Pre-requisites before taking this module (or general academic requirements):



The aim of this module is to give students an understanding of:
1. The underlying principles of the chemistry of electrochemical storage devices (batteries, supercapacitors) and energy conversion devices (fuel cells).
2. The fundamentals of solar energy conversion including photovoltaics and artificial solar synthesis.
3. How chemistry impacts strongly on everyday devices - using the "smart phone" as an illustrative example to introduce concepts of modern displays (liquid crystal, organic LED), coating technology and transistors.

Learning Outcomes

(LO1) By the end of this module a student will be able to demonstrate an understanding of:
* simple chemical and electrochemical reactions
* the relationship between fundamental materials properties and technological applications
* the role of chemistry in complex multidisciplinary technologies
* basic principles of battery/supercapacitor electrochemistry - such as the electric double layer
* calculation of theoretical specific energies and energy densities
* challenges and goals of research in energy storage/conversion devices
* intercalation of ions into host structures
* the basic principle of operation of a fuel cell
* basic theory of semiconductors
* different classes of photovoltaic devices
* basic principles of an artificial leaf
* the chemical technologies involved in the realisation of the "smart phone"
* liquid crystalline state and optical anisotropy
* the origin of electrical conductivity

(S1) A student will be able to demonstrate the following skills:
* self-study - via independent reading of suggested review articles

(S2) * critical thinking - for example there are many different energy storage devices with advantageous and disadvantageous properties and scientific challenges to overcome - and the students ability to evaluate material presented to them can be assessed by short essay question in the examination

Teaching and Learning Strategies

This module consists of podcasts providing the material which normally would be presented in 30 lectures which will provide the background material necessary to succeed in this module, incl. the final exam.

The podcasts will be supported by three synchronous tutorials/revision sessions (ideally face-to-face). Each lecturer will set and hold one tutorial/revision session.

These will be followed by quantitative assignments which contribute to the total mark. In these tutorials and assignments students will have the opportunity to apply the knowledge that have gained from the lectures/podcast to problems of varying difficulty.
