← ScienceWhich risk increases when a photovoltaic cell's depletion region narrows?
A)Increased electron-hole recombination rate✓
B)Enhanced free carrier lifetime
C)Reduced diffusion current in depletion
D)Improved built-in voltage strength
💡 Explanation
Increased electron-hole recombination results because a narrower depletion region reduces the electrical field’s ability to separate the electron and hole pairs effectively; this increases recombination occurring via Shockley-Read-Hall recombination, therefore, reducing the output, rather than others, causing efficient performance.
