Linear and non-linear optical properties of boron carbide thin films

Annealing-induced phase transformation in In10Se70Te20 thin films and its structural, optical and morphological changes for optoelectronic applications

“… 83 The lower value of ε ∞ compared to ε L is due to the contribution of free charge carriers to the polarization process, which has also been observed in other studies. 84 …”

“…83 The lower value of 3 N compared to 3 L is due to the contribution of free charge carriers to the polarization process, which has also been observed in other studies. 84 The value of the plasma frequency (u p ) is evaluated using the following Drude relation:…”

Analysis of various hole transport layers (HTLs) on the performance of CZTS- solar cell

“…The solar device was illuminated under AM 1.5 G and 1000 (Wm −2 ) light throughout the whole simulation for all potential structures [13,14] Here, the window layer, buffer layer, and absorber layers are ZnO: Al, ZnO & CdS, and CZTS respectively. The absorption coefficient spectrum as presented in figure 2 of the layers used in the proposed work has been determined from the measured transmission, reflection, or/and absorption spectra reported in the literatures [17][18][19][20][21][22][23] following the procedure reported elsewhere [24][25][26][27][28]. 3 presents the related performance analysis of various output parameters of HTLs.…”

Optimizing the structure and optoelectronic properties of cuprite thin films via a plasma focus device as a solar cell absorber layer

“…74 Other investigations have also observed a drop in the value of ε ∞ relative to ε L . 75,76 3.2.5. Dielectric parameters.…”
