In contrast, the findings suggest that sheet resistance values can be reduced from previously 550 Ω sq −1 down to 250 Ω sq −1 without compromising subcell current. This reduction can be achieved by implementing a 3 × 10 17 cm −3 silicon-doped, 840 nm thick Ga 0.51 In 0.49 P rear–heterojunction solar cell in the quadruple–junction device.
The effective contact resistivity and emitter sheet resistance between two fingers in each strip were measured and compared to quantify the contact degradation induced from longer field aging. The Arizona module suffered from higher resistance as compared to the Florida module due probably to longer field exposure and higher operating temperatures.
Together with the absorption–based calculated thicknesses of absorbers, the sheet resistances of possible current–matched AlGaInP rear–heterojunction solar cells with bandgap energies of 1.90 and 1.94 eV have been determined for different doping concentrations.
The Arizona module suffered from higher resistance as compared to the Florida module due probably to longer field exposure and higher operating temperatures. This method serves as a good diagnostic tool to anticipate and understand the severity of the contact degradation of solar cells in the fielded modules.
The electrical performance of a photovoltaic (PV) module is greatly hindered by the existence of parasitic resistance losses, such as high series resistance (R s ) and low shunt resistance (R sh ). Contact resistance at metal grid/semiconductor interface and emitter sheet resistance are two major contributors to cell R s .
This reduction can be achieved by implementing a 3 × 10 17 cm −3 silicon-doped, 840 nm thick Ga 0.51 In 0.49 P rear–heterojunction solar cell in the quadruple–junction device. The integration of this optimized GaInP cell would reduce the series resistance by about 5 mΩ cm 2 without limiting the current.
