1. Synthesis and Modification of Conjugated Materials for Polymer Solar Cells
Abstract : Polymer solar cells have emerged as a promising alternative to silicon based solar cells. One of the advantages of polymer solar cells is the possibility to use roll-to-roll techniques for large-scale device production. However, in order to fully utilize this technique, several issues need to be resolved. READ MORE
