How to calculate requirements for efficient solar cells

transparent conductor layerHOT Communicationread it first!

In this work, the authors calcualte how sheet resistance impacts the power conversion efficiency in solar cells.

The transparent conductor (TC) layer in thin film solar cell modules has a significant impact on power conversion efficiency – reflection, absorption, resistive losses and lost active area all need to be taken into account.

Supercapacitors with high volumetric capacitance

HOT Communication – continuous carbide-derived carbon film

CDC filmMonolithic porous carbon film has a great potential for integrated supercapacitors due to no polymer binder, reduced macropore volume, and good adhesion between current collector and active material.

It is demonstrated that continuous carbide-derived carbon (CDC) films can be synthesized on various substrates and show high volumetric capacitance.

Microcube cathode improves solid oxide fuel cells

SOFC‘HOT’ EES paperread it now

This work has demonstrated that the electrocatalytic activity of the solid oxide fuel cell cathode can be improved by tailoring the surface crystal facet of micro-crystals. The knowledge obtained will facilitate the goal to improve energy efficiency and to reduce emissions.

Is Chemistry the Key to Sustainable Living?

Come and see this public lecture!

Tuesday 23 November, 2010, The Chemistry Centre, London
Speaker: Mike Pitts, CiKTN

This lecture will highlight one of the priority areas in the RSC Roadmap: Sustainable Product Design. It will look at how the entire life cycle of products – from design through to disposal – can be assessed to help preserve resources. Mike Pitt’s talk will be stressing the scale of the sustainability challenge, while highlighting how it should be viewed as an opportunity by chemistry-using companies.

Flexible photovoltaics – EES in the New Scientist

An Energy & Environmental Science article on photovoltaics has been featured in the New Scientist.

The article by Brian Korgel and colleagues at The University of Texas at Austin describes a new nanocrystal photovoltaic device which can be sprayed on to a surface – making it very useful for flexible materials such as clothes or beach towels!

Improving hydrogenase O2 tolerance for a sustainable hydrogen economy

HOT Review articleread it now

Improving hydrogenase O2 tolerance is a major contemporary challenge to allow the implementation of a sustainable hydrogen economy, as hydrogenases catalyze the conversion between 2H+ + 2e and H2.

In this Review Christophe Léger and colleagues explore different methods to improve the O2-tolerance of the O2-sensitive [Ni–Fe] hydrogenase.
