Low bandgap photovoltaic cell with inherent bypass diode.

abstract:
A photovoltaic (PV) cell with a single pn-junction is disclosed that is
capable of functioning as both a current source and a bypass diode. The
photovoltaic cell is made of material that has a low bandgap energy, 1.0
eV, or less. One version of the PV cell is formed of a GaSb wafer doped
with Te to form an n-region; the Te concentration is between 6 and
10.times.10.sup.17 atoms/cm.sup.3. Multiple PV cells of this invention can
be connected in series or in parallel or in tandem in a primary-booster
tandem pair to form a circuit without the requirement of protecting the
individual cells of the circuit with a separate bypass diode.
