Development of in-situ doped poly-SiOx passivating contacts for high-efficiency solar cells

Carrier-selective passivating contacts (CSPCs) is now a popular contact structure that effectively passivates the crystalline silicon (c-Si) surface as well as selectively extracts the specific type of charge carrier (electrons or holes). In this thesis work, we developed the CSPCs based on oxygen-alloyed polycrystalline silicon (poly-SiOx)...

Suppressing the Photocatalytic Activity of TiO2 Nanoparticles by Extremely Thin Al2O3 Films Grown by Gas-Phase Deposition at Ambient Conditions

This work investigated the suppression of photocatalytic activity of titanium dioxide (TiO2) pigment powders by extremely thin aluminum oxide (Al2O3) films deposited via an atomic-layer-deposition-type process using trimethylaluminum (TMA) and H2O as precursors. The deposition was performed on multiple grams of TiO2 powder at room temperature...

Scalable and Environmentally Benign Process for Smart Textile Nanofinishing

A major challenge in nanotechnology is that of determining how to introduce green and sustainable principles when assembling individual nanoscale elements to create working devices. For instance, textile nanofinishing is restricted by the many constraints of traditional pad-dry-cure processes, such as the use of costly chemical precursors to...
