ORGANIC SOLAR CELL COMPRISING AN INTERMEDIATE LAYER WITH ASYMMETRICAL TRANSPORT PROPERTIES

摘要

#CMT# #/CMT# The solar cell has an antireflection layer (2) on the outside of a transparent plastics, glass or crystalline substrate (4). A first layer on the inner side of the substrate is an electrode (8). It may act either as the cathode or the anode and may be made of aluminum, copper or ITO (Indium Tin Oxide). #CMT# : #/CMT# A first intermediate layer (10) has an asymmetrical conductivity and acts as an electron acceptor. It also acts as an optical antireflection layer. The next active layer (12) has an electron acceptor side (14) contacting the first intermediate layer and an electron donor side (16) contacting a second intermediate layer (18) and an electrode layer (20). #CMT#USE : #/CMT# Solar cell for generating electrical current, made of organic material with metal electrodes. #CMT#ADVANTAGE : #/CMT# Material may have high mobility of holes and may have high efficiency. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a diagram of the layer structure of the organic solar cell. 2 : Antireflection layer 4 : Transparent plastics, glass or crystalline substrate 8 : Electrode 10 : First intermediate layer 12 : Active layer 14 : Electron acceptor side 16 : Electron donor side 18 : Second intermediate layer 20 : Electrode layer.
