Recently, the power conversion efficiency ($\mathit{PCE}$) of organic photovoltaic (OPV) cells has been improved through increased photocurrent density. To further increase $\mathit{PCE}$, open circuit voltage ($V_{\text{oc}}$) should also be increased. Here, we report tandem OPV cells based on low-molecular-weight semiconductors evaporated in vacuum. The tandem system produced a high $V_{\text{oc}}$ that is proportional to the number of tandem OPV cells. We obtained a $V_{\text{oc}}$ of 2.07 V using a quadruple cell, which was fourfold that of a single cell.
