Traditional techniques for indexing these collections fail to properly exploit their regularities in order to reduce space.
A multi-layered polymer solar cell (PSC) with a graded compositional profile to reduce space-charge limited (SCL) transport was designed and analyzed in details.
The findings provide insights for building designers, owners, operators, and energy policy makers to make better decisions on energy-efficiency technologies to reduce space-heating energy use for both new and existing buildings.
A sound argument for integrating such spatial effects is provided by the fact that there is not only a substantial effect on crown and branch development (Seifert [2003]), but also first evidence that spatially irregular growing conditions reduce space-use efficiency (Ackerman et al. [2013]).
A larger nanorod diameter will reduce spacing between NRs, which contributes to a reduction in the amount of solar absorber.
To reduce space-clamp-induced errors, we made dendritic recordings, as we described previously [39], [40].
