Abstract:
Herein, we present an efficient approach for screening the intrinsic photostability of organic absorber materials used in photovoltaic applications. Using a series of structurally related conjugated polymers and a set of complementary techniques, we established important "material structure-photostability" relationships. In particular, we have revealed that the introduction of alkoxy, thioalkyl, and fluorine substituents adversely affects the material photostability. Further systematic screening of different types of materials using the developed techniques should yield a set of guidelines for designing more stable absorber materials for organic solar cells.

Stability of Conjugated Dienes
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.
π Molecular Orbitals of 1,3-Butadiene
The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the number...
