Abstract: In accordance with one or more embodiments herein, a method of manufacturing a photovoltaic (PV) top module, to be used together with a PV bottom module, e.g an SI-based PV bottom module, is provided. The method may include monolithically interconnecting a plurality of thin film based PV sub-cells, manufactured using a perovskite material and/or a CIGS material as solar absorbing material, in series on a substrate in order to create a PV top module including at least one first PV top sub-module, and arranging metal grid lines on top and bottom contact layers of the PV top module. The metal grid lines may be arranged either above or below the top and bottom contact layers of the PV top module.

Abstract: A work bench includes a work surface with a spline assembly supported adjacent work surface. The spline assembly includes a longitudinally extended spline body and a longitudinally extended raceway cover. The spline body has an upper portion and two side arms extending downwardly from the upper portion. The spline body defines a channel for carrying a power track between the two side arms. The raceway cover is configured to attach to the two side arms of the spline body below the power track, and defines a raceway for carrying cables underneath the spline body.

Abstract: The invention relates to a method for producing a thin film solar cell module and thin film solar cell module thus produces. The method comprises the steps of forming a multi-layer structure (100) of multiple electrically interconnected thin film solar cells (1) on a substrate (2), the multi-layer structure comprising a back contact layer (10), a photovoltaic active layer (11), and a front contact layer (13); and forming a conductive grid (3) underneath or onto the front contact layer by depositing a conductive material through a mask (4) before or after forming the front contact layer (13), by moving the substrate (2) and the mask (4) with respect to a deposition source (5) of the conductive material.

Abstract: A photovoltaic module and a method for producing such modules is presented in which the resistance of the interconnects between neighboring photovoltaic cells is minimized and the dead-area is also minimized. This is achieved by routing the interconnects, in form of a finger, from a top contact of a first photovoltaic cell to a bottom contact of a second photovoltaic cell. The interconnect is isolated from the bottom contact of the first photovoltaic cell by means of the photovoltaic stack and the interconnect is connected to the bottom contact of the second photovoltaic cell in an opening of the photovoltaic stack.

Abstract: A method for manufacturing a thin film solar cell device including a CIGS based thin film solar cell module (17). Edge deletion by selective removal of a multilayer structure (13) that includes at least a front contact (15) and a CIGS layer (7) to expose the back contact (5) in at least a peripheral area (22) in the circumferential region (21) of the module (17) adjacent to a first longitudinal thin film solar cell segment (18) allows for contacting of the module (17) by attaching at least a first contacting element (27) to the back contact (5). Preferably a blasting operation using simultaneous supply of blasting agents and gathering of debris in a blasting chamber (32) arranged on the thin film solar cell module (17) is used for the selective removal.

Abstract: The present invention provides an electrical feed-through (200) for making a durable and reliable electrical connection through a wall (227) of a vacuum chamber (225). The electrical feed-through (200) comprises a tubular member having an open end (217) and a closed end (219). At least one conductor (201) extends through the closed end (217) and is fixed thereto by a vacuum sealing joint (214). The joint (214) is arranged so that it is not in line-of-sight from the open end (217). In this way impinging elements (220) and direct heat radiation (221) is prevented from directly reaching the joint (214), thereby extending the time it takes for contamination of the joint (214) to cause problems.
