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.
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.
