Figure 4From: Efficient PbS/CdS co-sensitized solar cells based on TiO2 nanorod arraysPhotovoltaic performance of PbS/CdS co-sensitized solar cells. (a) Photocurrent density-voltage characteristic for only CdS-sensitized solar cell and (b) only PbS-sensitized solar cell. (c) Photocurrent density-voltage characteristic for PbS/CdS co-sensitized solar cells with different PbS SILAR cycles.Back to article page
