Sean Nuzum and Tim Davey, who both studied for the MEng in Electronic Engineering at the University's School of Electronics and Computer Science (ECS), based their final year projects on solar energy. Their work was supervised by Professor Darren Bagnall at ECS.
In a research project entitled Solar technology: emerging markets and global economic forecasting, when should you go solar?, Sean predicts that due to the rate at which gas and electricity prices are soaring, and the rate at which photovoltaics is decreasing, it will be cheaper to use solar cells by 2014.
In order to make these cells more efficient than electricity, Tim proposes using devices based on amorphous silicon and develops a case for this in his research project entitled High efficiency a-Si thin-film multi-junction solar cells for the commercial market,
Silicon is plentiful and much less toxic than other materials used to make thin film solar cells and can be deposited as thin film and can be stacked in such a way as to trap light, which increases the cells efficiency and could result in a cell which is 12 percent efficient.’
Both researchers believe that it is time for consumers to think seriously about installing solar panels.
Sean believes that the most common argument against using them is the initial capital outlay needed.
He said: 'The average system today in 2008 costs approximately £3,000 including grants, with a payback time of just six years and this period will reduce significantly over the coming decade.
'The future is certainly bright for the photovoltaics industry and the time is right to go solar.'

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
