Less is more: The road to low-carbon solar

Polysilicon prices finally began to fall again at the end of 2022, following a period in which solar manufacturers made efforts to reduce silicon consumption in wafer production. With polysilicon accounting for around half of the carbon footprint of a typical solar panel – albeit with wide variation – further silicon reductions could offer a compelling route to low-carbon production, reports InfoLink Consulting chief analyst Corrine Lin.
