ZnO/a-Si Distributed Bragg Reflectors for Light Trapping in Thin Film Solar Cells from Visible to Infrared Range

Aqing Chen, Qianmin Yuan, Kaigui Zhu

Distributed bragg reflectors (DBRs) consisting of ZnO and amorphous silicon (a-Si) were prepared by magnetron sputtering method for selective light trapping. The quarter-wavelength…
