Abstract:

Bulk heterojunction BHJ solar cells were invented at UC Santa Barbara after the fundamental discovery of photoinduced ultrafast electron transfer from conjugated polymers to fullerenes. Many groups in the U.S., Europe and Asia are now making important contributions. Nevertheless, the UCSB group remains one of the leaders in the field. The high charge separation efficiency, the reduced fabrication costs associated with solution processing printing and coating and the implementation of this robust self-assembled technology on flexible substrates make plastic solar cells a compelling option for tomorrow s photovoltaics.
