TL;DR: In this article, a combination of in situ currentvoltage measurements and grazing-incidence wide-angle X-ray scattering experiments at elevated temperature was used to correlate the changes in photoconversion efficiency to changes in the molecular ordering of a poly(3-hexylthiophene):[6,6]-phenyl-C61-butyric acid methyl ester (P3HT:PCBM) bulk heterojunction active layer.
Abstract: Bulk heterojunction organic solar cells hold much promise as commercially viable sources of renewable energy due to their relatively inexpensive fabrication. Developing a fundamental knowledge of how processing conditions influence solar power conversion efficiency will enable rational and efficient design, optimization, and control of new organic solar cell materials. In this report, we use a combination of in situ current–voltage measurements and grazing-incidence wide-angle X-ray scattering experiments at elevated temperature to correlate the changes in photoconversion efficiency to the changes in the molecular ordering of a poly(3-hexylthiophene):[6,6]-phenyl-C61-butyric acid methyl ester (P3HT:PCBM) bulk heterojunction active layer. In situ measurements of current–voltage characteristics were used to optimize the power conversion efficiency and the resulting thermal processing was in agreement with studies from repeated heating and cooling cycles. The improvements in short circuit current with thermal annealing were correlated to an increase in the population of face-on oriented crystallites of P3HT rather than improvements in molecular ordering of PCBM.

Journal ArticleDOI
TL;DR: In this article, the storage of solar energy as formic acid generated electrochemically from carbon dioxide has been identified as a viable solar fuel pathway, which can be accomplished by separating light absorption and CO 2 reduction through the use of a commercial solar panel illuminated with natural AM 1.5 sunlight to power a custom closed-loop electrochemical flow cell stack.
Abstract: The storage of solar energy as formic acid generated electrochemically from carbon dioxide has been identified as a viable solar fuel pathway. We report that this transformation can be accomplished by separating light absorption and CO 2 reduction through the use of a commercial solar panel illuminated with natural AM1.5 sunlight to power a custom closed-loop electrochemical flow cell stack. Faradaic yields for formate of up to 67% have been demonstrated in this system, yielding a solar energy to fuel thermionic conversion efficiency above 1.8%.
