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.

Competition

Naturally, some of the competitors have a space heritage, but there are a few entrants from the solar space too.


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.
