Sumario:Halide perovskites (HPs) have been demonstrated as promising materials for the preparation of efficient solar cells, LEDs and other optoelectronic devices. In addition, HPs can be prepared using low-cost techniques. However some issues such as low stability or hysteresis are hindering their commercialization. As illustrated, combining materials with different natures has been a successful strategy to develop new materials with enhanced properties. In this Doctoral Thesis we analysed the interaction of HPs with other materials, looking for the potential application. The results pointed out that (1) proper preparation of ETMs can significantly improve both the performance and long term stability of solar cells. (2) Better HP film quality can be achieved by combining HP with either QDs or organic molecules, resulting an enhancement in the device performance of solar cells, LEDs and light amplifiers. (3) New property, exciplex emission, can be obtained from the combination of HP and QDs.
