Abstract:
A solar module is disclosed. The solar module includes a back sheet, a transparent substrate, a plurality of solar cells disposed between the back sheet and the transparent substrate, and an encapsulant for fastening the solar cells therebetween. The back sheet includes a light-receiving surface facing the solar cells, and a back surface opposite to the light-receiving surface. The reflectivity of the light-receiving surface is greater than 90%, and the reflectivity of the back surface is less than 10%. Therefore, the back sheet can have high reflectivity and high thermal radiation rate.
Abstract:
An apparatus for patterning a ribbon includes a holding device, a heating device, and an embossing device. The holding device is utilized for positioning the ribbon on a surface of a solar cell. The first solder layer contacts the solar cell. The heating device is utilized for melting the ribbon for string tabbing on the solar cell. The embossing device is utilized for contacting the melted ribbon to form a pattern on the ribbon. A surface energy between the ribbon and the solar cell is greater than a surface energy between the ribbon and the embossing device.
Abstract:
A photovoltaic device provided in the present disclosure includes a superstrate, a lower substrate, a plurality of photovoltaic cells and a package structure. The superstrate is light-transmissive, and arranged in parallel with the substrate. The photovoltaic cells are disposed side-by-side at intervals with each other between the superstrate and the substrate, and a gap zone is defined by two facing lateral surfaces of every two of the neighboring photovoltaic cells. The package structure is sandwiched between the superstrate and the substrate, and encapsulates the photovoltaic cells between the superstrate and the substrate in which a reflection portion is provided in the package structure, and located in the gap zone for reflecting lights from the superstrate back to the photovoltaic cells.
Abstract:
A solar panel includes a substrate, plural solar cells, wires, and plural bypass diodes. The substrate includes a bottom area, a middle area, and a top area vertically arranged from bottom to top. The middle area includes a first zone, a second zone and a third zone horizontally arranged from left to right. The solar cells are disposed on the substrate in columns and in rows. The bottom area includes at least two rows of the solar cells. The top area includes at least two rows of the solar cells. The wires serially connect the solar cells. The bypass diodes are disposed on the substrate, in which each of the first zone, the second zone, the third zone, the bottom area and the top area is disposed with at least one of the bypass diodes.
Abstract:
A photovoltaic apparatus includes N solar cell modules. The solar cell module includes a first sub-loop, a second sub-loop, and at least one junction box. Each of the first sub-loop and second sub-loop has a first end and a second end. The junction box is electrically connected to the first ends and the second ends and connected to another junction box in another adjacent solar cell module. N is a natural number.
