Abstract
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 () have the same polarity, back electrodes of the plurality of first type of solar cells () also have the same polarity, and the polarity of the front electrodes of the first type of multiple solar cells () is opposite to the polarity of the back electrodes. Back electrodes on a back side of the second type of solar cell () 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.
