Silicon Solar Cell Parameters
The front surface is textured to increase the amount of light coupled into the cell. Emitter Dopant (n-type) N-type silicon has a higher surface quality than p-type silicon so it is placed at the front of the cell where most of the light is absorbed.

What is the optimum doping concentration for solar cells?
This has effects on the solar cells properties. It is so there is optimum doping concentration both in the substrate and emitter layers of the solar cells. As an example for silicon single crystal solar cells it is found that the optimum doping in the substrate is 10^17/cm^3 and in the emitter it amounts to 10^19/cm^3.
How to evaluate the performance of solar cells?
The performance of the solar cells can be evaluated by making a profound analysis on various effective parameters, such as the sheet resistance, doping concentration, thickness of the solar cell, arbitrary dopant profile, etc., using software simulation tools, such as PC1D.
How are doping profiles approximated?
The doping profiles are approximated by error functions that give the best fit to the experimental data. However, these might not possess the same shape of the doping profiles obtained experimentally. Particularly, the peak surface concentrations for the simulated profiles are overestimated, which might reduce the cell potential.
Can a low surface concentration improve a solar cell's blue response?
After which, the EDNA2 simulation tool was used to analyse the emitter saturation current density for the chosen arbitrary dopant profile. Results indicated that the diffusion profile with low surface concentration and shallow junction depth can improve the blue response at the frontal side of the solar cell.
Which recombination models are used to calculate surface velocity?
In the present study, we applied the following models: Trupke radiative recombination [ 18 ], Ritcher Auger recombination [ 19 ], Shockley–Read–Hall (SRH) recombination [ 20] to calculate the effective surface recombination velocity (as 1× 10 cm/s).
