Solar cell having edge collection electrode and solar cell module comprising same
The present invention relates to a solar cell having an edge collecting electrode and a solar cell module comprising the same, the solar cell being capable of preventing a cell crack phenomenon caused by an interconnector and improving an adhesive characteristic of the interconnector by dividing a planar area of the solar cell into a main area and an edge area and positioning the outermost contact point of the interconnector at a boundary between the main area and the edge area, and being capable of improving carrier collecting efficiency by arranging, in the edge area, the edge collecting electrode and the branched electrode which are physically separated from the interconnector.

SOLAR CELL MODULE ON FLEXIBLE SUPPORTING FILM
A solar cell module comprising a plurality of solar cells mounted on a flexible support, the support comprising a conductive layer on the top surface thereof divided into two electrically isolated portions—a first conductive portion and a second conductive portion. Each solar cell comprises a front surface, a rear surface, and a first contact on the rear surface and a second contact on the front 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 through the first conductive portion. A second contact of each solar cell is then connected to the second conductive portion by a respective interconnect.
Solar cell string, string group, module, and manufacturing method thereof
Disclosed is a solar cell string, a string group, a module, and a manufacturing method thereof. The solar cell string is formed by connecting a plurality of first type of solar cells and at least one second type of solar cell, wherein front electrodes of the plurality of first type of solar cells (701) have the same polarity, back electrodes of the plurality of first type of solar cells (701) also have the same polarity, and the polarity of the front electrodes of the first type of multiple solar cells (701) is opposite to the polarity of the back electrodes. Back electrodes on a back side of the second type of solar cell (801) comprise a positive electrode and a negative electrode. The solar cell string utilizes two structures of solar cells to establish a stacked connection of shingles, thereby enabling a current carrying unit to direct current out of the back side of the solar cells, making it easier to incorporate a diode, causing no size increase in the module area, reducing the wafer breakage rate, and accordingly raising the module pass rate and assembling efficiency. Further disclosed is a string group formed by the solar cell string, a module, and a manufacturing method thereof.
