Abstract

Crystalline photovoltaic (PV) cells and methods of manufacturing cells are described. One example method of manufacturing a PV cell includes depositing a plurality of first fingers on a crystalline silicon wafer. The first fingers extend in a first direction parallel to each other and comprise a substantially non-silver conductive material.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 737,589, filed December 14, 2012, the entire disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to photovoltaic (PV) cells and methods of making PV cells, and, more particularly, to crystalline PV cells having electrodes and methods of making the same. Background technique [0004] Photovoltaic (PV) modules are devices that convert solar energy into electricity. A PV module typically includes several PV cells (connected in series and / or in parallel) that generate electricity in response to sunlight incident on the surfaces of the cells. [0005] To extract energy from a PV cell, electrodes are fabricated on one or both surfaces of a crystalline silicon wafer. Various techniques for making PV cell electrodes are known. In one known method, electrodes including f...
