Fig. 5: Impact of active layer thickness on thermal stability.
From: Hexanary blends: a strategy towards thermally stable organic photovoltaics
The time T95 for binary (B2) and hexanary devices (H1) to reach 95% of their initial PCE upon annealing at 130 °C, measured for different active layer thicknesses (for H1 devices T95 had not been reached at the end of the 14-day stability test). The active area of each pixel is 0.1 cm2. Source data are provided as a Source Data file.
