Methods and systems of organic semiconducting polymers
An organic photovoltaic device comprising a polymer: and an acceptor. In this organic photovoltaic device, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are independently selected from the group consisting of: a halogen, a substituted alkyl, an unsubstituted alkyl, a substituted aryl, an unsubstituted aryl, a substituted heteroaryl and an unsubstituted heteroaryl.
1. An organic photovoltaic device comprising:
a polymer:
and an acceptor,
wherein R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are independently selected from the group consisting of:
a halogen, a substituted alkyl, an unsubstituted alkyl, a substituted aryl, an unsubstituted aryl, a substituted heteroaryl and an unsubstituted heteroaryl,
wherein the ratio of m is between 0.6 to 0.8 and n is between 0.2 and 0.4.
2. The organic photovoltaic device of claim 1 , wherein the acceptor is a fullerene acceptor.
3. The organic photovoltaic device of claim 1 , wherein the acceptor is a non-fullerene acceptor.
4. The organic photovoltaic device of claim 1 , wherein R 3 R 4 , R 5 , R 6 are independently selected from
wherein R is independently selected from the group consisting of: a halogen, a substituted alkyl, an unsubstituted alkyl, a substituted aryl, an unsubstituted aryl, a substituted heteroaryl and an unsubstituted heteroaryl.
5. An organic photovoltaic device comprising:
