A bus grid structure is affixed to a photovoltaic device utilizing a double-sided adhesive tape in which one of the adhesive layers is electrically conductive and the other is electrically resistive. The tape is affixed to a photovoltaic device via the electrically resistive adhesive. Grid wires are applied to a top electrode of the photovoltaic device, and portions of those grid wires are adhered to the electrically conductive adhesive. A bus bar is also adhered to the electrically conductive adhesive so as to contact the portions of the grid wire. The assembly is laminated so as to bond the grid wires to the photovoltaic device and to the bus bar. Further disclosed are devices fabricated according to this method as well as electrically conductive double adhesive tapes utilized in the process.

Large area, thin-film body of photovoltaic material is subdivided into a plurality of small area devices. Through a selective etching process, a portion of the bottom electrode of each small area device is exposed. A metallic contact member is deposited upon the exposed portion of the electrode and a series connection between adjoining cells is established by interconnecting the metallic contact member of a first cell with the top electrode of an adjoining cell, so as to provide a large-area photovoltaic device including a plurality of interconnected sub-cells.

An improved photovoltaic device in which an electrically conductive adhesive is employed to affix the grid structure to the upper electrode thereof. By appropriately selecting the resistivity of the conductive adhesive, normal photogenerated current flow is readily accommodated, while shunted current flow, through patent or latent defects is substantially eliminated.

An electronic device of the type including a thin film body having a superposed electrode has short circuit defects therein passivated by a conversion process in which the electrical resistivity of the electrode material is increased proximate the defect regions. Conversion is accomplished by exposing the electrode material to a conversion reagent and activating the reagent proximate the defect regions. The process may be utilized for a variety of differently configured devices, and may be readily adapted for use in a roll-to-roll device fabrication process.

A light directing element for a photovoltaic device and method of manufacture. The light directing element is in the form of an encapsulating cover which fits onto the top of the underlying photovoltaic cell. A bottom surface of the encapsulating cover is provided with V-shaped grooves which are in registry with the underlying grid lines of the photovoltaic cell. Preferably, the side walls of the grooves are coated with a reflective coating. Incident light, falling on the reflective side walls will be reflected onto adjacent portions of the photovoltaic cell, thereby minimizing shading effects caused by the grid lines. In a particularly preferred embodiment, each groove in the cover is filled with a conductive carbon paste, and conductive wires are embedded therein. This conductive wires serve as the current collecting network of the solar cell and are in electrical communication with the top electrode thereof by means of the conductive carbon paste. This embodiment has the desirable combination of decreased shading, and lower electrical resistance of the current collecting network.
