An over-soldering prevented tabbing device for manufacturing solar cell modules is disclosed in which the over-soldering is prevented from occurring in the tabbing device for performing the soldering process in manufacturing the solar cell modules. The over-soldering prevented tabbing device according to an embodiment of the present disclosure includes a solar cell module cell that is transported on a conveyor by a unit of cell; a soldering head installed above the solar cell module cell and having a built-in heat source that provides heat to solder the flux coated on the transported solar cell module cell; a driver reciprocating the soldering head in a direction in which the conveyor moves; and a controller controlling the driver.

Photovoltaic cells, methods for fabricating surface mount multijunction photovoltaic cells, methods for assembling solar panels, and solar panels comprising photovoltaic cells are disclosed. The surface mount multijunction photovoltaic cells include through-wafer-vias for interconnecting the front surface epitaxial layer to a contact pad on the back surface. The through-wafer-vias are formed using a wet etch process that removes semiconductor materials non-selectively without major differences in etch rates between heteroepitaxial III-V semiconductor layers.

Provided is a wire transfer apparatus of a tabbing apparatus. A wire transfer apparatus of a tabbing apparatus according to the present invention includes: a first transfer gripper unit configured to grip a wire; a second transfer gripper unit disposed in parallel to the first transfer gripper unit and configured to grip the wire at a location spaced apart from the first transfer gripper unit together with the first transfer gripper unit; and a gripper transfer unit configured to transfer the wire while moving the first transfer gripper unit and the second transfer gripper unit.

A photovoltaic interconnect wire includes a conductive base strip with grooves provided thereon, and the grooves are linear and/or curved strip-shaped grooves (3) arranged obliquely to a longitudinal direction of the conductive base strip. An inclination angle of 15 to 75 is present between each linear strip-shaped groove and the longitudinal direction of the conductive base strip, and between a tangent line of any point on the curve of a curved-shaped groove and the longitudinal direction of the conductive base strip. The photovoltaic soldering strip increases an output power of a solar cell assembly by increasing the total reflection proportion. It also ensures soldering fastness by adjusting flat regions of the base strip. Effective cross section loss of the conductive base strip is reduced by adjusting the angle of each groove, so as to minimize the confluence efficiency loss of the soldering strip.

Compact apparatus for the semi-automatic horizontal assembly of photovoltaic panels with solar cells, made up of a multi-function workstation in the form of a pilot system integrating multiple working and conveying means which carry out the various operations concomitantly and in a coordinated way. On the sides of the working surface there is the loading zone of the cells, the loading zone of the conductive ribbons and a pair of longitudinal rails which are intended to guide two mobile gantries, which roto-translate above the working surface, from one loading zone to the other, being equipped for the purpose of assembly. In particular, the compact apparatus is versatile in use and allows to obtain already in the experimental laboratory phases the levels of accuracy and control of an industrial system, for the purpose of optimizing the product and the assembly technologies reducing wastes and faults.

A solar cell interconnect processing assembly includes a stack of interconnects, a positioning head, and a control system. The positioning head picks up an interconnect from the stack of interconnects at a first location, moves the interconnect from the first location to a second location, heats the interconnect while moving the interconnect from the first location to the second location, and places the interconnect over two adjacent solar cells at the second location. The control system controls a temperature at which the interconnect is heated and controls movement of the positioning head.

Automatic assembly method of a photovoltaic panel with cells of the back-contact type provided with a conductive backsheet with a thermoplastic encapsulating layer; the loading of the cells occurs in combination with their pre-fixing in a combined station sequentially placed before the superimposition of the upper encapsulating layer and after the laying of the conductive adhesive. The loading is carried out with a first device of the automatic mechanical hand type which takes a group of cells, aligns them with the back contacts in correspondence of the holes and lays them vertically from above. Furthermore, a second device of the presser-heater type carries out the pre-fixing of the cells holding them in the final position also with localized heating on at least one portion of each cell in such a way as to activate the adhesive function of the underlying thermoplastic encapsulating layer. A combined loading and pre-fixing station is also disclosed.
