The supply of indium, both for layers in silicon solar cells and some thin-film PV technologies, is increasingly seen as a future potential bottleneck that solar and other industries relying on the material will have to manage. Resolving indium supply concerns may be a case of rethinking mining waste and recycling, reports Ian Morse.

Sunman Energy claims the new factory, located in Yangzhong City in China’s Jiangsu province, is the world’s largest production facility for lightweight photovoltaics.

Wood Mackenzie has predicted solar equipment cost increases will ease back after last year saw the average cost of solar electricity rise for the first time in the Asia-Pacific region.

The completed acquisition of ClipperCreek launches Enphase Energy into the fast-growing market for electric vehicle charging systems.

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.

A U.S.-Israeli consortium is developing synchroinverters – inverters that mimic a synchronous generator and are able to actively respond to the grid’s frequency changes while stabilising the voltage. The new devices are expected to do this simultaneously and provide grid stability services in less than 16.67 milliseconds.

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.
