Study the effect of a single layer of anti-reflective coating (Ge)‎ on the quantitative efficiency of a silicon solar cell

Abstract EN

The objective of this research is to study the possibility of reducing the reflectivity of the front surface of a silicon cell (Si / Si) by using a theoretical design for a single-layer Antireflection Coatings with a thickness of one quarter of the design wavelength.

Then, Mathematical programs in MATLAB (10) were designed to study the quantitative efficiency of the cell as a function of the change in the particle size of the coating within the range (400 - 700 nm) wavelength of the visible state of the vertical and oblique state at the (45°) angle.

(Ge) was used as an anti-reflective material.

It was found that the highest quantitative efficiency was (96.9004%) at design wavelength (λ0= 550 nm) in the case of vertical fall.

Whereas, in the case of a sloping fall at an angle of (45o), a quantitative efficiency of (94.0545%) at vertical polarization (S).

In the case of horizontal polarization (P), the quantitative efficiency value is (96.3131%) when the particle size of the coating is (Ps = 4.4nm).
