| Outline of Final Research Achievements |
Supercapacitors and high-efficiency photovoltaics based on solution-processable thin film materials are desirable for sustainable energy at reduced cost of material and fabrication. Both of these applications make use of highly porous electrode surfaces. In this research, we have developed some unique methodologies to obtain mesoporous TiO2 layer which have application in both of these applications. In the case of perovskite solar cells, using a facile sol gel technique loading a general polymer PMMA as a templating agent, we were able to control porosity and the resulting effect on device performance. The perovskite solar cells based on PMMA-mediated mesoporous TiO2 achieved a device efficiency of 12.6%, which is 2.8 times higher than a control sample. We believe this facile sol gel technique with a simple polymer additive has the great potential to contribute significantly toward the development of low-cost miesoporous electrodes for energy storage and generation from sunlight.
