Twenty-three percent of carbon emissions come from fossil fuels used in transportation. Electric vehicles are suggested as alternatives to fossil-fueled vehicles. Cars having vehicle integrated photovoltaics (VIPV) on the roof have recently been launched, aiming increase fuel efficiency and maximum mileage by supplying electricity when needed. VIPV needs be light terms efficiency. The use polymeric materials, made low-iron tempered glass front that contributes significantly module’s weight,...
The crystallization of hydrogenated amorphous silicon (a-Si:H) is essential for improving solar cell efficiency. In this study, we analyzed the a-Si:H via excimer laser annealing (ELA) and compared process with conventional thermal annealing. ELA prevents damage to substrate while maintaining melting point temperature. Here, used xenon monochloride (XeCl), krypton fluoride (KrF), deep ultra-violet (UV) lasers wavelengths 308, 248, 266 nm, respectively. Laser energy densities shot counts were...
Ultra-thin MoO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> is capable of exhibiting high work function (<; 6 eV), large band gaps 3 eV) are benefiting for surface passivation and hole selectivity layer in silicon solar cells instead the doped layers due to parasitic absorption. Importantly, electronic structure by oxygen dilution during evaporation have influence hence reduce injection. XPS study confirmed chemical composition...
An ultra thin surface passivation layer is essential to reduce the recombination and enhance open circuit voltage for high efficiency crystalline silicon (c-Si) solar cells. In that, we developed charge injection controllable films of SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">X</sub> SiN layers by PECVD boron emitter c-Si surface. The refractive index /SiN stack was optimized varying SiH...
HIT (heterojunction with intrinsic thin-layer) solar cells are in the spotlight as ultra-high efficiency cells. While an a-Si: H (i) (intrinsic hydrogenated amorphous silicon) layer is important for high quality passivation layers, TCO (transparent conductive oxide) has also become important. This paper describes changes properties of ITO (indium tin used a because its transmittance and conductivity at thin thickness. On other hand, relatively free carrier concentration low mobility...
