Dye-sensitized solar cells (DSCs) have emerged in the photovoltaic scenario as one of the
most promising low-cost alternative to the most employed solar devices based on silicon …

A multitude of chemical, biological, and material systems present an inductive behavior that
is not electromagnetic in origin. Here, it is termed a chemical inductor. We show that the …

Impedance spectroscopy offers access to all the different electronic and ionic processes
taking place simultaneously in an operating solar cell. To date, its use on perovskite solar …

So-called negative capacitance seems to remain an obscure feature in the analysis of the
frequency-dependent impedance of perovskite solar cells. It belongs to one of the puzzling …

Organic–inorganic lead trihalide perovskites have emerged as an outstanding photovoltaic
material that demonstrated a high 17.9% conversion efficiency of sunlight to electricity in a …

Metal halide perovskite (MHP) devices often show different types of hysteresis in separate
voltage domains. At low voltage, the impedance response is capacitive, and the cell gives …

Characteristic times of perovskite solar cells (PSCs) have been measured by different
techniques: transient photovoltage decay, transient photoluminescence, and impedance …

We report a highly efficient solar cell based on a submicrometer (∼ 0.6 μm) rutile TiO2
nanorod sensitized with CH3NH3PbI3 perovskite nanodots. Rutile nanorods were grown …

Mesoscopic solid-state solar cells based on the inorganic–organic hybrid perovskite
CH3NH3PbI3 in conjunction with the amorphous organic semiconductor spiro-MeOTAD as …
