Olsen, L. C., Bohara, R. C. & Urie, M. W. Explanation for low efficiency Cu2O Schottky barrier solar cells.
The Net Present Value was positive for only two scenarios and for low efficiency, low hydrolysis points.
This result suggests that greater EPBT savings are obtained for low efficiency module recycling, especially when considering framed modules whose aluminum materials make up between 50% and 70% of the embodied energy.
Collaborative optimization based on the lamination parameters can optimize the composite pressure hull effectively, as well as provide a solution for low efficiency and non-convergence of direct optimization with design variables.
For low efficiency and poor high-temperature resistant performance of the conventional artificial lift systems, a new sliding vane pump and the matched lift system were designed, and the pump property study, field test and economy analysis were conducted.
Experimental results reveal that the downstream guide vanes are more responsible for low efficiency of the turbine and it is measured that 21% average pressure is lost due to downstream guide vanes.
Unfortunately, owing to its wide electronic bandgap (3.0 to 3.2 eV), TiO2 absorbs only an ultraviolet fraction of a solar spectrum (which accounts for just 4% of solar irradiation), being consequently responsible for low efficiency in utilization of solar light[2, 7, 9].
For low efficiency reactions, Conversion of substrate to product was quantified as follows.
In bacteria and many eukaryotes, though not necessarily in other eukaryotes such as mammals, the first ∼10 codons after the start AUG in mRNAs are enriched for low efficiency codons and the RNA secondary structure in this 5′ region is less stable than that in other regions of the mRNAs [10 15].
