 Graphene Energy

Graphene for Use in Energy Photovoltaics
Given its transparency, conductivity, mechanical strength, high surface area, and tunable band gap, graphene can fill several different roles in photovoltaic devices including as a transparent electrode and as a electron transport layer. High efficiencies have been achieved using molybdenum trioxide and zinc oxide layers in graphene based solar cells.

Graphene for Use in Hydrogen Storage

Graphene for Use in Energy Fuel Cells
Graphene has been used as a proton exchange membrane for use in hydrogen fuel cells. Importantly, the graphene must have specific defects when used for this application.

Graphene for Use in Next-Generation Batteries
Graphene composite materials have been used to increase discharge rates, energy densities, and cycle performance in anodes used in lithium ion batteries. Other potential benefits of using graphene composite anodes in lithium ion batteries include increased battery capacity, charging time, and battery life.

Graphene for Use in Supercapacitors
Carbon-based materials with especially high surface areas are widely used as electrode materials in double-layer capacitors due to their excellent physical and chemical properties. First generation graphene-based supercapacitors have been shown to store as much energy as nickel-metal hydride batteries.
