Abstract

An intermediate layer (110) useful for coupling two individual organic photovoltaic devices (600) to provide a tandem organic photovoltaic device includes a first hole transport layer (114), a first electron transport layer (112), and a metallic nanostructure layer (116) interposed between the first hole transport layer (114) and the first electron transport layer (112). The metallic nanostructure layer (116) provides an efficient recombination point for electrons and holes. The metallic nanostructure layer (116) can include silver nanowires which providing outstanding optical properties and permit the formation of the metallic nanostructure layer (116) using a low temperature, solution based, process that does not adversely affect underlying layers.

Description

[0001] background Technical field [0002] The present invention relates to organic photovoltaic devices, and particularly to intermediate layers for use with tandem organic photovoltaic devices. Background technique [0003] With increasing emphasis on carbon-neutral energy production, and assuming that the earth receives sufficient solar energy, photovoltaics are gaining attention as an attractive energy source. Currently, wafer-based crystalline silicon technology and processes have produced most photovoltaic devices, such as solar cells. Recent developments in organic photovoltaics, particularly in the development of thin-film-based organic photovoltaic devices using organic semiconductors, have shown increased efficiency, sometimes achieving efficiencies higher than 10%. Especially when compared with more conventional silicon wafer-based photovoltaics, due to the relatively easy handling of organic photovoltaic devices such as organic solar cells, inherent physical flexibili...
