Abstract
We present the tandem solar cells consisted of amorphous silicon solar cells and polymer solar cells. Light absorption at the wide spectrum could be realized by the series-connection of the photoactive materials with the different band gaps. The fill factor of the tandem cells is mostly determined by that of the limiting cell. We found the interfacial contact between the inorganic and organic layers plays an important role in improving the fill factor. The current density-voltage characteristics of the tandem cells are predicted by a calculation with the characteristics of the single sub-cells. In this study, we obtained the experimental result that is very contiguous to the calculated result as shown in Figure 1 and Table 1. By employing the solution-processed polymer solar cells, the cost for the fabrication of tandem cells can be significantly reduced. Our study opened up the new conceptual and cost-effective hybrid tandem cells.
