Improved optical and electrical properties for heterojunction solar cell using Al2O3/ITO double-layer anti-reflective coating
بهبود خواص نوری و الکتریکی برای سلول های خورشیدی ناهمگون با استفاده از پوشش ضد انعکاس دو لایه Al2O3/ITO-2021 Silicon heterojunction solar cells have been gaining remarkable attention in the photovoltaic industry in recent
years owing to their low temperature coefficient and high efficiency. This study aimed to maximize the short
circuit current density (Jsc), which is directly correlated with the absorbance of the solar cells. An advanced ray
tracking model and hall effect measurement was used to improve the optical properties of Al2O3/ITO as a double layered anti-reflection coating (DLARC) on the solar cell. RF/DC power sputtering system was used to deposit
ITO layer, while atomic layer deposition was used to deposit Al2O3 on ITO to create a DLARC. An average
decrease in reflection from 9.33% to 4.74% and enhancement in EQE from 76.89% to 84.34% were observed for
the DLARC in the wavelength spectrum at 300–1100 nm. It also exhibited a higher Jsc value of 41.13 mA/cm2
and maximum conversion efficiency of 21.6%. The findings of both simulation and experiments showed that the
Al2O3/ITO DLARC has better anti-reflection properties than a single-layer ITO coating.

Dielectric surface coated with thin partially-reflecting mirror : A revisit to Fresnel laws
سطح دی الکتریک پوشیده از آینه نازک تا حدودی منعکس کننده: بازنگری در قوانین Fresnel -2020 New forms of Fresnel reflection and transmission coefficients were derived in the case of oblique
optical incidence at the interface of dielectric medium coated with thin partially-reflecting
mirror. This essentially required the application of modified boundary conditions for both the
electric and magnetic fields. The expressions for power reflectivity (of the mirror) were obtained
for both the transverse electric (TE) and transverse magnetic (TM) waves considering the cases of
dielectric and metallic coatings. The reflectance and transmittance of the coated surface were
also examined corresponding to different values of mirror reflectivity. It is expected that the
forms of Fresnel coefficients would be useful in modeling optical and optoelectronic mirror-based
devices. Keywords: Optical interaction | Fresnel coefficients | Reflective coating | Geometrical optics |
