Abstract Developing countries and emerging markets demands for environmental friendly renewable energy sources continuously increases. Renewable energy technology and especially photovoltaics is an alternative solution that gains ground year after year to replace the established carbon consuming energy production methods. One of the latest and of high potential photovoltaics’ generation technology is the so-called perovskite solar cells (PeSCs). A PeSC consists of a laminated structure, which is being developed layer by layer using facile deposition methods onto rigid and flexible substrates. Organic-inorganic hybrid perovskite is a material with the crystal structure AMX3, where A is the organic part, M is the metal and X stands for a halide ion. Since 2009 when the first application of organohalide lead perovskite as the light harvester in solar cells was reported 1, tremendous attention has been devoted to these new types of perovskite-based solid-state solar cells and remarkable power conversion efficiency of over 22% has been achieved up to date2. With respect to its hybrid nature, the material is endowed with high carrier mobility and absorption coefficient, relatively long diffusion lengths and low temperature processing, that renders it ideal for optoelectronic applications. During the implementation of this thesis, the mixed halide perovskite (MAPbI3-xClx) and methylammonium lead triiodide perovskite (MAPbI3) were synthesized and applied as light harvesting material in planar inverted PSCs. In our case the hybrid perovskite semiconductor selected, was deposited using the spin coating deposition technique on top of glass/ITO/(PEDOT:PSS or PTAA) substrate and after that the deposition of an electron transport material followed. To complete the device, thermal evaporation was used to form the silver counter electrode. A variety of factors (annealing temperature of the perovskite, morphology, different HTLs and additives to the hole and electron transport layers) that play a critical role towards the achievement of high and stable power conversion efficiencies (PCEs) were studied and applied.
