solar generation capacity along with 5 GW of wind and 1 GW of concentrating solar power. Trina will supply 600 MW of modules to the first phase of the facility.

There is movement in the heterojunction space, but will it be enough to surpass PERC’s momentum? New production lines show promise, but they might also be the last roll of the dice for Swiss production equipment supplier Meyer Burger.

This week pv magazine was in Amsterdam for the sixth edition of the BifiPV workshop, where the discussion focused on the impressive achievements made by bifacial solar modules and the challenges the technology faces as it moves toward mainstream adoption.
