6 FAQs about [Concentrator cell substrate materials]

What is a concentrator solar cell?

The solar cells which are the most expensive parts of PV system were replaced by much cheaper optical elements when using concentration technology, thus the costs could be decreased further, and the concentrator solar cell was considered to be one of the third generation solar cells .

How to reduce series resistance of concentrator silicon solar cells?

Thus, the series resistance of the concentrator silicon solar cell must be made lower than that of common silicon solar cells to decrease the power losses under concentration to keep the high efficiency, and the series resistance could be decreased by changing the structure of the cell. 4. Concentrator silicon solar cells with different structures

How efficient are silicon concentrator solar cells for mass production?

Slade, A, Garboushian, V. 27.6% efficient silicon concentrator solar cells for mass production. In: Proceedings of the Technical Digest, 15th international photovoltaic science and engineering conference. Beijing; 2005. Slade, A, Stone, KW, Gordon, R, Garboushian, V. High efficiency solar cells for concentrator systems: silicon or multi-junction?

Can a concentrator be used in a solar array?

The concentrator approach is the only way for the large-scale use of high-efficiency III–V SCs for terrestrial applications. Indeed, optical elements made of relatively cheap materials can focus the sunlight on small-in-area cells, which allows reducing drastically the consumption of semiconductor materials in production of solar arrays.

Why do solar cells need a smaller concentrator?

Miniaturizing the concentrator and the solar cell offers the advantages of less absorption loss owing to the thinner concentrator, better heat dissipation from the solar cells, and a thinner module thickness, i.e., a lighter module weight, owing to the shorter focal length 42, 43.

What are the different types of silicon solar cells used for concentration?

Six kinds of silicon solar cells used for concentration will be discussed below: front and back contact cell, back contact cell, vertical junction cell, micro cell, silicon based hetero-junction cell and silicon based multi-junction cell.
