Problems solved by technology

A series connection has a disadvantage: the area of ​​the surface exposed to light is reduced
Alternatively, if no fine mask is available, the gap between organic solar cells will be very large (in the range of 1mm or more)

Abstract

The present invention concerns a method for forming an electrical interconnection in an organic photovoltaic device, the method comprising steps of providing a first conductive layer (31), providing an organic photovoltaic layer (32), over the first conductive layer, providing a second conductive layer (33), over the organic photovoltaic layer, and providing an electrical interconnection between the first conductive layer and the second conductive layer.

Description

technical field [0001] The present invention relates to methods of forming electrical interconnections in organic photovoltaic devices and to organic photovoltaic devices. Background technique [0002] Organic photovoltaics (OPVs) offer great promise for efficient and large-scale conversion of light to electricity. The production of organic photovoltaic devices requires less material than the production of inorganic crystalline photovoltaic devices. Such production also consumes considerably less energy than the production of any other inorganic photovoltaic device. [0003] The efficiency of organic photovoltaic devices is steadily increasing. In 2008, a certified power conversion efficiency value of 5% was achieved, and in 2010, the psychological barrier of 8% was broken, bringing the efficiency of organic photovoltaic devices on par with typical values ​​for amorphous Si devices. [0004] An OPV device includes at least one solar cell, or arrangement of solar cells. O...
