ABSTRACT:
Photovoltaic generation of voltages well above the bandgap results upon absorption of radiation by a dipolar dopant within a transparent polarized pyroelectric body. Generation is by a charge transfer mechanism in accordance with which electrons are transferred from excited absorbing species. A photovoltage of greater than a thousand volts has been observed in Fe.sup.2.sup.+ -doped LiNbO.sub.3.
