The understanding of the electronic properties of nanostructures is one of the most rapidly advancing areas in science. This has two major implications first, it will lead to the construction of nanocircuitiy and nanocomputers that will use considerably less power than current computers while being faster and smaller and second, it will lead to increasing efficiency and decreasing cost of photovoltaic power conversion ( solar energy ).

The recent experimental developments on dark and photoinduced ET reactions give support to the previous speculations on the relevance of these interfaces in such fields as catalysis and solar energy conversion. These disciplines have been, and still are centered on processes at solid solution interfaces. However, particular applications require molecu-larly defined interfaces, where reactants exhibit different solubility properties. In this section, we shall consider some of these systems and the advances reported so far.

Within the solar system the observable changes are of a different kind, best described as chemical change. The most striking common feature of those chemical reactions driven by solar energy is their cyclic nature, linked to planetary motion. All phenomena, collectively known as life, or growth, are of this type. Their essential characteristic is a state far from equilibrium. For a life process, equilibrium is synonymous with death and chemical change after death is a rapid slide towards equilibrium. The most advanced chemical theories deal with these posthumous effects and related reactions only, albeit rather superficially. A fundamental theory to predict conditions for the onset of elementary chemical change is not available.

A comparison is made of the available resources, their principle economic ex-ploitability and actual prognosis for their use. Again one notes the enormous potential of solar energy. Rapid growth is foreseen for biomass, solar and wind. A difference is made between traditional and modern use of biomass, because currently, especially in less developed countries, biomass is also an important energy source, but is not used in a technologically advanced way. 

Scientific interest in nanocarbon hybrid materials to enhance the properties of photocatalysts and photoactive electrodes has been growing rapidly [1-8]. The worldwide effort to find new efficient and sustainable solutions to use renewable energy sources has pushed the need to develop new and/or improved materials able to capture and convert solar energy, for example in advanced dye-sensitized solar cells - DSSC (where the need to improve the photovoltaic performance has caused interest in using nanocarbons for a better cell design [9,10]) or in advanced cells for producing solar fuels [11-13]. 

If solar energy were to supply the energy needs of the world s population, it would require large areas to be dedicated to it. These could be in sunny areas of low population such as deserts, or the oceans. It should be remembered that salt water is no barrier to the growth of many of these organisms. However, technological advances on this scale are obviously long term.

Thus, it appears that several systems have been developed which hold promise as prototypes of biomimetic solar energy conversion devices. And in conjunction with the advances being made in experimental and theoretical methods for investigating molecular excited-state processes, prospects for the development of practical biomimetic devices are now substantially better than they were only a decade ago. 

Whilst these approaches are extremely interesting scienhfically, to be of any real commercial value in solar energy utilisation the stability of the systems must advance by orders of magnitude.

In summary, we have described the main concepts of two components of our program, one on composite materials and the other on alloys. The experiments on composite materials are still not advanced enough to tell how effective such materials will be as electrodes. The results on the alloys show some promise, and point to the need for a more basic materials approach in order to obtain improved electrodes.
