The present invention discloses a solar cell assembly including a back contact type solar cell and an insulating bonding tape. The back contact type solar cell includes a substrate, a first conductivity type doping layer, a second conductivity type doping layer, a first electrical contact and a second electrical contact. The first conductivity type doping layer is arranged onto the substrate. The second conductivity type doping layer is arranged on the substrate and adjacent to the first conductivity type doping layer. The first electrical contact is connected with the first conductivity type doping layer and keeps distance from the second conductivity type doping layer. The second electrical contact is connected with the second conductivity type doping layer and keeps distance from the first conductivity type doping layer. The insulating bonding tape is provided with a through hole and is attached to the substrate. At least part of the insulating bonding tape is disposed to the first conductivity type doping layer, and the through hole of the insulating bonding tape is exposed out of the first electrical contact or the second electrical contact. With adoption of the insulating bonding tape, short circuits caused by overflow of conductive glue can be effectively avoided, and failures caused by glue overflow of the back contact type solar cell are prevented.
Description
technical field [0001] The invention relates to the field of solar cells, in particular to a solar cell assembly and a solar cell module with the function of preventing glue overflow. Background technique [0002] Since all the electrode contacts and all semiconductor doped layers of the back contact solar cell are concentrated on the back of the solar cell, the light-receiving surface of the back contact solar cell will not be shielded by the solder ribbon. In this way, the light-receiving area of the back-contact solar cell can be increased, thereby improving the photoelectric conversion efficiency of the back-contact solar cell. [0003] However, since all electrode contacts and all semiconductor doped layers of a back contact solar cell are concentrated on the back of the solar cell, the distance between the electrode contacts of different potentials and the semiconductor doped layer is relatively short, so in When connecting back-contact solar cells in series, the co...
