Abstract Scope |
Bulk heterojunction organic photovoltaic devices may be produced via a process that involves solvent casting or printing liquid crystalline monomeric materials onto a substrate and then photocrosslinking them. The materials may be photopatterned during crosslinking. The fabrication process involves coating and crosslinbking a liquid crystalline polymer/solvent gel, removing the liquid crystalline solvent to form an aerogel, and then intercalating a second organic semiconductor material into the air-filled voids in the aerogel. In one material combination the liquid crystalline polymer is electron donating and the intercalated material is electron accepting. Liquid crystalline semiconductor materials have multiple advantages over equivalent amorphous organic semiconductors such as higher mobilities and the ability to easily mix multiple semiconducting materials with varying spectral light absorption bands. Current highest performance organic photovoltaic materials may be adapted for use in these devices. |
