Annotation: Rapidly increasing energy consumption is a global problem strongly contributing to the excessive use of fossil fuels and climate change. It has encouraged research for renewable energy sources, of which solar energy is the most reliable, sustainable, and long-term alternative. The most rapidly developing and one of the most promising technologies providing grid-free electricity is organic-inorganic hybrid perovskite solar cells, which performance already exceeds those of the commercialized silicon solar panels. However, reference materials used for the organic semiconductor layer of such devices are obtained during a complex synthetic procedure, which leads to a high product cost, hence limited possibilities for large-scale perovskite solar cell manufacturing. Therefore, it is important to find alternative synthetic schemes for hole transporting materials with a minimized number of steps and simple workup procedures. Four new enamine-based series of organic semiconductors were synthesized and investigated in this thesis. These hole transporting materials were obtained using a simple enamine synthesis chemistry, where metal catalysts and difficult purification procedures are not required, which results in a reduced final cost of the semiconductors. In addition, novel enamines were used for the fabrication of perovskite solar cells, which demonstrated high power conversion efficiency values, proving the potential of a novel class of compounds.
