Optimization of photocathode by adding NiO blocking Layers for Tandem DSSCs |
| 초록 |
The photovoltaic performance of tandem pn-dye-sensitized solar cells (pn-DSCs) has been limited by the poor performance of the available p-DSCs. A simplistic method of introducing a compact NiO blocking layer into a poor performing photocathode network of p-DSCs and pn-DSCs is presented to improve the photovoltaic performance using a cobalt-based redox mediator. For the photoelectrodes, we have selected well known SQ and P1 dyes for n-DSC and p-DSC, respectively, which showed a complementary nature in absorbing solar irradiation at different wavelengths. resulting in an overall photovoltaic performance of 1.486%. This performance is further improved to 1.913% by the introduction of an optimized NiO blocking layer to the photocathode. |
