Electrical behaviour of thermally diffused silicon solar cells submitted to rapid annealing

Gum Arabica, an Electro-Active Bio-Polymer (EABP) is employed to develop photosensitive bio-complexes with chromophore matter collected from natural flowers and chlorophyll from plant leaves. The photosensitivity and enhancement of electro-activity of the developed complex and nano-cluster doped specimens of the same are examined experimentally. The electrical, optical, and photoelectrical characteristics are also investigated experimentally. It has been observed that the electrical property is mostly mixed conducting and can be tailored. The photo electrical behaviour is found to be fascinating. The developed complex is capable of absorbing light by losing or gaining electrons. The application potential of the developed complex toward light harvesting processes is exploited to develop a non-silicon based solar cell. The electrical characteristics of the developed solar cells are studied. The results obtained are good when compared to those of existing solar cells.

AbstractWe have observed a significant light-induced increase in the open-circuit voltage (Voc) of mixed-phase hydrogenated silicon solar cells. In this study, we investigate the kinetics of the light-induced effects. The results show that the cells with different initial Voc have different kinetic behavior. For the cells with a low initial Voc (less than 0.8 V), the increase in Voc is slow and does not saturate for light-soaking time of up to 16 hours. For the cells with medium initial Voc (0.8 ∼ 0.95 V), the Voc increases rapidly and then saturates. Cells with high initial Voc (0.95 ∼ 0.98 V) show an initial increase in Voc, followed bya Voc decrease. All light-soaked cells exhibit a degradation in fill factor. The temperature dependence of the kinetics shows that light soaking at high temperatures causes Voc increase to saturate faster than at low temperatures. The observed results can be explained by our recently proposed two-diode equivalent-circuit model for mixed-phase solar cells.
