Abstract
Transparent conductors for use in a variety of different photovoltaic devices are disclosed, comprising at least one ZnO transparent conductor layer having a predetermined level of haziness achieved, e.g., through appropriate variation in the parameters employed in formation of the transparent conductor (for example, by chemical vapor deposition) and/or through treatment of the transparent conductor subsequent to its formation. The concentration and/or relative rate of introduction of dopant during the deposition of the transparent conductor may be adjusted to prepare films having the desired morphology and/or structure. Alternatively, the morphology, composition and/or structure of the transparent conductor may be modified by suitable post-formation treatments. A combination of at least two transparent layers may also be employed, comprising at least a first layer designed primarily to maximize the optical properties and at least a second layer designed to maximize the electrical properties.
