Abstract
The present disclosure relates to a cellulose-polymer composite solar cell that is substantially biodegradable and fabricated using environmentally friendly materials and methods. The polymer solar cell comprises an electrically conductive cellulose-polymer composite and an electrically semiconductive cellulose-polymer composite.
Claims27
A composite polymer, comprising:
- a) a cellulose composite comprising
- i) cellulose or a cellulose derivative;
- ii) a phosphonium ionic liquid;
- and
- iii) a conductive polymer;
- and
- b) optionally, an electrically conductive dopant,
- wherein the cellulose or cellulose derivative is dissolved in the phosphonium ionic liquid and the phosphonium ionic liquid is incorporated into the cellulose or cellulose derivative, and the cellulose or cellulose derivative is bound to the conductive polymer.
