Abstract

The perovskite solar cell has been the standard when it comes to organic solar cells, a steadily increasing renewable energy source which is greener than its silicon counterpart. However, even if there have been some advances such as overpassing the PCE threshold of 25% and being close to competing with silicon solar cells (PCE = 26.8% in a silicon heterojunction structure), there are still some issues in operability, more specifically the conductivity and stability, amongst others. One of the main parts of the perovskite solar cell which is proven to be causing some of the problems is the hole transport material. As well as finding new compounds which can act as competitive hole transporters, which have been proven difficult, methods of deposition of said molecules into ITO and/or FTO prior to device creation has been observed to contribute to the increase of these setbacks due to the formation of charge traps, uneven interstitial surface and poor homogeneity, amongst others. Self – assembled monolayers (molecules) (SAMs) used as hole transport materials have overcome some of these obstacles, although alternative deposition methods are still required.

This thesis describes a strategy for deposition of hole transport materials in the form of electropolymerisation. We have investigated the electropolymerisation of some hole-transporting materials and investigated the conductivity of their films.
