My project involved working with organic solar cells (use organometals instead of purified silicon; function similarly) to reduce the cost of manufacturing cells while keeping similar energy efficiency. Specifically, my project involved working with special thermoelectric polymers which were used as semiconductors with the addition of graphene-based dopants to improve specifically a single layer (hole transport layer).
The layer improved served as the basis for electron-hole transfer and more efficient electron mobility. Improving this layer would greatly improve the efficiency of the overall cell and would be a large step towards switching out of the silicon standard. Future research include using sugar alcohols in addition to polymeric materials.
