Popis: | We report on the proof of principle of a III–nitride/silicon tandem solar cell. Photovoltaic activity is demonstrated in a 0.25 cm2 dual junction solar cell, made of p- and n-type GaN layers which were grown by molecular beam epitaxy (MBE) on a standard n-type Si wafer with an Al doped p-type surface. An open circuit voltage (Voc) of 2.4 V was measured under 1× sun AM1.5G condition with additional UV laser illumination of the GaN junction. Experiments under various illumination conditions were performed to verify that both junctions are active and working in series. |
