Electrochemical Deposition of Cu_xSn_yS_zO Thin Films and Their Application for Heterojunction Solar Cells

Figure 1

Schematic illustrations of (a) the CTSO/ZnO superstrate heterostructure and (b) the ZnO/CTSO substrate heterostructure. For the substrate structure (b), the light should be incident on the ZnO side through a transparent electrode. However, since the metal electrode was deposited on ZnO, the light was incident on the substrate side in the measurement.
