Modules & Upstream Manufacturing

Deployment in the building integrated PV segment is accelerating, and so too are the number of solar products available to architects and developers. And while BIPV had long been the segment in which an array of thin-film technologies could shine, they are now in increasingly stiff competition with crystalline silicon rivals.

World beating Sydney-based startup SunDrive has given itself an early Christmas present in the form of the fabrication of its first full-sized panel. This panel marks the most recent milestone on the road to commercialisation for SunDrive, which set a new world record for commercial-sized silicon solar cell efficiency in September.

Developed by German researchers, the 20.9%-efficient device was built with an architecture avoiding the use of the ionic dopants or metal oxide nanoparticles that are commonly used to contact the cell, as these can be subject to secondary reactions at higher temperatures.

The Chinese bifacial module maker has commissioned a 1.5 GW TOPCon cell factory in China’s Zhejiang province, which raised its total TOPCon cell capacity to 3.6 GW. Another 16 GW facility is being planned for the Shanxi province.

Scientists in the United States developed a computer simulator that can calculate the conversion efficiency of different solar cell materials and configurations – helping to guide research and optimisation of new cell designs. The simulator is available to researchers as an open-source tool to save time and spot the best opportunities for optimisation of any given approach.

The hype surrounding green hydrogen is real, but does the cost-reduction outlook for its production technologies live up to it? Christian Roselund looks at the technology, transportation, application and enabling policies behind the promising green energy carrier.

China is once again the focus of attention across the global solar PV industry. The country’s manufacturers have had a turbulent 2021, but domestic demand remains strong, particularly from the booming residential rooftop segment. Despite the supply challenges, China will likely reach 50 GW this year and possibly even 100 GW next year. Given the dynamic market and policy landscape, pv magazine publisher Eckhart K. Gouras recently caught up with long-time China solar expert Frank Haugwitz, the founder of the Asia Europe Clean Energy (Solar) Advisory (AECEA).

The polysilicon producer is sticking by plans to ramp up manufacturing capacity almost 300% within three years and says it will produce the basic material for the new generation of n-type solar panels.

Australia’s solar PV panel manufacturing capacity is set to get a major boost with Melbourne-based RTE Energy confirming it plans to establish a large-scale heterojunction module factory in the Lansdown Eco-Industrial Precinct being developed in northern Queensland.

Gujarat-based solar manufacturer Solex plans to have 1 GW of cell and 3.7 GW of module capacity operational in 2023.
