The crystalline silicon (c-Si) based photovoltaic (PV) technology is most dominated among
other PV technologies. The world record highest efficiency of 26.7% and 26.1% on n & p …

In this study, we report for the first time that the addition of an intrinsic layer to the a-Si: H p–i–
n solar cell structure greatly enhances the conversion efficiency. The a-Si: H p–i–n solar …

Hydrogenated amorphous silicon (a-Si: H) materials have received a great deal of attention
for their potential to make inexpensive solar cells. In this work, we report that the effect of …

In view of the grossly different chemical reaction behaviors of the precursors generated from
two different very commonly used source gases, eg, SiH 4 and GeH 4, development of nc-Si …

Spectroscopic ellipsometry (SE) is a sophisticated technique to find the optical constants,
bandgap and microstructure of thin layer. SE is used to study the microstructure evolution in …

In this work, we perform a numerical modeling of silicon thin film deposition for a
photovoltaic application in a capacitive coupled plasma reactor (CCP) using RF excitation …

Different processes are used to improve the deposition of a nanocrystalline silicon layer to
enhance optical absorption in different devices. The difficulty encountered lies in the …

In the present work, three series of hydrogenated silicon thin films were prepared by
radiofrequency magnetron sputtering method at low temperature, various deposition …

This work initiates a series of reports aimed at a construction of rugate optical filters based
on silicon rich materials of alternating gradients of refractive index n with the help of plasma …

Using plasma-enhanced chemical vapor deposition (PECVD), a mixed gas of silane (SiH 4)
and methane (CH 4) was diluted with hydrogen (H 2) to produce thin films of silicon …
