SOLAR CELL SHEET, PREPARATION METHOD THEREFOR AND PHOTOVOLTAIC MODULE

Resumen de: EP4697900A2

The present invention provides a solar cell sheet and a preparation method therefor and a photovoltaic module, relating to the technical field of photovoltaics. The solar cell sheet comprises a silicon wafer, a doped polysilicon layer, and grid lines, and a thickness of the silicon wafer at a non-grid-line region in an edge portion of the silicon wafer is greater than a thickness of the silicon wafer at a non-grid-line region in a middle portion. In embodiments of the present invention, since the non-grid-line region of the edge portion has a greater thickness relative to the non-grid-line region of the middle portion, structural strength thereof is better than that of the middle portion. This makes the silicon wafer and the solar cell sheet not prone to warping, micro-cracking, or fragmenting, and not prone to being damaged due to impact. In processing of the solar cell sheet, in assembly of a photovoltaic module, and in subsequent use of the photovoltaic module, a silicon wafer having better reliability can enable the solar cell to have a higher product yield, better performance, and a longer service life.
