Inhibiting Photo-oxidative Degradation in Organic Solar Cells using Stabilizing Additives

Biomimetic Approach to Inhibition of Photooxidation in Organic Solar Cells Using Beta-Carotene as an Additive

“…[29][30][31] These light-initiated degradation processes can be mitigated in different ways: device encapsulation, 11,32 introducing oxygen "getter" and UV blocking functionalities, [33][34][35] developing more stable organic materials, [36][37][38] and the addition of radical inhibitors and singlet oxygen quenchers (i.e., additive-assisted stabilization). [39][40] The latter approach, which is routinely used with commodity plastics, 24 comes with no added complexity and expense in the device processing. Of course, the requirements placed on the stabilizers for use in an OPV are strict.…”
