“…In recent years, high-flux solar simulators (HFSSs) have gained importance for the development of CSP components and systems as they offer a fully controllable and constantly available testing environment at lower costs than using a fullscale solar platform [23] [24]. A recent review of solar simulators [25] showed that 26 HFSSs of various designs were in operation in late 2016 with 7 of them capable of providing a radiative power of more than 15 kW and 3 capable of providing more than 30 kW at the focal plane. In early 2017 another HFSS was completed offering radiative power of up to 310 kW [26].…”

“…In early 2017 another HFSS was completed offering radiative power of up to 310 kW [26]. With the vast majority of the operational HFSSs delivering a radiative power below 30 kW [25] the main challenge of HFSS testing is caused by the fact that the radiative power delivered is lower than the power available at a full-scale CSP system. Additionally, differences of the peak flux and the spatial flux distribution can appear between HFSSs and full-scale systems.…”

We present the design and characterization of a high flux solar simulator (HFSS) based on metal halide lamps and built from commercially available components. The HFSS that we present was developed to support the evaluation of a solar thermochemical reactor prototype. The HFSS consists of an array of four independent lamp/reflector modules aimed at a common target location. Each module contains one 2500 We lamp and one electroformed ellipsoidal reflector having an interfocal distance of 813 mm. The modules are oriented with an angle relative to the target surface normal vector of 24.5 deg. Design simulations predicted that the peak flux of this HFSS would be 2980 kWth/m2, with a total power delivered to a 6-cm target of 3.3 kWth, for a transfer efficiency of 33.3%. Experimental characterization of the HFSS using optical flux mapping and calorimetry showed that the peak flux at the focal plane reached 2890±170 kWth/m2, while the total power delivered was 3.5±0.21 kWth for a transfer efficiency of 35.3%. The HFSS was built at a material cost of ∼$2700.00/module and a total hardware cost of ∼$11,000.00 for the four-lamp array. A seven-lamp version of this HFSS is predicted to deliver 5.6 kWth to a 6 cm diameter target at a peak flux of 4900 kWth/m2 at a hardware cost of ∼$19,000.00 ($3400.00/kWth delivered, $1100.00/kWe).

“…Este concepto está relacionado con la longitud del caminoóptico que la radiación solar directa tiene que viajar a través de la atmósfera y por lo tanto a la posibilidad de interacción con moléculas de gases atmosféricos y aerosoles: cuanto mayor es el camino, mayor es la cantidad de radiación atenuada debido a la interacción con la materia. 152 Las AM pueden ser calculadas sin ninguna medida, ya que depende sólo de la ubicación geográfica y del tiempo, y se define como una función delángulo del cenit solar, θ: 152, 153…”

“…Por convenio, se atribuye un AM igual a 0 a la radiación solar extraterrestre. 152,153 Para estandarizar las medidas, es decir, para que los dispositivos puedan ser medidos en cualquier parte del mundo y proporcionar los mismos resultados se utilizan simuladores solares y así lograr mejor reproducibilidad y confiabilidad de las curvas J-V.

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...
