NOVELTY - Connecting photovoltaic cells within a photovoltaic module comprises disposing a photosensitized interconnected nanoparticle material and a charge carrier material on a first conductive layer of a first base material; providing a wire; and joining a second base material having a second conductive layer to the first base material.    USE - For connecting photovoltaic cells within a photovoltaic module.    ADVANTAGE - Any debris that forms in the wake of the heated stylus is encapsulated in the base material when it cools so that any scoring-related debris cannot interfere with the performance of a photovoltaic cell or module formed using the process of the invention.    DETAILED DESCRIPTION - Connecting photovoltaic cells within a photovoltaic module comprises providing a first base material including a substrate (609) having a first conductive layer; disposing a photosensitized interconnected nanoparticle material (603) and a charge carrier material (606) on the first conductive layer; providing a wire; and joining a second base material including a substrate (612) having a second conductive layer to the first base material such that the first and second conductive layers are in electrical contact with the wire.    INDEPENDENT CLAIMS are also included for:    (a) a photovoltaic module comprising a photosensitized interconnected nanoparticle layer and a charge carrier material disposed on the first conductive layer; a wire; and a second base material including a substrate having a second conductive layer and joined to the first base material such that the first and second conductive layers are in electrical contact with the wire;    (b) a method of scoring by providing a first coated base material and scoring the coating of the first coated base material at a temperature elevated enough to part the coating and melt at least a portion of the first base material;    (c) a method of forming a photovoltaic cell by providing a metal foil; applying a nanoparticle material to the metal foil; heating the nanoparticle material to form an interconnected nanoparticle material; and disposing between first and second flexible substrates the metal foil coated with the interconnected nanoparticle material;    (d) a method of interconnecting nanoparticles at low temperatures on a rigid substrate by applying a solution comprising a polymeric linking agent and a solvent to the rigid substrate; and contacting metal oxide nanoparticles with the solution at below 300degreesC to interconnect at least a portion of the metal oxide nanoparticles.
