Reliability Analysis of III-V Solar Cells Grown on Recycled GaAs Substrates and an Electroplated Nickel Substrate

Figure 2

(004) XRD rocking curves of solar cell device epilayer and GaAs substrates (the 𝑦-axis is shown in linear scale).The left insert figure is GaAs substrate after epitaxial lift-off and without chemical cleaning; right insert figure is solar cell device epilayer transferred to the Ni substrate.
