The development of visible-light active photocatalysts is a current challenge especially energy and environmental-related fields. Herein, methylammonium lead iodide perovskite (MAIPb) was chosen as the novel semiconductor material for its ability of absorbing visible-light. An easily reproducible and efficient method was employed to synthesize the as-mentioned material. The sample was characterized by various techniques and has been used as visible-light photocatalyst for degradation of two model pollutants: rhodamine B (RhB) and methylene-blue (MB). The photo-degradation of RhB was found to achieve about 65% after 180 min of treatment. Moreover, the efficiency was enhanced to 100% by assisting the process with a small amount of H2O2. The visible-light activity of the photocatalyst was attributed to its ability to absorb light as well as to enhance separation of photogenerated carriers. The main outcome of the present work is the investigation of a hybrid perovskite as photocatalyst for wastewater treatment.

“…A pesar de que los materiales basados en estructura de PS fueron estudiados extensamente durante lasúltimas décadas, el primer precedente La baja energía de unión de los excitones (∼ 6 meV a 300 K) siendo menor que la energía térmica a temperatura ambiente (k T ∼ 25 meV) lo que significa que la mayoría de los excitones son disociados térmicamente, 127 además, el proceso simple de producción, la facilidad de producir dispositivos a bajas temperaturas, el bajo coste y la abundancia de materia prima hacen estos materiales tan atractivos. 128 Sin embargo, la baja estabilidad a largo plazo sumada a la inestabilidad térmica y la gran sensibilidad de los dispositivos a la humedad dificultan su comercialización. 129 La reducción de la dimensionalidad de las PS, ha sido una ingeniosa alternativa para solucionar ambos problemas con granéxito.…”

En la presente tesis doctoral, los diodos emisores de luz verde han sido preparados mediante el uso de nanopartículas de perovskita totalmente inorgánicas CsPbBr 3 que fueron sintetizadas a temperatura ambiente y mediante el método tradicional hot-injection. xi AbstractThe increase in energy consumption has caused a great environmental impact due to the intense use of non-renewable energy sources, causing climate changes and global warming. To curb these unwanted effects it is necessary to use and improve renewable energy sources in addition to using devices with lower energy consumption.In the last ten years numerous studies have been carried out on perovskite solar cells, although very efficient, their instability hinders their commercialization. The reduction of the dimensionality of the perovskite is an alternative to improve the stability of these devices.The use of anilinium as an organic cation in the synthesis of perovskites 2D/3D has been reported for the first time in this work highlighting the quality of the material that has significantly better photovoltaic and optoelectronic properties with respect to the perovskite 2D/3D synthesized with butylammonium, which It is one of the most studied materials so far.Subsequently, he focused on the manufacture of a second generation of solar cells based on 2D/3D perovskite using anilinium as bulky cation by the hot-casting method. The positive effect of temperature on the properties of the materials was demonstrated by a direct correlation between temperature, crystal size and PCE. Solar cells with 7.63 % efficiency were obtained with J sc of 13.79 mA/cm 2 . In addition, stability studies showed that films based on a 2D/3D perovskite made with anilinium showed a resistance moderately higher than environmental conditions compared to solar cells based on 3D perovskites.On the other hand, light-emitting quantum dots were synthesized that cover the entire visible spectrum with high quantum yields of fluorescence and color purity, and with them, light-emitting diodes of single color, high brightness and quantum efficiencies were produced. 0.39 %, 1.04 %, 2.10 % and 1.30 % for light emitting diodes based on quantum dots emitting red, orange, green and blue light, respectively.In addition, the white light-emitting diodes were prepared by mixing quantum dots, red-green-blue and orange-green-blue, these showed color temperatures of 5300 K and color rendering index greater than 80 %. Colloidal nanocrystals are excellent candidates for the preparation of electroluminescent devices as well as high quality displays.Perovskite nanoparticles that have been extensively studied for optoelectronic applications were also synthesized due to their extremely high photoluminescence quantum yield, tunable bandwidth and exceptionally narrow emission spectra. Therefore, perovskite nanoparticles also have an enormous potential for the development of high efficiency color screens, low cost and wide range of colors with high purity.However, its synthesis typically involves processes at...
