Within today’s global challenge to capture and utilize solar energy for a sustainable development on a grand scale, dye sensitized solar cells (DSC), represent a particularly promising approach to the direct conversion of light into electrical energy at low cost and with high efficiency. In these devices, a dye sensitizer absorbs the solar radiation and transfers the photoexcited electron to a...

Recently, polymer or ‘plastic’ solar cells have attracted significant interest due to their potential for cheaper generation of electricity compared with conventional inorganic solar cells.1 This expectation is based on simple device structure and on inexpensive wet-processes such as screen printing, ink-jet printing, spray coating, etc. Other advantages of plastic solar cells are low...

Photovoltaics has the chance of being one of the important players in future energy scenarios. However, current technologies are intrinsically inefficient or quite expensive, and a true technological breakthrough is yet to come - although it might be just around the corner. The state of the art in photovoltaics will be reviewed, describing the fundamental limitations of current technologies...

The world energy consumption is rising, which makes the limitations of fossil fuels more and more apparent. Oil prices are as high as ever. If there is no solution to finding a cost effective and accessible renewable energy source, then the energy problem will become critical soon.
This is certainly one reason that the market of solar cells is one of the fastest growing, despite the fact that...
