Abstract
A layer stack for thin-film photovoltaic modules includes a back electrode, an absorber, a buffer/i-layer, a front electrode and an interlayer which are sequentially stacked on a corresponding substrate from bottom up by vacuum coating deposition. The layer stack is divided by P1, P2 and P3 structure lines respectively. A conductive metal grid is embedded in the layer stack, and the metal grid is deposited on the buffer/i-layer before or after the P2 structure line. According to the present invention, the conductive metal grid is embedded in the layer stack, and the metal grid is deposited on the buffer/i-layer before or after the P2 structure line, thereby forming an embedded grid, and thus, the front electrode and the interlayer can be deposited without breaking vacuum in the process sequence. The embedded grid reduces capital expenditure and operating cost.
