Innovative Elastic Thin-Film Solar Cell Structures

Oligo- and polythiophene/ZnO hybrid nanowire solar cells.

We demonstrate the basic operation of an organic/inorganic hybrid single nanowire solar cell. End-functionalized oligo- and polythiophenes were grafted onto ZnO nanowires to produce p-n heterojunction nanowires. The hybrid nanostructures were characterized via absorption and electron microscopy to determine the optoelectronic properties and to probe the morphology at the organic/inorganic inter...

Microfabrication of Thin-Film Solar Cell Contacts Through Photolithography

Solar energy has emerged as an inexpensive and powerful means for clean energy production and draws much research interest. In particular, thinfilm solar cells often rely on the use of permanent shadow masks to pattern their front metal contacts for energy transport. However, these machined masks are not adjustable, and currently limit the scope of experimentation. In addition, the essence of f...

Heteroepitaxial Cu2O thin film solar cell on metallic substrates

Heteroepitaxial, single-crystal-like Cu2O films on inexpensive, flexible, metallic substrates can potentially be used as absorber layers for fabrication of low-cost, high-performance, non-toxic, earth-abundant solar cells. Here, we report epitaxial growth of Cu2O films on low cost, flexible, textured metallic substrates. Cu2O films were deposited on the metallic templates via pulsed laser depos...

Preparation and Characterization of Electrocatalyst Nanoparticles for Direct Methanol Fuel Cell Applications Using β-D-glucose as Protection Agent

In this study, the activity, stability and performance of carbon supported platinum (Pt/C) electrocatalyst in cathode and carbon supported Pt and ruthenium (PtRu/C) electrocatalyst in anode of direct methanol fuel cell (DMFC) were studied. The Pt/C and PtRu/C electrocatalysts were prepared by impregnation reduction method. The β-D-glucose was used as protection agent to reduce the particle size...
