    Abstract: A doped photovoltaic device is presented. The photovoltaic device includes a semiconductor absorber layer or stack disposed between a front contact and a back contact. The absorber layer comprises cadmium, selenium, and tellurium doped with Ag, and optionally with Cu. The Ag dopant may be added to the absorber in amounts ranging from 5×1015/cm3 to 2.5×1017/cm3 via any of several methods of application before, during, or after deposition of the absorber layer. The photovoltaic device has improved Fill Factor and PMAX at higher Pr(=Isc*Voc product) values, e.g. about 160 W, which results in improved conversion efficiency compared to a device not doped with Ag. Improved PT may result from increased Isc, increased Voc, or both.

    Abstract: Described herein is a photovoltaic module and method of manufacturing a photovoltaic module to isolate potentially stress-damaged portions of cells from non-stress-damaged portions thereof. The module has a plurality of columnar photovoltaic cells, and at least one isolation scribe at a first edge of an active area of the photovoltaic module and extending across a photovoltaic cell in a direction perpendicular to a length of the columnar cells, where the at least one isolation scribe is deep enough to electrically isolate portions of the photovoltaic cell on opposite sides of the at least one isolation scribe.
