What Is Solar Cell Efficiency. When discussing solar cell efficiency, we mean the amount of sunlight that hits a solar panel and is converted into electricity. A solar panel is only as efficient as its weakest link: the cell. Cells, made of silicon, absorb photons and convert them to electricity.
The total absorption of the solar cell is: Emission flux. The emission from the solar cell depends on the quasi-Fermi level separation (μ) of the solar cell. Under short circuit conditions, m is zero. The emission is calculated by: φ 2 E G, ∞, μ, T E a r t h = 2 π h 3 c 2 ∫ E G ∞ E 2 e x p E-μ k T E a r t h-1 d E
