    Abstract: A method of manufacturing a solar cell string according to an embodiment of the present disclosure includes a provisional fixation step in which, at a first position and at a temperature lower than or equal to 50°C, a wiring member (21) is placed over a solar cell (20) with an adhesive (22) therebetween, and the wiring member (21) and the solar cell (20) are provisionally fixed to each other, a transport step in which, after the provisional fixation step, the wiring member (21) and the solar cell (20) are moved to a second position while a state in which the wiring member (21) and the solar cell (20) are provisionally fixed to each other by stickiness of the adhesive (22) is maintained, and a pressure-bonding step in which, at the second position, the adhesive (22) is heated to a temperature greater than or equal to a curing temperature of the adhesive (22) while the wiring member (21) is pressurized, to cure the adhesive (22). A viscosity of the adhesive (22) before being cured, at a temperature of 30°C and a shearing velocity of 0.01/sec., is greater than or equal to 50 Pa·s.

    Abstract: Methods and systems for forming and packaging a roll of photovoltaic cells are provided. A string of photovoltaic cells is incrementally formed such that the photovoltaic cells in the string extend from a leading edge of the string, where incrementally forming the string comprises sequentially connecting successive photovoltaic cells, and where sequentially connecting successive photovoltaic cells comprises connecting each successive photovoltaic cell to a respective, previously-connected photovoltaic cell that is farthest from the leading edge. Bypass diodes are electrically connected to successive portions of the string as the string is being formed. The string is wound with the bypass diodes connected thereto into a roll by rotating the leading edge of the string about a take-up roller as the string is being formed. In response to the string reaching a second predetermined number of photovoltaic cells, the roll is completed and packaged.

    Abstract: Compact apparatus (10) for the semi-automatic horizontal assembly of photovoltaic panels (200) with solar cells (112), 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 (100) 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 (120, 130), which roto-translate above the working surface, from one loading zone to the other, being equipped for the purpose of assembly. In particular, said compact apparatus (10) 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.
