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
