Classification: CPC H  Y | IPC H

Claim 0:
1. A printed solar film comprising:
a carrier substrate;
a plurality of printed photovoltaic modules produced on the carrier substrate via a roll-to-roll process, each module having a predetermined layout, each module including:
first and second module terminals, and
a predetermined number of printed photovoltaic cells between the first and second module terminals such that each photovoltaic cell is electrically connected in series with an adjacent photovoltaic cell;
a first printed bus bar extending along one side of the photovoltaic modules;
a second printed bus bar extending along an opposite side of the photovoltaic modules, each of the photovoltaic cells being positioned such that a longitudinal direction of each photovoltaic cell is parallel to the first and second bus bars; and
a plurality of inter-module rails, each inter-module rail is:
produced on the carrier substrate via the roll-to-roll process,
connected to at least one of the first and second module terminals of one or more of the -plurality of printed photovoltaic modules, and
printed with a linkable gap such that the photovoltaic modules are initially disconnected from one another;
a conductive paste, a conductive ink or a conductive tape dispensed over at least the respective linkable gap of one or more of the inter-module rails after the one or more of the inter-module rails are produced via the roll-to-roll process;
wherein the plurality of inter-module rails are at least partly located between adjacent photovoltaic modules in the longitudinal direction; and
wherein the plurality of inter-module rails and gaps or connections between the first and second module terminals and the first and second printed bus bars define a plurality of selectively configurable junctions at predetermined locations on the carrier substrate external to the plurality of photovoltaic modules.
