However, those researches lack discussion of how to improve the EM energy conversion efficiency
. In addition, the establishment of a control map requires extensive experimental data as a practical foundation (which means it would be difficult to use in product development phases of the vehicle).
Amorphous silicon technology is less widespread, as it offers lower efficiency, lower longevity, and higher degradation rates than its competitors [International Energy Agency 2014], Although First Solar has steadily improved the average energy conversion efficiency
of its cadmium telluride solar modules to more than 14.0 percent, plummeting polysilicon prices in recent years have reduced thin-film modules' cost advantage.
Under illumination with a simulated solar light of 100 mW [cm.sup.-2] (AM 1.5), the photovoltaic parameters of the DSSCs including short circuit photocurrent density ([J.sub.SC]), open circuit voltage ([V.sub.OC]), FF, and the light-to-electric energy conversion efficiency
([eta]) are listed in Table 2.
Their usage is limited because of the low energy conversion efficiency
and high costs.
As for bare solar cells, the average energy conversion efficiency
of 20 cells after 500 h of exposure degraded by 5-6%, which is higher than the data of sealed cells.
Three papers from Yunnan Normal University produce fatty acids from soybean oil through lipase catalysis, assess the inhibition effect of fusarium oxyspomm with bioslurry, and measure the energy conversion efficiency
of sorghum distilled residue biogas fermentation.
The energy conversion efficiency
from electrical energy from the grid to turning the wheels for electric vehicles is about three times greater compared to the energy conversion efficiency
from the energy stored in gasoline to turning the wheels for gasoline vehicles.
Energy conversion efficiency
is very important for the solar power generation system.
For example, in the PV sector, there is a growing emphasis on energy conversion efficiency
as solar subsidies begin to go away and as panel prices are on a relentlessly downward trend.
Both energy conversion efficiency
and C sequestration by bamboo forest in subtropical China (Table 2) were quite high.
