Potassium-chemical synthesis of 3D graphene from CO2 and its excellent performance in HTM-free perovskite solar cells [PDF]
The conversion of greenhouse gas CO2 into novel materials is the most promising approach to solve greenhouse gas issues. Herein, we report for the first time the reaction of potassium with CO2 to synthesize three-dimensional honeycomb-like structured ...

On Mott-Schottky analysis interpretation of capacitance measurements in organometal perovskite solar cells [PDF]
Capacitance response of perovskite-based solar cells (PSCs) can be exploited to infer underlying physical mechanisms, both in the materials bulk and at outer interfaces. Particularly interesting is applying the depletion layer capacitance theory to PSCs,

Mott-Schottky Analysis of Laboratory Prepared Ag2S-AgI Membrane Electrode
Mott-Schottky analysis has been carried out to study the semiconducting behavior of Ag2S-AgI material, which is used as membrane material in iodide ion sensors. Polycrystalline Ag2S-AgI materials with mixing ratios 1:1wasprepared by co-precipitation method and Mott-Schottky analysis was carried out.

Modified Mott-Schottky Analysis of Nanocrystal Solar Cells
Mott-Schottky analysis is adapted to determine the built-in bias (Vbi) and doping density (N) of lead sulfide-zinc oxide colloidal quantum dot heterojunction solar cells. We show that charge injection barriers at the solar cell's electrodes create a constant capacitance that distorts the junction's depletion capacitance and result in erroneous Vbi and ...

Mott-Schottky analysis of archaeological copper-based objects
The application of Mott–Schottky (M−S) analysis of impedance data to sub–micro samples extracted from the corrosion patina of copper, bronze, and brass archaeological artifacts attached to graphite electrodes is described. The corresponding theoretical approach is developed to account for the contribution of the composition and structure of the ...
