Abstract
A laminated graphene device is demonstrated as a cathode. In one example the devices include organic photovoltaic devices. The measured properties demonstrate work-function matching via contact doping. Devices and method shown also provide increased power conversion efficiency due to transparency. These findings indicate that flexible, light-weight all carbon devices, such as solar cells, can be constructed using graphene as the cathode material.
