Value Chain Activity: Manufacturing high-efficiency multi-junction Cells

Similar to thin-film manufacturing, thin layers of photovoltaic material are deposited onto a substrate. The emphasis here, however, is on quality, rather than cost. This way, cell efficiencies of over 40% are achieved.

Industry Context


Conclusion

With increasing interest from terrestrial photovoltaic module makers, there will be more entrants into this market, which will put pressure on cost and margins.

Competition

The industry is dominated by three companies covering 95% of the market. They all come from the space- business, but are now extending into terrestrial applications. However, the market has seen a number of new entrants to crash the established oligopoly.


PV Cell
 

Substitutes

With efficiencies of crystalline silicon products increasing, it could become a serious contender. However, in some segments, high efficiency can not be replaced by cheaper products.

 

Downstream

In the terrestrial solar market, buyers are concentrating pv module makers.
