Solar cell contact structures formed from metal paste

Abstract

Solar cell contact structures formed from metal paste and methods of forming solar cell contact structures from metal paste are described. In a first example, a solar cell includes a substrate. A semiconductor region is disposed in or above the substrate. A contact structure is disposed on the semiconductor region and includes a conductive layer in contact with the semiconductor region. The conductive layer includes a matrix binder having aluminum/silicon (Al/Si) particles and an inert filler material dispersed therein. In a second example, a solar cell includes a substrate. A semiconductor region is disposed in or above the substrate. A contact structure is disposed on the semiconductor region and includes a conductive layer in contact with the semiconductor region. The conductive layer includes an agent for increasing a hydrophobic characteristic of the conductive layer.
