Vitamins for stable organic solar cells

Vida Engmann

Abstract

Organic solar cells have recently reached power conversion efficiencies of over 19%, highlighting the stability as their last remaining weak point. Their organic nature makes them strongly influenced by stresses such as oxygen, light, heat and humidity, which can be commonly found in their working environment. 

Incorporation of stabilizing additives (antioxidants, radical scavengers, hydroperoxide decomposers, UV absorbers) in active layers of organic solar cells is an attractive approach for inhibiting degradation as it is both inexpensive and easily upscalable, and it does not introduce further complexity into the device architecture.

Here we present our recent results on long-term stability improvement using naturally occurring antioxidants, such as vitamin C and beta-carotene, that act as singlet oxygen quenchers and radical scavenging compounds, as well as explore the synergistic effects of such compounds on the mechanical properties. The reported results and methods indicate a desirable route for mitigating degradation in organic solar cells.
