Abstract
In this abstract, Si nanohole and nanowire/organic polymer solar cell is fabricated by low temperature and simple spin-coating method. The results show that the nanohole device performance is better than that of nanowire device. The Si nanohole device has higher external quantum efficiency in all wavelengths. The reason for the enhancement is analyzed from optical reflectance and the observation between Si nanohole and PEDOT:PSS interface. With nanohole structure, the short-circuit current density is increased from 22.1 to 26.9 mA/cm2 (22% increase), and the power conversion efficiency is enhanced from 7.4% to 8.0%. Nanohole structure is promising for high-efficiency Si/organic polymer solar cell. © 2013 IEEE.
