Figure 5: (a-b) The evolution in passivation quality (iVoc) after specific steps of single side textured (SST) and double side textured (DST) solar cells fabrication: (1) annealing, (2) hydrogenation, (3) TCO deposition and (4) hydrogen annealing; (c-d) certified current-voltage and power-voltage curves of the best SST and DST poly-SiOx passivated c-Si solar cell. Sketches of SST and DST solar cells are reported in Figure 2.
