ZnO-Based Dye-Sensitized Solar Cells
TL;DR: In this article, a change of focus of the current research on ZnO-based DSCs (from morphology to surface control) is suggested and the origin of this striking difference in performance is analyzed and discussed with the perspective of future applications of ZnOs in dye-sensitized solar cells and related devices.

Determination of carrier density of ZnO nanowires by electrochemical techniques
Iván Mora-Seró,Francisco Fabregat-Santiago,Benjamin Denier,Juan Bisquert,Ramón Tena-Zaera,Jamil Elias,Claude Lévy-Clément +6 more
TL;DR: In this article, the carrier density of ZnO nanowires has been determined by means of electrochemical impedance spectroscopy, and a model taking into account the geometry of the NN wires has been developed and the differences with the standard flat model, as curved Mott-Schottky plots, are discussed.
Journal ArticleDOI
Implications of the negative capacitance observed at forward bias in nanocomposite and polycrystalline solar cells.

TL;DR: The experiments suggest a universality of the underlying phenomenon giving rise to this effect in a broad range of solar cell devices, and an equivalent circuit model is suggested to explain the impedance and capacitance spectra.

Organo-metal halide perovskite-based solar cells with CuSCN as the inorganic hole selective contact
S.D. Chavhan,Oscar Miguel,Hans-Jürgen Grande,Victoria González-Pedro,Rafael Sánchez,Eva M. Barea,Iván Mora-Seró,Ramón Tena-Zaera +7 more
TL;DR: In this paper, a cost-competitive hole selective contact for the emerging organo-metal halide perovskite-based solar cells is proposed, where the CuSCN films have been deposited by a solution casting technique, which has proven to be compatible with the perovsite films, obtaining planar-like heterojunction-based glass/FTO/TiO2/CH3NH3PbI3−xClx/CuSCN/Au solar cells with a power conversion efficiency of 6.4%.
