The operation of a polymer solar cell is governed by the key steps of light-absorption, charge generation and charge collection. When light is absorbed by a conjugated polymer, an exciton (bound electron-hole pair) is created. To generate a photocurrent these excitons need to be split up into free charges.
Understanding the formation of such CT states is critically important to optimise the efficiency of charge separation in a polymer solar cell. Polymer cells can be made with a power conversion efficiency of 9%, which is still somewhat lower than that of inorganic silicon solar cells with efficiencies on the order of 15%.
In many materials a Charge Transfer (CT) state is formed, in which electron and hole remain bound at the interface. Understanding the formation of such CT states is critically important to optimise the efficiency of charge separation in a polymer solar cell.
Following a development programme funded by the Carbon Trust, a start-up company called Eight19 has been created to manufacture efficient and inexpensive solar cells using organic semiconductor materials. Organic semiconductors are attractive as the active layer in solar cells since they can be deposited cheaply by printing over large areas.
The process of generating charges following light absoprtion takes place at the interface between two different organic semiconductors, and we are currently investigating the complex physical processes that occur at polymer interfaces in order to improve the efficiency of organic solar cells.
