The phrase "achieved efficiencies" is correct and usable in written English.
It can be used when discussing improvements in productivity or effectiveness in a process or system.
Example: "The new software implementation has significantly achieved efficiencies in our workflow, reducing the time needed for project completion."
Alternatives: "realized efficiencies" or "gained efficiencies".
So far, plastic cells have achieved efficiencies of only 2.5%, against 10% for standard inorganic solar panels and 30% in the most expensive modules.
More than 100 such machines were subsequently built all over the world; they achieved efficiencies up to 75 percent at full load with heads up to 107 metres.
On hard problem instances, we achieved efficiencies as high as 80%, for a speedup of 26,215 on 32K processors.
Next Step: Although the cells' electron transport was better, their overall light conversion efficiency was low compared to that of some nanoparticle-based solar cells (which have achieved efficiencies of up to 10percentt).
The detector was used in a EUROBALL experiment, with achieved efficiencies of 80% and 63% for protons and α particles, respectively.
On the other hand, the volumetric ratio of VDES/VFuel = 3 1, achieved efficiencies of 100% and 97.79% after two extraction stages only.
And then, as the production achieved efficiency, the last ones would cost less.
The maximum achieved efficiency is about 5%, although with another loudspeaker the efficiency would be different.
The third region that achieved efficiency equal to 1 is the Nitra region in 2009.
(The most efficient power plants can achieve efficiencies of nearly 60percentt).
Now Grätzel, along with Peng Wang, a professor at the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, have made efficient solar cells that use nonvolatile electrolytes, with the best achieving efficiencies of 10percentt.
