Abstract |
Perovskite solar cells attract much interest in photovoltaic applications nowadays, due to the high solar cell performance that they exhibit combined with the relatively ease of fabrication. Moreover, III-V nanowires, as for example GaAs nanowires also consist a matter of research due to their excellent optoelectronic properties, such as high mobility of carriers and optimum bandgap. Moreover, the reduced cost of fabrication is another advantage of nanowires. Due to their properties, e.g. GaAs nanowires could be used as an Electron Transporting Material (ETM) in perovskite solar cells, replacing conventional ETMs, like titanium dioxide (TiO2). Compared to TiO2, GaAs has significantly higher electron mobility value. Moreover, the energy levels of intrinsic GaAs favor band alignment of GaAs conduction band with the LUMO orbital of CH3NH¬3PbI3 perovskite. So, effective electron extraction can be achieved. Thus, GaAs nanowires could be a better choice as an ETM in perovskite solar cells. In the present thesis, hybrid GaAs nanowire/perovskite solar cell devices were fabricated. Moreover, optical characterization of the samples was accomplished.
