Question:ningcuidi
ted to convert light energy into thermal energy loss in PN junctions, so there will be a complex carrier conversion efficiency and symbol Nint said.
Nint= (total number of photon number/composite-carrier composite carrier) x100%
Of course, it's hard to calculate the total number and total number of photons generated composite carrier. Typically by measurement of LED light output power to assess the efficiency, this efficiency Nint is known as quantum efficiency.
