TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Current-Collector: The trace further comprises an electrically conductive core. The trace further comprises nickel. The trace further comprises an electrically conductive core and a layer overlying the electrically conductive core, the layer overlying the electrically conductive core comprising nickel. The current-limiting portion comprises a layer of current-limiting material disposed coating at least a portion of the trace. The current-limiting portion of a segment of the power-loss-inhibiting current-collector has a resistance that increases with occurrence of a shunt defect in the solar cell located in proximity to a contact between the current-limiting portion of the segment of the power-loss-inhibiting current-collector and the solar cell. The current-limiting portion is integrated with the trace. The current-limiting portion further comprises a positive-temperature-coefficient-of-electrical-resistance structure having a positive temperature coefficient of electrical resistance, the positive-temperature-coefficient-of-electrical-resistance structure comprising a low-conductivity matrix portion; and high-conductivity portions dispersed in the low-conductivity matrix portion. The low-conductivity matrix portion of the positive-temperature-coefficient-of-electrical-resistance structure is selected from a thermoplastic, an epoxy, an adhesive, an electrical varnish and a binder of an ink. The high-conductivity portions dispersed in the low-conductivity matrix of the positive-temperature-coefficient-of-electrical-resistance structure is selected from silver, tin, nickel, and carbon. The current-limiting portion further comprises a material selected from current-limiting materials consisting of silver oxide, nickel oxide, indium tin oxide, zinc oxide, aluminum zinc oxide, resistive aluminum zinc oxide, a conductive carbon-containing material and a conductive nitrogen-containing material. A combined solar-cell, power-loss-inhibiting current-collector comprises a solar cell; and a power-loss-inhibiting current-collector comprising a trace for collecting current from the solar cell; and a current-limiting portion coupled with the trace, the current-limiting portion configured to regulate current flow through the power-loss-inhibiting current collector. Preferred System: The current-regulating means of a segment of the system for photovoltaic current-collection has a resistance that increases with occurrence of a shunt defect in the photovoltaic-convertor means located in proximity to a contact between the current-regulating means of the segment of the system for photovoltaic current-collection and the photovoltaic-convertor means.
