8. Organic photovoltaic (OPV) l by Cetemmsa TAFF
Thin film photovoltaic technologies consitute the third generation of solar cells:
 flexibility
 low weight
 low energy-consumming fabrication processes
 low cost
OPV is particularly interesting because of:
 solution process: R2R compatibility
 low toxicity (vs. CdTe or CIGS for example)
 potential to be cheaper than any other technology
