Abstract:
Organic polar crystals from the donor–acceptor substituted 1,4-diphenybutadiene 1 can generate a short-circuit photocurrent
and a photovoltage upon illumination with near UV light. The photocurrent and photovoltage are attributed to a bulk photovoltaic effect. The bulk photovoltaic effect has been known for inorganic polar crystals for decades and can now also be demonstrated for organic polar crystals.
