Theoretical Analysis of Experimental Data of Sodium Diffusion in Oxidized Molybdenum Thin Films

open access: yesEnergies, 2021
In this work, the diffusion process of sodium (Na) in molybdenum (Mo) thin films while it was deposited on soda lime glass (SLG) was studied. A small amount of oxygen was present in the chamber while the direct-current (DC) magnetron sputtering was used ...

Life Cycle Global Warming Impact of Long-Distance Liquid Hydrogen Transport from Africa to Germany

open access: yesHydrogen, 2023
The global interest in hydrogen as an energy carrier is steadily increasing. In this study, multiple scenarios of liquid hydrogen exports from Africa to Germany are analyzed by life cycle assessment (LCA) to quantify the global warming potential (GWP) of

Understanding the impact of surface roughness: changing from FTO to ITO to PEN/ITO for flexible perovskite solar cells

open access: yesScientific Reports, 2023
So far, single-junction flexible PSCs have been lacking in efficiency compared to rigid PSCs. Recently, > 23% have been reported. We therefore focus on understanding the differences between rigid and flexible substrates.

Efficient photosynthesis of carbon monoxide from CO2 using perovskite photovoltaics [PDF]

open access: yes, 2015
Artificial photosynthesis, mimicking nature in its efforts to store solar energy, has received considerable attention from the research community. Most of these attempts target the production of H2 as a fuel and our group recently demonstrated solar-to ...

PHOTOVOLTAIC MATERIALS [PDF]

open access: yes, 2012
The goal of the current project was to help make the US solar industry a world leader in the manufacture of thin film photovoltaics. The overall approach was to leverage ORNL’s unique characterization and processing technologies to gain a better understanding of the fundamental challenges for solar cell processing and apply that knowledge to targeted

Artificial Feature Extraction for Estimating State-of-Temperature in Lithium-Ion-Cells Using Various Long Short-Term Memory Architectures

open access: yesBatteries, 2022
The temperature in each cell of a battery system should be monitored to correctly track aging behavior and ensure safety requirements. To eliminate the need for additional hardware components, a software based prediction model is needed to track the ...

Transient Optical Characterisation of Donor-Acceptor Block Copolymers for Use in Solar Cells [PDF]

open access: yes, 2010
This thesis presents a study of photo-active, semiconducting block copolymers for use in molecular solar cells. Current state-of-the-art organic devices utilise blends of two (or more) materials that are co-deposited from a common solution; the resulting

Importance of methylammonium iodide partial pressure and evaporation onset for the growth of co-evaporated methylammonium lead iodide absorbers

open access: yesScientific Reports, 2021
Vacuum-based co-evaporation promises to bring perovskite solar cells to larger scales, but details of the film formation from the physical vapor phase are still underexplored. In this work, we investigate the growth of methylammonium lead iodide (MAPbI $$

Improved efficiency of microcrystalline silicon thin film solar cells with wide band-gap CdS buffer layer [PDF]

open access: yes, 2017
In this paper, we have reported a new structure based upon an optical simulation of maximum light trapping and management in microcrystalline silicon thin film solar cells by using multi texture schemes and introducing an n-type cadmium sulphide (CdS ...
