The Photo-Electrical Behavior of n-Si and p-Si/Orange Dye/ Conductive Glass Cells

Abstract

The photo-electrical behavior of n-Si/orange dye/conductive glass and p-Si/orange dye/conductive glass sandwich type cells were investigated. In these cells crystal silicon of n-type and p-type and conductive glass (CG) electrodes were employed and the aqueous solution of organic dye (OD) was used as an electrolyte in the distilled water. Under filament lamp illumination, photo-induced open-circuit voltage and shortcircuit current exponentially dropped with time for the n-Si/orange dye/CG cell. In the p-Si/orange dye/CG cell, the photovoltaic effect was not observed. The n-Si/OD/CG cell showed high photo-electrical response under illumination. In the light-voltage/current conversion, these cells behaved as a differentiator and exhibited charge-storage properties.

Space Charge–Limited Current Model for Polymers

“…Despite all of these successes, the complete picture of charge-transport mechanism, which is highly crucial for further achievements, is still not clear [31][32][33][34][35][36][37][38][39][40]. Due to such ambiguity, different charge transport models are reported to validate the experimental results performed on various polymer devices [41][42][43][44][45][46][47][48][49][50][51][52][53][54].…”
