Most of the high-efficiency c-Si solar cells are based on dielectric films that electrically passivate c-Si surface and must keep their passivation properties after metal deposition on top of them. This work studies the ...

Impedance spectroscopy differences between colloidal 295-nm silica and 300-nm polystyrene nanoparticles in deionized water are analyzed in this work. Using two different two-electrode measurement setups, designed for this ...

In crystalline silicon (c-Si) solar cell field, an intensive effort is being paid to reduce the quantity of silicon material used in each cell in order to minimize its costs. With the reduction of wafer thickness, light ...

An electrospray technique has been used to deposit SiO2 nanoparticles as insulator layer of a metal-insulator-metal device. Impedance spectroscopy measurements show that a 4.4 factor increase in capacitance is achieved ...

Nanostructuring materials such as silicon provides a good technology to fabricate optical and sensing devices. The possibility to fill the pores or channels with different material opens the way to new applications. In ...

In this paper we introduce the electrospray technique as a suitable method to create SiO2 3D ordered nanostructures. We describe the experimental procedure and deposition parameters required. We have found that the use of ...

In this work, a novel mixture of ionic liquid gel polymer electrolyte (ILGPE), containing 1-butyl-3-methylimidazolium bromide, ammonium acetate and poly(vinyl alcohol), with Si@C and SiO2 embedded nanoparticles is fabricated. ...
