“…QDs have attracted considerable interest due to their excellent properties, such as high extinction coefficient, bandgap tunability, and high potential for efficient multiple exciton generation (MEG) [104][105][106]. The bandgap tunability and MEG of QDs are particularly useful properties for solar cell application.…”

Abstract:The unique optical properties possessed by plasmonic noble metal nanostructures in consequence of localized surface plasmon resonance (LSPR) are useful in diverse applications like photovoltaics, sensing, nonlinear optics, hydrogen generation, and photocatalytic pollutant degradation. The incorporation of plasmonic metal nanostructures into solar cells provides enhancement in light absorption and scattering cross-section (via LSPR), tunability of light absorption profile especially in the visible region of the solar spectrum, and more efficient charge carrier separation, hence maximizing the photovoltaic efficiency. This review discusses about the recent development of different plasmonic metal nanostructures, mainly based on Au or Ag, and their applications in promising third-generation solar cells such as dye-sensitized solar cells, quantum dot-based solar cells, and perovskite solar cells.

“…Las disoluciones coloidales de nanocristales o nanopartículas son interesantes para el proceso de fabricación de dispositivos optoelectróni-cos basados en materiales orgánicos, como por ejemplo, en células solares [1], [2], [3], amplificadores de fibra óptica [4] o diodos emisores de luz [5] - [6]. Esto es debido a que la inclusión de los nanocristales modifica las propiedades ópticas de los polímeros conductores, Polivinil Carbanzol (PVK), Poli(3-hexiltiofeno-2,5-diol) (P3HT), Phenyl-C61-Butyric-Acid-Mehtyl Ester (PCBM) [7].…”

RESUMENEn el siguiente estudio se realizó la síntesis de nanopartículas de CdS recubiertas por dos tipos de radicales orgánicos, 1-Decanotiol y Tiofenol, mediante dos métodos sencillos. Las nanopartículas se caracterizaron mediante absorción óptica y fotoluminiscencia. Como resultado se observó que dichos nanocristales poseen las características propias de puntos cuánticos y que la mezcla de recubrimientos orgánicos empleada en la síntesis de nanopartículas de CdS afecta a sus propiedades ópticas.Palabras clave: Nanocristales, CdS, recubrimientos mixtos, 1-decanotiol, tiofenol.

In this study, a solar cell with a glass/ITO/CdS/PbS/Al structure was constructed. Both window (CdS) and absorption (PbS) layers were deposited by chemical bath deposition (CBD) method. The CdS window layer was deposited on ITO-glass. The PbS nanocrystalline thin film was prepared with and without triethanolamine on CdS films at bath temperature of 25°C. CdS and PbS nanocrystals were identified using XRD and SEM. The cells are photosensitive in a large spectral range (at visible and near infrared regions). The cell with absorbing layer obtained from the bath without TEA has higher efficiency with the following parameters: the open circuit voltage (V oc ) is 275 mV, short circuit current (J sc ) is 12.24 mA/cm 2 , maximum voltage (V max ) is 165 mV and maximum current (J max ) is 7.11 mA/cm 2 with the efficiency η = 1.31 %, fill factor FF is 32 % under the illumination intensity of 90 mW/cm 2 . The cells have an area of 0.15 cm 2 .
