Thin-layer solar cells may bring cheaper solar energy to consumers.
Scientists at Durham University are working on development of light absorbing materials for use inside thin-layer solar photovoltaic cells which convert light energy into electricity.
The four year experiments tested a range of materials that could lead to cheaper manufacturing of solar panels. Thicker silicon cells, commonly used today, are much more expensive because they use more rare metal in the power conversion.
The research, funded by private organizations, focuses on development of thin layer cells that use copper indium diselenide and cadmium telluride which are much cheaper than todays solar panels.
The university hopes that development of more affordable solar cells could lead to cheaper solar panels for the domestic market, spurring the increase of solar power usage through the UK. Solar power currently provides less than a percentage point of power throughout the UK.
Professor Ken Durose, Direct of the renewable energy department in Durham Centre, says that 'One of the main issues in solar energy is the cost of materials and we recognize the expensive cost is slowing down the uptake of solar cells in the UK'
He also said that, 'If we can make solar panels more cheaply through our material research, then we will have a winning product.'
