Color control in Cu(In,Ga)Se2 (CIGSe) solar cells for BIPV via the lift-off method and light interference transparent conductive oxide layers fabrication

For Building-Integrated Photovoltaics (BIPV), the ability to produce a variety of colors is essential for architectural harmony. However, Cu(In,Ga)Se 2 (CIGSe) solar cells naturally have a rough growth surface that scatters light, significantly reducing the saturation and purity...
