Conductive paste, method for manufacturing solar battery, and solar battery

摘要

A conductive paste used for a rear electrode of a Si solar battery includes an Al powder, a glass frit, an organic vehicle and particles insoluble or slightly soluble in the organic vehicle. The particles are constituted of an organic compound or carbon or both. The conductive paste does not shrink much during firing and, consequently reduces the amount of Si wafer warping while maintaining the functions of a rear electrode for a Si solar battery.
