Electrical characteristics of chlorophyll‐a polyvinyl alcohol photovoltaic cells

Electrical characteristics of chlorophyll‐a polyvinyl alcohol photovoltaic cells A type of photovoltaic cell was made by sandwiching micro‐crystalline chlorophyll‐a (chla) layer and polyvinyl alcohol (PVA) film between two semiconductive optical transparent SnO2 electrodes, such as SnO2/chla/PVA/SnO2. The cell showed a dark rectifying effect and presented photovoltaic properties on illumination, which was illustrated by the charge distribution in the cell. It was suggested mat the SnO2/chla junction might be responsible for photovoltage and the chla/ PVA for the charge separation upon irradiation of visible light. The equivalent electric circuit was discussed and its equivalent component values were calculated. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Chinese Journal of Chemistry Wiley

Abstract

A type of photovoltaic cell was made by sandwiching micro‐crystalline chlorophyll‐a (chla) layer and polyvinyl alcohol (PVA) film between two semiconductive optical transparent SnO2 electrodes, such as SnO2/chla/PVA/SnO2. The cell showed a dark rectifying effect and presented photovoltaic properties on illumination, which was illustrated by the charge distribution in the cell. It was suggested mat the SnO2/chla junction might be responsible for photovoltage and the chla/ PVA for the charge separation upon irradiation of visible light. The equivalent electric circuit was discussed and its equivalent component values were calculated.
