Original Kurzfassung:
Semitransparent inverted organic photodiodes are fabricated with a
Baytron PH500 ethylene-glycol layer/silver grid as the top electrode.
Reasonable performances are obtained under both rear- and front-side
illumination and efficiencies up to 2\% are achieved. Some light is
shed on visual prospects through optical simulations for a
semitransparent device of poly(3-hexylthiophene) (P3HT) and the C70
derivative 1-(3-methoxycarbonyl)propyl-1-phenyl[6,6]C-71 (PC70BM) in
the inverted structure. These calculations allow the maximum efficiency
achievable to be predicted for semitransparent cells based on
P3HT:PC70BM versus the transparency perception for a human eye. The
simulations suggest that low-bandgap materials such as
poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopenta[2,1-b;3,4-b']dithioph
ene)-alt-4,7-(2,1,3-benzothiadiazole)] (PCPDTBT) have a better
potential for semitransparent devices. In addition, the color range
recognized by the human eye is predicted by the optical simulation for
some semitransparent devices including different active layers.
