6 FAQs about [Analysis of the causes of solar cell buzzing]
Which factors affect the loss process of solar cells?
The external radiative efficiency, solid angle of absorption (e.g., the concentrator photovoltaic system), series resistance and operating temperature are demonstrated to greatly affect the loss processes. Furthermore, based on the calculated thermal equilibrium states, the temperature coefficients of solar cells versus the bandgap Eg are plotted.
Which loss processes are unavoidable in single bandgap solar cells?
Among the loss processes, the below E g loss and the thermalization loss play dominant roles in energy loss processes. These two kinds of loss processes are unavoidable in traditional single bandgap solar cells for the mismatch between the broad incident solar spectrum and the single-bandgap absorption of a cell [10, 12].
How does a high concentration ratio affect the emission loss of solar cells?
For solar cells at high concentration ratio (e.g., n = 100), the output photocurrent density is very high, and thus according to Eq. (11), (12), the emission loss is greatly enhanced for solar cells in radiative limit (ERE = 1), while for real solar cells (ERE≠1), the NRR-J loss is greatly enhanced and the NRR-V loss becomes negligible.
How do cell parameters affect photovoltaic loss processes?
Considering that the parameters of the cells greatly affect the loss processes in photovoltaic devices, the sensitivities of loss processes to structure parameters (e.g., external radiative efficiency, solid angle of absorption, resistances, etc.) and operating parameters (e.g., operating temperature) are studied.
What causes recombination in solar cells?
In practical solar cells, structural defects or impurities are very common, and they generally result in the recombinations of the electron-hole pairs, especially the non-radiative recombinations (e.g., Shockley-Read-Hall recombination), reducing the carriers lifetime or suppressing the cell efficiency .
Why is voltage loss enlarged in a photovoltaic cell?
As for the voltage losses, the components due to Carnot loss, angle mismatch loss and NRR loss are all enlarged for they are proportional to the temperature of the cell, and the component due to series resistance varies with output photocurrent density, for it is proportional to J2MPP-f.
