摘要:
A solar cell assembly or module comprising a plurality of solar cells mounted on a support, the support comprising a plurality of conductive vias extending from the top surface to the rear surface of the support. Each one of the plurality of solar cells is placed on the top surface with the first contact of a first polarity of the solar cell electrically connected to the first conductive via. A second contact of a second polarity of each solar cell can be connected to a second conductive via so that the first and second conductive portions form terminals of opposite conductivity type. The solar cells on the module can be interconnected to form a string or an electrical series and/or parallel connection by suitably interconnecting the terminal pads of the vias on the back side of the module.

A solar cell assembly comprising a plurality of solar cells (104, 204) and a support, the support comprising a conductive layer. The conductive layer is divided into a first conductive portion (108, 208) and a second conductive portion (107, 207). Each solar cell of the plurality of solar cells comprising a front surface, a rear surface, and a first contact (111) in correspondence with the rear surface. Each one of the plurality of solar cells is placed on the first conductive portion with the first contact electrically connected to the first conductive portion so that the solar cells are connected in parallel through the first conductive portion. A second contact (105, 205) of each solar cell can be connected to the second conductive portion. The two conductive portions serve as busbars of the solar cell assembly.

摘要:
A method of automatically fabricating a rectangular array of series connected solar cells by fabricating a first linear string of series-interconnected solar cells, the first string having a first end and opposite second end; automatically positioning the first string of series-interconnected solar cells on a first position on an assembly fixture; subsequently fabricating a second linear string of series-interconnected solar cells; the second string having a first end and an opposite second end; automatically positioning the second string of series-interconnected solar cells on a second position on the assembly fixture so that the first and second string are arranged parallel and directly adjacent to each other; electrically interconnecting the second end of the first string with the second end of the second string so that the first and second strings are connected in a series electrical circuit; and repeating the above steps to produce a rectangular array.
