“…The front surface of the Si wafer is coated with a phosphorous spin-on-dopant (SOD) 22 for an n-type emitter by spin coating and 2 mm-thick Al is deposited on the back surface for a P + back surface field (BSF) by e-beam evaporation, which is co-fired using rapid-thermal annealing at 950 1C for 1 min. 23,24 The emitter surface is then passivated by an 80 nm-thick SiN x thin film deposited by plasma enhanced chemical vapor deposition (PECVD). 25 Fig.…”

A B S T R A C TA dodecapeptide (AMRKLPDAPGMH) functionalized with a tetramethylrhodamine (TAMRA) chromophore at the N-terminus was immobilized on nanocrystalline TiO 2 . The optical and binding properties of the peptide layer immobilized on the titania surface were characterized by UV-vis absorption, steadystate fluorescence and X-ray photoelectron spectroscopies. Circular Dichroism experiments and Molecular Mechanics calculations showed that the predominant conformation populated by the peptide scaffold brings Arg3, Lys4 and Asp7 in the correct position for linking the TiO 2 surface. Photocurrent generation experiments were therefore carried out to determine the photon-to-current conversion efficiency (IPCE) of a Grätzel-like Dye Sensitized Solar Cell (DSSC), the photoactive unit of which is formed by TAMRA-AMRKLPDAPGMH/TiO 2 . The measured IPCE amounted to 0.65%, a value that is definitely low, but superior to those previously reported for similar bioinspired DSSCs. This result can be ascribed to the light-harvesting properties of the TAMRA chromophore and to the unique structural properties of the peptide spacer.
