Recent Advances in Bulk Heterojunction Polymer Solar Cells.
Effects of additives on the morphology of solution phase aggregates formed by active layer components of high-efficiency organic solar cells.
It is concluded that DIO selectively dissolves PC(71)BM aggregates, allowing their intercalation into PTB7 domains, thereby optimizing both the domain size and the PTB 7-PC( 71)BM interface. Expand
Development of new semiconducting polymers for high performance solar cells.
A new low band gap semiconducting polymer, PTB1, was synthesized and found promising for solar energy harvesting, and an external quantum efficiency of 67% and fill-factor of 65% are achieved, both of which are among the highest values reported for a solar cell system based on a lowBand gap polymer.
