The minority carrier lifetime of a material is the average time which a carrier can spend in an excited state after electron-hole generation before it recombines. Calculate the minority carrier lifetime (in ) for a single crystalline solar cell having diffusion length of and minority carrier diffusivity of .
To calculate the minority carrier lifetime in a single crystalline solar cell, you need to use the formulas for diffusion length (L) and minority carrier diffusivity (D), along with the relationship between these values and the minority carrier lifetime (τ).
The formula to calculate minority carrier lifetime (τ) is:
τ = L^2 / D
Given:
Diffusion length (L) = <<Diffusion Length>> (units)
Minority carrier diffusivity (D) = <<Minority Carrier Diffusivity>> (units)
First, you need to substitute the given values into the formula:
τ = (<<Diffusion Length>>)^2 / <<Minority Carrier Diffusivity>>
Now, substitute the given values into the formula and calculate the result:
τ = (<<Diffusion Length>>)^2 / <<Minority Carrier Diffusivity>>
τ = (<<Diffusion Length>>)^2 / <<Minority Carrier Diffusivity>>
= (<<Diffusion Length>>)^2 / <<Minority Carrier Diffusivity>>
= (<<Diffusion Length>>)^2 / <<Minority Carrier Diffusivity>>
= (calculate the square of the diffusion length)
= (result of the square) / <<Minority Carrier Diffusivity>>
= (final result)
After substituting the values and performing the calculation, you will get the minority carrier lifetime (τ) in units.
