Degradation pathways in standard and inverted DBP-C₇₀ based organic solar cells.

ABSTRACT: Achieving long-term stability in organic solar cells is a remaining bottleneck for the commercialization of this otherwise highly appealing technology. In this work, we study the performance and stability differences in standard and inverted DBP/C₇₀ based organic solar cells. Differences in the charge-transfer state properties of inverted and standard configuration DBP/C₇₀ solar cells are revealed by sensitive external quantum efficiency measurements, leading to differences in the open-circuit voltages of the devices. The degradation of standard and inverted solar cell configurations at ISOS aging test conditions (ISOS-D-3 and ISOS-T-3) was investigated and compared. The results indicate that the performance drop in the small molecule bilayer solar cells is less relat
