One of the most fascinating characteristics of perovskite solar cells (PSCs) is the retrieved obtainment of outstanding photovoltaic (PV) performances withstanding important device configuration variations. Here we have ...
Trend of Perovskite Solar Cells: Dig Deeper to Build Higher
(American Chemical Society, 2015-06)
Using solar energy efficiently to produce electricity has been the subject of intensive research because of the rapid increase of global energy demand and the need to reduce the emission of greenhouse gases from electricity ...
Polarization Switching and Light-Enhanced Piezoelectricity in Lead Halide Perovskites
(American Chemical Society, 2015-03)
We investigate the ferroelectric properties of photovoltaic methylammonium lead halide CH3NH3PbI3 perovskite using piezoelectric force microscopy (PFM) and macroscopic polarization methods. The electric polarization is ...
Science in the Age of Digital Networking
(American Chemical Society, 2015-08)
Today, the world is moving fast, but we do not know
exactly where this leads yet. As the economy of knowledge
inevitably extends its tentacles on the realm of science, what are
we –scientists- going to do? So far, an ...
Boosting Power Conversion Efficiencies of Quantum-Dot-Sensitized Solar Cells Beyond 8% by Recombination Control
(American Chemical Society, 2015)
At present, quantum-dot-sensitized solar cells (QDSCs) still exhibit moderate power conversion efficiency (with record efficiency of 6–7%), limited primarily by charge recombination. Therefore, suppressing recombination ...
Analysis of bio-anode performance through electrochemical impedance spectroscopy
(Elsevier, 2015-12)
In this paper we studied the performance of bioanodes under different experimental conditions using polarization curves and impedance spectroscopy. We have identified that the large capacitances of up to 1 mF·cm− 2 for ...
Diamond-based electrodes for organic photovoltaic devices
(Elsevier, 2015-03)
The present paper demonstrates the possibility of replacing indium–tin oxide (ITO) with heavily boron-doped diamond (BDD). Plasma Enhanced Chemically Vapor Deposited BDDs layers of various thicknesses were prepared containing ...
