Towards the optimization of organic solar cells via controlled morphologies
MetadataShow full item record
We present a combined experimental and theoretical analysis of organic solar cells based on bulk heterojunctions. Our simulation based on a drift-diffusion approach shows that a cell with controlled morphology can lead to improved performance. Two ways to realize such structure are identified, based respectively on patterning via nanoimprint techniques and by the use of vertically grown ZnO nanorods. Preliminary results for the two paths are provided.
