11. A P-N junction can convert absorbed light energy into a proportional electric current. 12. This causes it to absorb less light energy and cool down. 13. However these cheaper crystals are less efficient at turning light energy into electricity. 14. Yeah OK, but theyre using high intensity visible light energy from the sun. 15. :Light energy can be focused pretty well with a Lens ( optics ). 16. LH2's fierce efficiency in harvesting and transmitting light energy is no mere parlor trick. 17. This would waste the high-energy electron and convert the absorbed light energy into heat. 18. This is the chemical reaction in which chemical energy is converted to light energy . 19. PECs convert light energy into electricity within a two-electrode cell. 20. Einstein postulated that light energy , too, is transferred in discreet amounts, later called photons.
