Porphyrinoids are employed as components of photovoltaic and artificial photosynthetic devices[1-3].However,synthetic porphyrin analogues such as phthalocyanines[4] have the advantage,as photon harvesters,of exhibiting very high extinction coefficients in a wavelength range that extends to around 700 nm,where the maximum of the solar photon flux occurs.Consequently,Pcs have emerged as excellent light harvesting antennas for incorporation into donor-acceptor systems,mainly in connection with fullerenes as an acceptor moiety or just as sensitizers in DSSC (Figure 1),for example.During this talk an overview of the results obtained by our group in Madrid during the last few years will be given.[5-8]
