Computational analysis of the refractive index of multiple quantum wells for QWSC applications

Computational modelling of the reflectivity of AlGaAs/GaAs and SiGe/Si quantum well solar cells

“…This can be done through the models documented in Refs. [2][3][4][5]. In all the individual alloy layers to make up the QWSC; the effects of molar concentration and operating temperature on the refractive index of these alloy layers can be determined using the equations and techniques established in Refs.…”

“…In all the individual alloy layers to make up the QWSC; the effects of molar concentration and operating temperature on the refractive index of these alloy layers can be determined using the equations and techniques established in Refs. [3,4]. This is simply done by representing the band gap (E g ) parameter equation for each respective layer of the cell with a function of molar concentration and temperature.…”

“…The model is based on the MSEO model [2] combined with the work on the refractive index of quantum wells [3][4][5] and Frensel's formula [6]. The model generates the reflectivity of a QWSC for a given concentration level, configuration, electric field and operating temperature.…”

“…In order to do this, the author puts forth a new approach to modelling the reflectivity of the QWSC. The model presented here is based on a theoretical model of the refractive index of the QWSC established elsewhere [2][3][4][5] combined with the Fresnel formula [6].…”

“…The MSEO model allows the calculation of the refractive index of a semiconductor layer. In the previous works [3][4][5] investigations into the three major areas essential to design and determining the QWSC's refractive index are performed. These major areas are:…”
