Photovoltaics at multi-terawatt scale: Waiting is not an option

Sophia Haussener, Stefaan De Wolf

A major renewable-energy milestone occurred in 2022: Photovoltaics (PV) exceeded a global installed capacity of 1 TWdc. But despite considerable growth and cost reduction over time, PV is still a small part of global electricity generation (4 to 5% for 202 ...
