| Abstract |
We report Perovskite solar cell with a high-quality three dimensional Photonic crystal nanostructure embossed in the mesoporous titanium oxide layer. We have developed the mesoporous layer with embossed pattern to enhance the optical properties via the patterning procedure including fabrication of well-designed PDMS master mold with nano-scale patterns and pressure imprinting/stamping PDMS with various imprinted nano-scale structures in the mesoporous TiO2 layer. The effect of photonic crystal with round-shaped of various size show that enhanced optical absorption. The current density is greatly improved while the open-circuit voltage of the cell maintain. As a result, power conversion efficiency was greatly improved. |
