New Materials and Processing Routes for Photovoltaics

In the following thesis, conjugated polymers and perovskite semiconductors are studied for the use in photovoltaic devices, including the photophysical properties and crystallographic analysis on a new low-dimensional perovskite material. A potential scale-up technique that utilises an ultrasonic spray-coating mechanism was also employed with a precursor additive, significantly improving the overall crystalline qualities and optoelectronic properties.
