Figure 1. Schematic configuration and the tunability of optical resonance.

Figure 1

Cross-sectional schematic diagram of TFSCs (a), and three-dimensional (3D) diagram (b) of the ultrathin a-Si:H solar cells with a tetragonal array of arranged TiO2-nanospheres, and ITO coating upon the front of the a-Si:H layer. Photocurrent density (Jph) versus the lattice constant: P (c) and the diameter of TiO2 nanospheres: D (d).
