Capacitive dark currents, hysteresis, and electrode polarization in lead halide perovskite solar cells
Almora Rodríguez, Osbel; Zarazúa, Isaac; Mas, Elena; Mora-Sero, Ivan; Bisquert, Juan; Garcia-Belmonte, Germà American Chemical Society (2015-04)Despite spectacular advances in conversion efficiency of perovskite solar cell many aspects of its operating modes are still poorly understood. Capacitance constitutes a key parameter to explore which mechanisms control ... -
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 ... -
