PROCESS FOR MONOLITHIC SERIES CONNECTION OF THE PHOTOVOLTAIC CELLS OF A SOLAR MODULE AND A PHOTOVOLTAIC MODULE OBTAINED BY SAID METHOD

摘要

The invention relates to a process for manufacturing two photovoltaic cells (12, 14) connected in series, which process comprises: producing an insulating substrate (32); forming a multilayer comprising - a first conductive layer (30) formed on the substrate (30), a semiconductor layer (36) comprising a first absorbing layer (38) and a second semiconductor layer (40) forming a junction with the first absorbing layer (38), and a second transparent conductive layer (44) formed on the absorbing layer (36); and forming a region (78) that divides the multilayer into two cells (12, 14) connected in series by an electrical path. The formation of said path comprises: forming a first trench (70) down to the substrate (32); forming a second trench (72) down to the first conductive layer (30); and depositing a conductive solution (76) into the first trench (70) and at least into a portion of the second trench (72) such that the solution (76) that penetrates into the first trench (70) does not reach the first conductive layer (30) and the solution (76) that penetrates into the second trench (72) reaches the first conductive layer (30).
