"Benefits of graphene for use in solar cells"

For all the attention graphene gets thanks to its impressive list of properties, how many of us have actually encountered it in anything other than its raw graphite form? Show of hands. No-one? That’s because it is still difficult to mass-produce without introducing defects. Now a team at the Korea Institute of Science and Technology (KIST) has developed a graphene substitute from plastic that offers the benefits of graphene for use in solar cells and semiconductor chips, but is easy to mass-produce.

The technique that currently shows the greatest potential for producing high quality graphene at large scales is chemical vapor deposition (CVD). This is a complicated eight-step process whereby gaseous reactants are deposited onto a metal film substrate that acts as a catalyst. Once the graphene is formed, it needs to be removed from the metal substrate and transferred to another board, such as a solar cell substrate, which runs the risk of wrinkling or cracking the graphene.
