Annotation: To compete in the electricity market, the photovoltaic technology needs to be further improved with the anticipated possibility to complement silicon-based devices. The currently emerging solar cell (SC) technologies based on perovskite or metal chalcogenide are not yet commercially viable. However, they have demonstrated numerous evident advantages over silicon solar cells. The efficiency of these SCs is strongly dependent on the type of the semiconductor selected as the electron transporting material (ETM). So far, new p-type semiconductor self-assembled molecules (HTM SAMs) are being rapidly investigated, and the effort devoted towards designing new ETMs is significantly less prominent. Accordingly, the choice of efficient ETMs is significantly more limited if compared with a large variety of HTMs analogues. The field of organic ETMs is dominated by fullerene and its functionalized derivatives which are being used in different SCs. Nevertheless, their difficult synthesis and purification, high product cost and limited modification options hinder their applicability in devices. A combination of the current challenges in the development of ETMs and the success of the HTM SAM concept in perovskite SCs was an important factor to put more effort into the investigation of new ETMs which could be able to form monolayer as well. Furthermore, the strategy to incorporate ETM SAMs in photovoltaic devices is not widely developed, thereby indicating that there is still a lot of room for the synthesis and investigation of new ETM SAMs. Various chromophores functionalized with different anchoring groups and their prospective applicability as ETM SAMs in the antimony chalcogenides and perovskite SCs are described in this thesis.
