Capacitive Dark Currents, Hysteresis, and Electrode Polarization in Lead Halide Perovskite Solar Cells

Osbel Almora, +6 more
- 16 Apr 2015 - 
TL;DR: Current-voltage curves and capacitive responses of perovskite-based solar cells are connected and the observed hysteretic effect in the dark current originates from the slow capacitive mechanisms.
Journal ArticleDOI

Surface Recombination and Collection Efficiency in Perovskite Solar Cells from Impedance Analysis.

Isaac Zarazua, +8 more
- 01 Dec 2016 - 
TL;DR: The large diffusion lengths recurrently measured in perovskite single crystals and films signal small bulk nonradiative recombination flux and locate the dominant carrier recombination processes at the outer interfaces, enabling a comparison among different structures, morphologies, and processing strategies of passivation and buffer layers.
Journal ArticleDOI

Light-Induced Space-Charge Accumulation Zone as Photovoltaic Mechanism in Perovskite Solar Cells

Isaac Zarazua, +3 more
- 21 Jan 2016 - 
TL;DR: It is concluded that the large photovoltage and capacitance are associated with electronic accumulation zone at the interface with the metal oxide contact.
Journal ArticleDOI

Noncapacitive Hysteresis in Perovskite Solar Cells at Room Temperature

Osbel Almora, +4 more
- 06 Jun 2016 - 
TL;DR: In this article, the authors distinguish between capacitive and non-capacitive currents giving rise to specific hysteretic responses in the J-V curves of perovskite solar cells.
Journal ArticleDOI

Effect of Different Sensitization Technique on the Photoconversion Efficiency of CdS Quantum Dot and CdSe Quantum Rod Sensitized TiO2 Solar Cells

Diego Esparza, +8 more
- 09 Jun 2015 - 
TL;DR: The effect of three different sensitizing methods in the final cell performance was analyzed in this paper, where the TiO2 electrodes were sensitized with CdS and CdSe by electrophoretic and pipetting respectively, while for the sensitizer with both techniques the efficiency was 4.7%.
