I am interested in developing composite materials for use in solar energy hardware by using application of microwave energy.
These are the main materials used in a solar park:
Modules: Solar cells (PV cells) can be made from various types of semiconductor materials. The first type is crystalline form of silicon (c-Si) or amorphous silicon (a-Si). The second type is polycrystalline thin-film semiconductors, including copper indium gallium diselenide (Cu(InGa)Se2 or CIGS), and cadmium telluride (CdTe) and thin film silicon. The third type is single-crystalline thin films including gallium arsenide (GaAs).
Investors: The higher power investors are cheaper, between US$0.13 and US$0.15 cents/Wp. Those of lesser powers to smaller systems can reach about US$0.40 cents/ Wp. The medium-term forecast is that costs will continue to decline below the US$0.10 cents / Wp for higher powers.
Structures: The cost of steel structures for systems that support perpendicular winds of 150 km / hour, will decrease as a result of better designs. Its costs have been above US$0.25 cents/ Wp, but there are designs that can take the cost below US$0.12 cents / Wp. With the increase in the efficiency of the modules will decrease the cost of the structures.
The example being used since 2012 in supporting structures of solar PV systems, consist of:
1. Poles (front and rear buried).
2. Transverse supports (cross members)
3. Modules support (sub-structure).
All with a view to reducing by more than two times the cost of these components, this means over US$0.20 cents/ Wp to less than US$0.12 cents/ Wp for module efficiencies 15% and less than US$0.9 cents/ Wp for efficiencies of 20%, to be achieved by 2020.
Electricity: Includes wiring and other electrical parts of the solar PV system. With the increase in the efficiency of the solar PV modules will decrease the cost of cabling.
