Wavelength-scale analysis of influence of chirped DBRs on optical characteristics of multinanolayer photovoltaic cells

Influence of Chirped DBR Reflector on the Absorption Efficiency of Multi-nanolayer Photovoltaic Structures: Wavelength-scale Analysis by the Method of Single Expression

“…All PV structures are based on a Si p-i-n type absorber and supported by a metallic mirror (Cu) and SiO 2 substrate. The results of a preliminary analysis of the thin-film multinanolayer PV structure with chirped DBR on the top of the structure was presented at ICTON 2016 [22]. Chirped DBR mirrors should possess broadband reflective features in the range of 350-750 nm in the vicinity of the central wavelength of 550 nm of the sun's maximal radiation.…”
