Hi, Dye sensitised solar cells appeared on the solar community around the beginning of the 90's when some companies (start-ups and not) bought a license from EPFL to commercialise the technology. Since then, several companies (larger and very small) tried to put this technology into the market without success (only small quantities were "sold" for special projects, mainly research or demonstration ones) because of several technological reasons. Recently, some examples of such technology can be found installed around the most important one is the one installed at the swiss tech convention center at the EPFL campus (!!) (see for example, https://en.wikipedia.org/wiki/SwissTech_Convention_Center). So, no market share in the PV business yet despite more than 20 years trials....
If you want to know about the world-wide commercial status of PV, have a look at the "Photovoltaics Report" published by Fraunhofer ISE (https://www.ise.fraunhofer.de/en/publications/studies/photovoltaics-report.html -- formerly https://www.ise.fraunhofer.de/en/renewable-energy-data/data-and-facts-about-pv). The data given in the relevant PDF file are updated every few months; it's worthwhile to have a look at all its 43 pages.
From this report you can see that presently, with regard to thin-film PV, only CdTe and CIGS technologies are commercially relevant; a-Si is quickly loosing market shares (and will soon die out because of too low efficiency, I guess). Further relevant arguments about the present and future market situation can be found here: https://www.researchgate.net/post/Do_silicon_solar_cells_have_their_monopoly_in_the_market_for_a_long_period
The initial hope of DSSC was that the technology would be substantially cheaper to make than silicon. The very large drop in silicon prices has removed this hypothetical advantage. DSSC is now morphing into perovskite type cells. Maybe these will 'take off'.
Just in case you want to know about the companies working on commercialization of this technology, check the website of below
G24Innovation (UK)
Dyesol (Australia)
Solaronix (Switzerland)
3gsolar (Jerusalem, ISRAEL)
I believe this technology is still very active in research and have lot more potential than perovskites because of less environment risks and ease of making, with particularly in solar fuels related to photo-electro-chemical cells.
Dyesol as far as I know (check their website) is the most ready to use it's technology to support other end use manufacturers. However it is also pursuing perovskite cells - which presently contain lead and are therefore not ideal from environmental reasons. Dyesol will sell all the chemicals, test gear etc for you to make your own cells.
Hey, what was wrong with my answer from Apr 24, 2016? Why did I get a downvote for just pointing to facts? If somebody thinks I missed something relevant, please tell!
Of course, Today's silicon-dominated photovoltaics market is abuzz with high statistics and according to market projections by IDTechEx, the market for dye sensitized solar cells (DSSCs) will slowly grow to over $130 million by 2023.
