Organic electronic devices, such as an organic light emitting diodes, an organic thin-film transistors, an organic sensing devices and an organic solar cells (OSCs) are widely studied. Especially in OSCs, one of the most interesting topics is an organic-inorganic hybrid perovskite solar cell (PeSC) due to their excellent photoelectric conversion efficiency along with their low material costs, and its recorded power conversion efficiency. In this situation, we have studied an electron beam evaporation (EBE) of titanium dioxide (TiO₂) layer for the electron-transport layer for the PeSC. In this time, we have investigated the preliminary evaluation of organic-related perovskite photo-sensors (PePS) by applying reverse-biased voltage to collect the photo-generated carrier for light sensing applications.
