Title:
ORGANIC PHOTOVOLTAIC DEVICES
Document Type and Number:
Japanese Patent JP2009188409
Kind Code:
A
Abstract:
To provide an organic-based photosensitive optoelectronic device with markedly improved efficiency.
The organic-based photosensitive optoelectronic device is, for example, an optimized organic solar cell comprising multiple stacked subcells in series. Each subcell uses a copper phthalocyanine (CuPc) as a donar and perylenetetracarboxylic-bis-benzimidazole (PTCBI) as an acceptor. Ag is used as a thin layer between the front and back cells. Moreover, high power conversion efficiency is realized, by fabrication of a photovoltaic cell comprising multiple stacked subcells with thickness optimization and employing an electron blocking layer.
