Fabrication and Characterization of Functional ALD Metal Oxide Thin Films for Solar Applications

Ludmilla Steier

Motivated to revolutionize our today's fossil fuels based energy production, my work concentrated on the investigation of promising low-cost materials for photoelectrochemical hydrogen production and photovoltaic electricity generation. Hydrogen presents a ...

Energy Challenges in the Global South

Silvia Hostettler

Energy needs at the global level are gigantic and steadily increasing while the need to reduce carbon emissions is vital if catastrophic climate change is to be avoided. In the Global South, a large part of the population still lacks access to energy, whic ...

Pervasive Data Analytics for Sustainable Energy Systems

Tri Kurniawan Wijaya

With an ever growing population, global energy demand is predicted to keep increasing. Furthermore, the integration of renewable energy sources into the electricity grid (to reduce carbon emission and humanity's dependency on fossil fuels), complicates eff ...

Given the intermittent nature of solar radiation, the large-scale use of solar energy requires an efficient energy storage solution. So far, the only practical way to store such large amounts of energy is in the form of a chemical energy carrier, i.e., a f ...

Royal Soc Chemistry2014

Providing energy for a population projected to reach 9 billion people within the middle of this century is one of the most pressing societal issues. Burning fossil fuels at a rate and scale that satisfy our near-term demand will irreversibly damage the liv ...

Analysing and modelling the growth and efficiency of urban transportation infrastructures

Jean-Louis Scartezzini, Nahid Mohajeri Pour Rayeni

The total population of the United Kingdom is expected to increase from 63 million in 2011 to 73 million people in 2037. This is an increase by 16% in 26 years, which puts the urban infrastructure, particularly the transportation infrastructure, under grea ...

Net primary energy balance of a solar-driven photoelectrochemical water-splitting device

Sophia Haussener

A fundamental requirement for a renewable energy generation technology is that it should produce more energy during its lifetime than is required to manufacture it. In this study we evaluate the primary energy requirements of a prospective renewable energy ...

Interfacial Self-Assembly as Catalytic Platform for Multielectron Redox Reactions

Astrid Johana Olaya Avendano

In Nature, many vital biological processes take place across the interface formed between two dielectric media. For instance, photosynthesis and aerobic respiration involve a series of redox reactions occurring across energy-transducing membranes, in charg ...

Cu-based p-type Oxide Photocathodes for Solar Hydrogen Production

Adriana Paracchino

The actualization of a hydrogen economy requires cost-effective and environmentally benign solutions to hydrogen production. Chemical energy in the form of hydrogen is more interesting than electricity to satisfy our ever-increasing energy demand because i ...
