Abstract: The disclosure discloses a photovoltaic cell assembly, a photovoltaic cell array, and a solar cell assembly.

Abstract: The present disclosure provides a solar cell assembly, comprising a front plate, a front glue film layer, a cell piece array, a back glue film layer and a back plate which are sequentially stacked, wherein the front plate comprises glass, a side, deviating from the cell piece array, of the glass is provided with one or more light scattering units, and each light scattering unit is of a sunken structure formed when the side, deviating from the cell piece array, of the glass is sunken inwards towards a side, adjacent to the cell piece array, of the glass. The present disclosure provides that the light scattering unit is not needed to correspond to a non-gate line portion of a cell piece, a requirement for type correspondence of the glass and the cell piece is not high, it is guaranteed that a whole silicon wafer can utilize incident light rays very well, a light receiving area of the glass is increased, assembly power is improved, and assembly installing cost is lowered.
