What is a Concentrating Photovoltaic (CPV) system?

Concentrating photovoltaic (CPV) systems are a key step in expanding the use of solar energy.

How does concentrated photovoltaic work?

It was discussed that concentrated photovoltaic uses optical devices, mirrors, or lenses along with tracking system to focus sunlight into a small area of PV cell. Due to the high intensity of sunlight, the temperature of the system increases more and more, resulting the reduction of system overall efficiency.

Can concentrated photovoltaics improve system efficiency?

Tien et al. proposed a novel design of concentrated photovoltaics system which improved system efficiency by capturing more diffused and uniformly distributing solar radiations. In conservative CPV systems, only one optical device was used to concentrate solar radiations on the small area of cell.

What is concentrator photovoltaics technology?

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.

How can micro-concentrator CPV be used for thin-film solar cells?

On the right, a micro-concentrator system with N2 miniaturized solar cells and respective increase (arrow up) or decrease (arrow down) of relevant characteristic parameters. On the other hand, downscaling CPV to the micro-scale also opens new routes for thin-film solar cells.

Could concentrator photovoltaics be a solution to solar power problems?

Concentrator photovoltaics (CPV) could be a solution to this drawback. In CPVs, inexpensive concentrator optics collect sunlight into small-area solar cells so that high power generation can be obtained with relatively low solar-cell usage 33.
