title = "The ultra triple-junction cell: High-efficiency solar cell for space applications", abstract = "Solar cells suitable for the space environment must combine high efficiency, high energy density, and radiation hardness in a manufacturable design. The UTJ cell builds on the extensive heritage of predecessor multijunction GaAs/Ge solar cells. As solar cell efficiency rises, more of the sunlight spectrum is converted to electrical power, resulting in greater satellite payload capability or — for equivalent power output capability — smaller, lighter solar arrays.

This characteristic can be modeled by the circuit shown in Figure 4. The diode is responsible for • 3rd generation triple-junction (ZTJ) InGaP/InGaAs/Ge Solar Cells with n-on-p polarity • Solar cell mass of 84 mg/cm2 • Fully space-qualified with proven large volume manufacturing and flight heritage • Excellent radiation resistance with P/Po = 0.90 @ 1-MeV, 5E14 e/cm2 fluence The spectral response is conceptually similar to the quantum efficiency. The quantum efficiency gives the number of electrons output by the solar cell compared to the number of photons incident on the device, while the spectral response is the ratio of the current generated by the solar cell to the power incident on the solar cell.

measurement of either solar cell voltage or solar cell current, thus further decreasing the component count. The SmartFusion FPGA analogue compute engine allows for increased performance of the perturb-and-observe algorithm implemented on the microcontroller sub- Introduction. Solar cells are devices which use the photoelectric effect to convert electromagnetic radiation that falls on them into electricity 1.They are constructed from a semiconductor material, like silicon, linked to a metal conductor and covered by a layer of anti-reflective glass that protects the semiconductor wafers from damage whilst still allowing light through.

The LEONE UTJ cell qualification program included thermo mechanical testing to 66,060 LEO and 15,549 GEO thermal cycles on multiple coupons; and radiation testing on bare cells. Inverted and normal gradient ESD testing was performed on CICs and multiple coupons to mitigate potential risk with use of large area cells on high voltage arrays. the large area cells as these are the most cost effective for the missions we supply to. The UTJ solar cells have dimensions of 39.70mm x 69.11mm. They are GaInP2/GaAs/Ge multi-junction cells, have an efficiency of about 29% and, equally as important for CubeSats have terminal voltage of over 2V (at least
