← ScienceWhich mechanism limits silicon solar cell's maximum achievable energy conversion efficiency?
A)Surface recombination of electron-hole pairs✓
B)Thermal voltage drop across the module
C)Reverse saturation current increase
D)Electromagnetic interference from inverter
💡 Explanation
When photons excite electrons which move to respective energy bands, surface recombination reduces efficiency as surface defects trap electrons, leading to non-radiative recombination with holes reducing power available. Therefore surface recombination limits conversion efficiency rather than thermal voltage, saturation, or EMI, which represent distinct energy dissipation mechanisms or system interference sources.
