Development of Advanced Tests for Bio-inspired Hybrid Organic Inorganic Electronic Devices

This thesis describes the management and development of an advanced testing platform for bio inspired hybrid organic-inorganic devices. with the help of external collaborators, perovskite (psc) and dye-sensitized solar cells (DSSC), luminescent solar concentrators (LSC) and neuromorphic organic devices (NOD) working as artificial synapses have been characterized in steady state and transient conditions on the system. The goal of the thesis is to correlate different advances optoelectronic characterization techniques through the use of a single equipment to improve the throughput of device assessment. The thesis is organized into three parts: 1. Steady state characterizations on the three device typologies are performed. JV and IPCE measurements for photovoltaic (PV) devices show the importance of the illumination spectra, which is emphasized by the measurements of photoluminescence for LSCs and absorption dynamics of NODs. 2. Transient analysis has been demonstrated to measure the dynamic behaviour of perovskite devices and correlate it with the improvements in the steady state tests due to the addition of a hole blocking buffer layer to the device stack. 3. A second system was developed for statistical measurements on many devices. As the stability of emerging PV technology is still under development due to fabrication inconsistencies, a high throughput many devices measurement system was developed to improve the statistics focussing on the design of a parallel maximum power point tracker.
