Figure 5

Calculated and measured short-circuit current densities (J SC) of the transfer-fabricated tandem devices with different TAPC:C70 thicknesses (t). The calculated (line) and measured (circle) values of J SC for the transfer-fabricated tandem device shown in Fig. 1 as functions of t. The inset shows the photocurrent densities of the top (solid line) and bottom (dotted line) subcells as functions of t.
