Zinc oxide is applied to a substrate at a low temperature by using a mixture of an organozinc compound and water carried in an inert gas. The resulting zinc oxide film has a relatively low resistivity which can be varied by addition of a group III element.

Chemical vapor deposition of zinc oxide films and products

Cells of a thin film solar module having opposed upper and lower electrodes are connected in series by a plurality of discrete conductive regions extending between each upper electrode and the lower electrode of an adjoining cell. In a preferred embodiment, the opposite electrodes of adjoining cells overlap one another and one of the electrodes is a transparent conductive pad with a thickened metal-containing portion to aid in interconnection. In another embodiment, the conductive regions are formed by applying laser pulses to spaced locations along the areas of electrode overlap, after which a conductor may be deposited into cavities formed by the laser pulses.
