Much as magnifying glasses can concentrate sunlight and burn holes in leaves, concentrators use optics to concentrate sunlight onto a small area of solar cells. These photovoltaic (PV) cells convert the light into electricity—clean, homegrown, and pollution free—that we can use to run our appliances or light our homes.
The concentrator photovoltaics technology is one of the best ways to enhance the yield of conversion efficiency by using the approach of focusing sunlight. Concentrated photovoltaics (CPV) also reduce the area of photovoltaic cell which is one of the main economic advantages of CPV.
The benefits of concentrator photovoltaics and review objectives The sun delivers 120 petajoules of energy per second to the Earth. In 1 h the sun delivers more energy to Earth than humanity consumes over the course of a year. The ability to harvest this solar energy efficiently and cost effectively however is challenging.
Arizona Public service studied that in future high efficiency solar cells will dominate by high concentrator with high efficiency cell . As if researchers reduce these costs then photovoltaics technology would become more feasible, and one of the solution of this problem is PV concentrators .
Trends towards higher performance solar concentrator designs include the use of micro-patterned structures and attention to detailed design such as tailoring secondary optics to primary optics and vice-versa.
Conclusion An extensive review of solar concentrator research and technologies has been carried out, comparing different materials and the optical performance of different designs. There is not enough consideration into the durability of designs and their performance over years of use, especially for concentrators utilising refractive optics.
