文摘

The characteristics of short circuit current (I \(_\mathrm{sc})\) in dual-junction GaInP/GaAs solar cells have been investigated, and the experimental results show that the photo current of GaInP top cell is higher than that of GaAs bottom cell and the I \(_\mathrm{sc}\) of the device is usually not limited by GaAs bottom cell if a leakage current occurs. The current versus voltage (I鈥揤) curves of the solar cell were simulated with subcells based on single diode model and the I \(_\mathrm{sc}\) shows a dependence on the leaky subcells, i.e., the I \(_\mathrm{sc}\) is between the photo current of GaAs and that of GaInP subcells in the case of a leaky GaAs subcell, it is equal to the photo current of GaAs subcell in the case of a leaky GaInP subcell, and it is lower than the photo current of GaInP subcell when both GaAs and GaInP subcells are leaky.
