Co-Extrusion Printing for Low Cost and High Performance Energy Devices

Shrader E., Cobb C., PARC, a Xerox company, US

The method of co-extrusion of dissimilar materials has been developed at the PARC, a Xerox Company, to successfully produce high aspect ratio structures for solar cell gridlines. In the solar application, the process is stable [...]

Innovative Technology for Algae Dewatering

Hsieh H.B., Chang N., Melde K., Kole A., PARC, a Xerox company, US

This paper describes a novel technology for dewatering of algae for biofuel production and other applications. This hydrodynamic separation (HDS) technology uses customized fluid flow patterns in a curved channel to focus suspended particles into [...]

Interactions of Rocks with Supercritical CO2 and Water in Enhanced Geothermal Systems and Beyond

Petro M., PARC, a Xerox company, US

There is an abundance of heat but lack of fluids underground. Current drilling and fracturing technologies can provide necessary access to the hot rocks, creating so-called Enhanced Geothermal Systems (EGS). Despite the 100-fold increase in [...]

The identification of recombination centers in organic solar cells

Street R.A., Krakaris A., PARC, a Xerox company, US

To achieve high efficiency bulk heterojunction organic solar cells, it is necessary to identify and minimize the recombination centers that limit the performance. There is growing evidence that the dominant recombination is through trap states [...]

Improvement of Silicon Solar Cell Metallization with Printed Metal Nanoparticle Inks

Xu B., Limb S., Rodkin A., Shrader E., Garner S., PARC, a Xerox company, US

The process and quality of metallization greatly affects the performance and cost of solar cells. Screen printing of silver paste and fire-through of the silicon nitride antireflection layer is the most widely used method for [...]
