Provided herein is a sunlight generated power device having an upper fixing frame, a lower fixing frame, a main link, and a sub link, which together form a four bar link, and an actuator. The power device may be used to form a photovoltaic module installed at a building, bridge, park, and the like. Solar cell panels positioned on the power device are easily adjustable to enhance photovoltaic efficiency. The power device may also be constructed to display a luxurious image by providing an elegant appearance.

The present invention relates to a building integrated photovoltaic (BIPV) system, and more specifically, to a photovoltaic blind window having a photovoltaic cell applied to an electric blind. The photovoltaic blind window of the invention comprises: a multilayered glass composed of a pair of plate glass sheets that are connected to each other with a spacer to form an inner space between the plate glass sheets; an electric blind placed in the inner space of the multilayered glass, the blind having a plurality of slats elevating or tilting by the rotation of a drive motor; a plurality of photovoltaic cells arranged on at least one side of the slat; and a storage battery for storing electricity that is generated by the photovoltaic cells.

The present invention relates to a method and apparatus for manufacturing a solar cell module using a laser. In the present invention, a tabbing process for bonding a solar cell and metal electrodes is performed by a local irradiation with a laser, so that the heating area can be localized only to a required zone (bonding area) for the tabbing process, thereby minimizing a direct heating zone which occurs in the process. Therefore, it is possible to reduce the damage such as cracks and breakage due to thermal expansion/contraction of a solar cell which is conventionally configured to have a multi-layered structure made of different materials, to improve the bonding strength and the bonding uniformity, and to reduce the processing time, thereby improving the production efficiency.
