The Earth receives an enormous amount of energy from the Sun. Almost 174 petawatts of solar power reaches the upper atmosphere in the form of solar radiation. The sum of non-renewable energy sources could only provide us with half of this power. This is just a measure of the energy potential that we can exploit in order to cover our energy needs and ensure the existence of a cleaner environment and healthier ecosystems. Solar energy is one of the first energy sources discovered, and it is still one of the cleanest and safest.

New Generation of Materials and Techniques
Although photovoltaic cells are widely available in the market today, their application potential is still limited by their low efficiency. The use of semi-conductive materials, mainly silicon, can only yield efficiencies that vary from 18% to 24 % for the normal monocrystalline silicon technology. The latter is considered to be better in terms of performance and cost compared to the multicrystalline silicon technology. These percentages indicate that the current solar technology cannot compete with the conventional use of non-renewable resources, and that's why the solar industry is continually working on the improvement of performance and the lowering of production costs.
The new trend involves the use of organic materials and the development of new techniques suitable for low-cost and large-area production. However, the efficiency achieved so far is in the range of 10-18% approximately, which is significantly lower compared to the efficiency of conventional technology. Despite this fact, research is still in progress and those involved in the field are positive that both the efficiency and performance of photovoltaics will improve over time.
