Latest Patents

Fraas holds a patent for a photovoltaic cell and array with an inherent bypass diode. This invention features a photovoltaic cell capable of functioning as both a current source and a bypass diode. The cell is constructed from a material with a low bandgap energy of 1.0 eV or less. One version of this cell is made from a GaSb wafer doped with Te to create an n-region. The concentration of Te is maintained between 3 and 15 × 10^17 atoms/cm^3. This innovative design allows multiple photovoltaic cells to be connected in series and placed in parallel with other cells that do not function as tunnel diodes, forming a power-generating array. The arrangement of the cells in tandem pairs ensures that if one cell becomes inactive, current can still flow through it, minimizing the drop in output current from the array.
