The PV industry has experienced several rounds of price increases since the second half of 2020, from polysilicon to materials such as PV glass and films. Between July 2020 and February 2021, prices quoted for 3.2 mm and 2 mm glass surged by more than 60% per square meter. Prices for EVA and POE encapsulant films skyrocketed by more than 40% and 10%, respectively. Prices for silver paste also rose 7%, and have since remained stubbornly high. PV InfoLink Chief Analyst Corrine Lin examines the impact of silver’s recent price turbulence on PV cell manufacturing.
