The solar to electric power conversion efficiency of dye-sensitized solar cells of laboratory scale (0.158 cm2), validated by an accredited photovoltaic calibration laboratory, has reached 11.1% under standard reporting conditions, i.e., air mass 1.5 global sunlight at 1000 Wm-2 intensity and 298 K temperature, rendering it a credible alternative to conventional p-n junction photovoltaic devices [68]. Photovoltaic performance data obtained with a sandwich cell under illumination by simulated AM 1.5 solar light using complex 26 are shown in Fig. 16. At 1 sun the 26-sensitized solar cell exhibited 17.73 =b 0.5 mA current, 846 mV potential, and a fill factor of 0.75 yielding an overall conversion efficiency of 11.18%. 

Solar cells devices based on CuPc and C6o fullerene have reached power conversion efficiencies of up to 5% [266,271], the highest efficiency for a Pc-containing solar cell being represented by a tandem cell in which two cells, each of them composed of a mixed donor/acceptor CuPc/C6o layer sandwiched between homogeneous donor and acceptor layers, are coupled (efficiency = 5.7%) [272],... 

Organic solar cells have reached efficiencies exceeding 4%. In fact power conversion efficiencies of organic solar cells have reached an impressive 5%. This has been possible because of the discovery of bulk heterojunction solar cells. Solar cells are discussed in Chapter 5. 

Physical incorporatiem of phthalocyanines and porphyrins in polymers was mentioned in Chap. 2.1.1 and 2.1.2. Moreover, photovoltaic properties of Schottky bavier solar cells were checked by dispersing metal free Pc in a polymer binder At peak solar power (135 mW/cm ) a power conversion efficiency of 1,2% has been obtained.

Hanna and Nozik (2006) have used the detailed balance model to calculate the power conversion efficiency of single-gap and two-gap tandem solar conversion devices which employ QD absorbers capable of MEG after photon absorption. The detailed balance model has been used previously (Shockley and Queisser, 1961 Werner et al, 1994 Spirkl and Ries, 1995 Brendel et al, 1996 Wiirfel, 1997 de Vos and Desoete, 1998 Landsberg and Badescu, 2002) to calculate the limiting efficiency of ideal solar...
