The advent of new telecommunication technologies such as 5G and 6G, as well as the strong development of the Internet of Things (IoT) require more efficient communication systems that are able to provide high data rates and high service quality. These developments are coupled with an ever-increasing need for electrical energy supply. In this context, integrating a low cost solar cell as simultaneous data receiver and energy harvester in optical wireless communication systems (OWC) is one of the most relevant approaches to address this challenge. Emergent solar cell technologies such as perovskite solar cells can be well-adapted for such applications, considering their low cost, high efficiencies in indoor environment, light weight and flexibility. This thesis work aims at studying the dynamic behavior of perovskite solar cells, using impedance spectroscopy, and at discussing its relation with their photovoltaic performances. We especially study the dynamic response of various mixed cations and mixed halide perovskite absorbers, thanks to their outstanding power conversion efficiency, their relatively easy processing from solution, and their suitable stability in ambient conditions. In particular, based on the simulation of the experimental impedance of the devices, we discuss the specific physical process governing their low frequency and high frequency response, and the relation with the achievable bandwidths when used as receiver for OWC applications. We more directly illustrate the possibility to tune the response time of the devices through the architectures (interfacial and active layer properties). Significant improvement in bandwidth can be achieved, suggesting strong potentialities for future applications.
