Solar Commission Report I chaired the Solar Commission whose aim is to show how the UK's extensive innovation and industrial capabilities can be harnessed to enable the UK to play a leadership role in what will undoubtedly be one of the key energy generation technologies of the coming decades. This report was launched at the House of Lords Tues 9 July 2019.University of Bath Research with Impact Podcast with Roland Pease: 'A bright future for solar energy' features interviews by the internationally renowned journalist Roland Pease with Prof Petra Cameron and myself on the future of solar power.
Applying machine learning to perovskite solar cell modelling describes recent advances by my research group on utilising artificial intelligence to understand the new solar technology of perovskite solar cells.

Solar Cells
Solar cells are devices that produce electricity from the sun's energy through the creation and subsequent dissociation of an exciton. The way in which they work is similar to natural photosynthesis.WHAT TYPES ARE THERE?
There are several solar cell technologies and in each, the light-active component and other cell materials are different.
Organic solar cells consist of layers and/or blends of organic materials.
Hybrid solar cell These solar cells consist of a mixture of organic and inorganic materials.

Organic Materials and Devices
Organic Materials and Devices We're all taught at school that plastic is an insulator, but some carbon-based small molecules and polymers do conduct electricity. Unlike silicon-based electronics, organic electronics are relatively low performance but cheap and flexible. And when they conduct, they can light up, click here for my article on lighting based on organic light emitting diodes (OLEDs), be used in displays, or convert light to current in photovoltaics.WHAT DEVICES ARE THERE?
Organic Field Effect Transistors used in smart packaging, brand protection, security, smartcards, distribution tagging and Radio Frequency Identification Devices, interactive media, disposable electronics, and (flexible) display backplanes. Organic devices are being developed that can restore or replace functions of the human body through managing the interface between electronic devices and cells, tissues and organs.
