Abstract

The series interconnection of organic photovoltaic cells on the scale of several hundred nanometres results in 1390 interconnected elementary cells per mm. This organic photovoltaic nanomodule generates the highest reported voltage per length for an organic photovoltaic device. As a first application we demonstrate the switching of an organic field effect transistor with a 590 µm wide photovoltaic nanomodule providing a sufficiently high gate voltage.
