31. Here they are tested more accurately and evaluated for feed conversion efficiency , growth and muscle development. 32. So far, the conversion efficiency of nanorod polymer cells has been little more than 2 percent. 33. Typically, maximum conversion efficiency is attained at around 65 % to 80 % of full output. 34. However, this application faces many issues, given fundamentally low conversion efficiencies and competition from other sources. 35. Energy conversion efficiencies achieved to date using conductive polymers are very low compared to inorganic materials. 36. (3 ) Internal conversion efficiency reaches 100 %. 37. In 2010, a solar energy conversion efficiency of about 10 % was achieved in a CZTS device. 38. The conversion efficiency is very low, on the order of 1 pair per 10 12 incoming photons. 39. This led to an overall 20 % better Fed Conversion Efficiency as compared to the wild stock. 40. The alpha particles must slow down before they contact the collector plates to realize high conversion efficiency .
