(© 2011 American Institute of Physics, 2011-04)
In this study, full coincidence between impedance spectroscopy and transient photovoltage techniques in measuring recombination kinetics of photogenerated charge carriers in inverted polymer:fullerene organic solar cells ...
Assessing possibilities and limits for solar cells
(Wiley, 2011-05-05)
What are the solar cell efficiencies that we can strive towards? We show here that several simple criteria, based on cell and module performance data, serve to evaluate and compare all types of today's solar cells. Analyzing ...
State-of-the-art and limitations in the life cycle assessment of ionic liquids
(Elsevier, 2019-01-19)
Even though the development and use of ionic liquids (ILs) has rapidly grown in recent years, in the literature, information addressing the environmental performance of these substances in a life cycle context is comparatively ...
Environmental performance of 3D-Printing polymerisable ionic liquids
(Elsevier, 2018-12-28)
This work presents a “cradle-to-gate” Life Cycle Assessment (LCA) of 3D-printing polymerisable ionic liquids (PILs) using digital light projection (DLP). It is based on primary data from environmental emissions, wastewater, ...
Investigation of pressure drop in 3D replicated open-cell foams: Coupling CFD with experimental data on additively manufactured foams
(Elsevier, 2019-12-01)
Open-cell foams as structured catalyst supports are promising candidates for the design of high throughput catalytic processes. In this contribution, we employ a coupled numerical and experimental approach to assess the ...

the continuous development of biomedicine, catalysis, and energy applications. In this contribution, a ...
Analysis of the Hysteresis Behavior of Perovskite Solar Cells with Interfacial Fullerene Self-Assembled Monolayers
(American Chemical Society, 2016-10)
The use of self-assembled monolayers (SAMs) of fullerene derivatives reduces the hysteresis of perovskite solar cells (PSCs). We have investigated three different fullerene derivatives observing a decrease on hysteresis ...
Toward Efficient Carbon Nitride Photoelectrochemical Cells: Understanding Charge Transfer Processes
(Wiley, 2016-06)
Hole extraction is the key! Charge recombination, electron injection and hole extraction rates between C3N4, TiO2, and several electrolytes in a photoelectrode configuration are studied. It is found that the TiO2/C3N4 ...
Physical aspects of ferroelectric semiconductors for photovoltaic solar energy conversion
(Elsevier, 2016-10)
Solar energy conversion using semiconductors to fabricate photovoltaic devices relies on efficient light absorption, charge separation of electron–hole pair carriers or excitons, and fast transport and charge extraction ...
