I am trying to figure out how to implement transfer matrix method to calculate how much of solar power gets absorbed in each layer. I am readying "Modeling photocurrent action spectra of photovoltaic devices based on organic thin films" by L. A. A. Pettersson, L. S. Roman, O. Inganas.
According to the equation I attached, I can calculate the internal electric field propagating in the positive x direction in layer j. I can calculate the term in front of E0+, but I am not sure what to plug in for E0+. What would be the electric field intensity of sunlight using AM1.5G?
The reflection coefficient and transmission coefficient are specific to a certain wavelength, then how does that apply to sunlight? Do I need the irradiance of sunlight at specific wavelength? How do I calculate that?
Dear Mr. Kim,
It is so the power density p is related to the electric field E where
p= E^2/Z0 where E is the effective value of the electric field and Z0 is the characteristic impedance. Z0 in the air is known where it is equal to 377 Ohm.
You can get the reflection coefficient and the absorption efficient from the material properties. They apply to sun light by considering them at the wavelength of the light and frequency.
Inside the material p= E^2/ Z0 in the material.
You can get the spectral power density p from the spectral power curve of the incident solar radiation at say AM1.5. It is the AM1.5 illumination curve.
Best wishes
Dear
First of all set the parameters for finding the transfer function of the system, and after calculating the desired values, implement it to real circuit to achieve the actual results.
Actually, This is done by taking the Laplace transform of the differential equation of the LTI system and observing that the convolution of the input and the system equation just becomes the product. This leads to writing down the transfer function as the ratio of the output over its input in the transform domain.
Hope this link will help you to understand it.
