CPV Market Analyzed and Forecast in Research Report by SNE Research

08 Apr 2013 • by Natalie Aster

The concept of CPV (Concentrated photovoltaics) technology was introduced in 1980s-1990s when the price of crystalline silicon solar cells was too high as an attempt to use cheap optical systems to concentrate the same amount of light into small sized solar cells in order to reduce silicon consumption as much as possible.

Since increasing the concentration ratio enables to relatively reduce costs of space, there was effort to use fewer high efficiency solar cells with excellent photoelectric conversion efficiency and minimize other requisites such as installation costs, installation sites, and BOS (Balance of system). In addition, there has been effort to develop solar cells with excellent durability and long-life to reduce costs for power generation.

According to the report “CPV(Concentrated Photovoltaics) Technology and Market Forecast(2009-2020)” by SNE Research, concentrate photovoltaics mostly use III-V compound semi-conductor solar cells based on GaAs or InGaP, which have an advantage of high optical absorptivity over existing silicon solar cells due to their direct-transition type band gaps. In addition, covalent bonds enable excellent physical properties. GaAs as one of compound semi-conductors has proved to have high reliability despite extreme conditions in the field of semiconductor laser, which deals with more complex structures.

III-V compound semi-conductor solar cells make it possible to fabricate more advanced multi-junction tandem solar cells instead of single junction by monolithically stacking solar cells of different absorption bands. These tandem III-V solar cells are fabricated by epixatially growing materials with different band gaps through MOCVD, and have the potential to develop solar cells with ultra-high efficiency of more than 50%, since it is possible to use most of the solar spectrum through stacking layers.
