FLEXO Magazine : June 2008
ics reel-to-reel in Germany and the u.s. this year and it promised "unprecedent- ed cost efficiency and scale ability" and "near 100-percent materials utilization" using nano-particle dispersions depos- ited at high speed on low-cost metal foil. Work printing dye sensitized solar cells (DSSC) in the UK by an ink-jet like pro- cess was mentioned. Another presenter described an acoustically constrained aerosol spraying method for photovolta- ics that can even pattern on edges. Other speakers referenced an ambitious new organic PV venture supported by BASF and Robert Bosch, which will bring reel- to-reel vacuum deposition of organic PV to the market with high-performance organics containing C60 buckyballs in pin tandem cells. J oint ventures in Japan and Germany, with research in Austria and the U.S., were described in a speech called, ttprinted Photovoltaics on the Way Toward Commercialization." A French firm described its breakthroughs in research in this area, notably thin film devices with organic electronics as a complementary technology. Several organizations now demon- strate around S-percent efficiency with organic PV, near where applications that prioritize cost over footprint can kick in. Spectral efficiency can be better than sili- con. Indeed, some projected continuing O.S-percent annual improvement in best recorded organic efficiency and others' objective is to overcome the "one Euro per peak watt barrier" with 7 to 10 per- cent efficiency and very low costs. A representative of DuPont spoke about photovoltaic inks. A speaker from The University of Augsberg talked about challenges of material scarcity in some cases and analysts IDTechEx projected the markets for the next 20 years. There was also a Masterclass on "Photovoltaics: New Markets." Clearly things are on the move.
