The present invention relates to a photovoltaic module comprising at least two solar cells, which are spaced apart from each other by cell intervals; bus bars and/or grid lines over the at least two solar cells; and front side cover plate glass which is arranged above the bus bars and/or the grid line. The photovoltaic assembly is characterized in that the upper surface of the front side cover plate glass is provided with a local structure with the haze of at least 50%, and the local structure is located in a part of or all projection areas corresponding to the bus bars, the grid lines, the cell intervals or combinations of the bus bars, the grid lines and the cell intervals. The photovoltaic module provided by the invention has higher redirect light transmittance, so that the power outputof the photovoltaic module can be remarkably improved. The invention further discloses a simple and easy method for preparing the photovoltaic module.
