Effect of Different Sensitization Technique on the Photoconversion Efficiency of CdS Quantum Dot and CdSe Quantum Rod Sensitized TiO2 Solar Cells
Esparza, Diego; Zarazúa, Isaac; López-Luke, Tzarara; Cerdán Pasarán, Andrea; Sánchez Solís, Ana; Torres Castro, Alejandro; Mora-Sero, Ivan; De la Rosa, Elder American Chemical Society (2015-06)The procedure employed for the sensitization of mesoporous photoanodes affects strongly the final performance of sensitized devices, especially when semiconductor quantum dots and quantum rods are used as sensitizers. In ... -
Effect of the electrophoretic deposition of Au NPs in the performance CdS QDs sensitized solar cells
Zarazúa, Isaac; Esparza, Diego; López-Luke, Tzarara; Ceja-Fernández, A.; Reyes-Gomez, J.; Mora-Sero, Ivan; Rosa, Elder de la Elsevier (2016)Solution-processed mesoscopic oxide semiconductor-based materials offer potentially low-cost and high stability alternative for next generation of solar cells, and metallic nanoparticles had shown to be a good alternative ... -
Enhanced Photovoltaic Performance of Mesoscopic Perovskite Solar Cells by Controlling the Interaction between CH3NH3PbI3 Films and CsPbX3 Perovskite Nanoparticles
Sidhik, Siraj; Esparza, Diego; Martínez-Benítez, Alejandro; López-Luke, Tzarara; Carriles, Ramon; Mora-Sero, Ivan; De la Rosa, Elder American Chemical Society (2017-02)We report the incorporation of all-inorganic highly stable CsPbX3 (X = I, Br) based perovskite nanoparticles (NPs) on top of a bulk CH3NH3PbI3perovskite thin film. This design utilizes the photogeneration ability of ... -
Enhancement of Efficiency in Quantum Dot Sensitized Solar Cells Based on CdS/CdSe/CdSeTe Heterostructure by Improving the Light Absorption in the VIS-NIR Region
Esparza, Diego; López-Luke, Tzarara; Oliva, Jorge; Cerdán Pasarán, Andrea; Martínez-Benítez, Alejandro; Mora-Sero, Ivan; De la Rosa, Elder Elsevier (2017-09-01)In this work, we demonstrate an enhancement of photocurrent in QDSSCs based on CdS (QDs)/CdSe Quantum rods (QRs)/CdSeTe (QDs) heterostructure due to the increased photon harvesting in the VIS-NIR region. The photo-conversion ... -
Operating Mechanisms of Mesoscopic Perovskite Solar Cells through Impedance Spectroscopy and J-V Modeling
Zarazúa, Isaac; Sidhik, Siraj; López-Luke, Tzarara; Esparza, Diego; De la Rosa, Elder; Reyes-Gomez, J.; Mora-Sero, Ivan; Garcia-Belmonte, Germà American Chemical Society (2017-11)The performance of perovskite solar cell (PSC) is highly sensitive to deposition conditions, the substrate, humidity, and the efficiency of solvent extraction. However, the physical mechanism involved in the observed changes ...
