AbstractAt the University of Toledo (UT), we have investigated hydrogenated amorphous silicon (a-Si:H) n-i-p solar cells with intrinsic layers deposited at high rates, ~ 8 Å/s, using our UT multi-chamber load-locked PECVD system. a-Si:H i-layers were grown with a VHF plasma density of ~ 0.2 W/cm2 and a frequency of 70 MHz using various hydrogen dilution levels. It is observed from the current-voltage (I-V) device performance characteristics that the open-circuit voltage (Voc) increases with increasing hydrogen dilution reaching a maximum and then decreasing. This drop in Voc can be attributed to the transition region (or protocrystalline regime) from an amorphous phase into a mixed amorphous+nanocrystalline (a + nc) phase for the i-layer. An initial efficiency of 9.99% (Voc = 0.986 V, Jsc = 13.98 mA/cm2, FF = 72.5%) was obtained. Quantum efficiency (QE) measurement has shown that the blue light response increases as the hydrogen dilution increases. Very good blue light spectral response with QE values over 0.7 at the wavelength of 400 nm have been obtained for a-Si:H cells made under specific deposition conditions in which tailored protocrystalline silicon materials were incorporated at the i/p interface region.

New azomethine-Zn(II) complexes of bis(salicylidene)phenyl-1,2-diamino organic ligand derivatives were synthesized by the reaction of salicylaldehyde, substituted phenyl-1,2-diamine with zinc acetate. The synthesized complexes were characterized by FTIR, 1H NMR and EDS. Their photophysical and electrochemical properties were studied and their applicability for dye-sensitized solar cells (DSSCs) and forensic finger print developments have been demonstrated. Photoluminescence studies revealed that the emission peaks of the complexes in solution state appeared at 372-406 nm and emitted blue light. Latent fingerprint detection study indicated that the powder compounds show good adhesion and finger ridge details without back ground staining. Based on these results, it was ascertained that these Zn(II) complexes can serve as a suitable non-dopant blue light emitting compound for flat panel display applications and applied to detect fingerprints on all types of smooth surfaces.

ABSTRACTWe have degraded a-Si:H p-i-n solar cells at Voc using both red and blue light to investigate the effect of a possible different spatial distribution of defects in the intrinsic layer. We have found that the I-V and the spectral response curves of the degraded cells depend on the total density of defects only and are not sensitive to the wavelength of the degradation light. These experimental results and some peculiar features of the spectral response of the degraded cells are explained with the aid of a numerical simulation program.
