    Improving the efficiency enhancement of photonic crystal based InGaN solar cell by using a GaN Cap Layer
    (Hindawi Publishing Corporation, 2014) Gundogdu, T.F.; Gökkavas, M.; Özbay, Ekmel
    We studied a high indium content (0.8) InGaN based solar cell design where the active InGaN layer is sandwiched between a GaN cap layer and a GaN spacer layer. The incorporation of the sacrificial cap layer allows for the etching of the front surface without removing the active InGaN resulting in a 50% enhancement of the short-circuit current density for a 15 nm-thick InGaN layer. © 2014 T.
