Description | Hybrid organic-inorganic nanocomposites are attracting huge interest for range of applications such as solar cells, light emitting diodes and photonics. The ability to control the (i) structural morphology of the hybrid composite and (ii) interface function, are key challenges that have major implications for next generation optoelectronic devices. In this project, we focused on these tasks. Key highlights of this project are: 1) Development of a range of nanocrystal materials with tailored morphology and optical gap. 2) Improving the understanding of the interfacial energetics on electron and hole transfer in organic - inorganic semiconductor films. 3) Improved fundamental understanding of the factors influencing the stability of hybrid organic lead halide perovskite materials and solar cells. In particular, we have reported on the role of light and oxygen on the degradation of methyl ammonium lead triiodide perovskite films and devices. These findings are expected to impact fields beyond solar cells and will also be exploited in different areas, such as new nanomaterial-enabled technologies. |
Exploitation Route | The project team have continued to collaborate and have successfully obtained further EPSRC funding to work on hybrid solar cells and in particular perovskite devices. |
