Reconstructing Charge Collection Efficiency in Three Dimensions

Background The charge collection efficiency is a critical metric to evaluate the local electrical performance of optoelectronic devices. For example, defects show up as reduced charge collection efficiency. In two dimensions, the charge collection efficiency can, for example, be evaluated by the analysis of laser-beam induced current (LBIC), electron-beam...

Controlling Morphology and Porosity of Printed Reactive Inks for High-Precision Printing

Background The processes currently used to manufacture photovoltaic devices are suitable to achieve a minimum sustainable price, but low profit margins and high capital expenditures on equipment severely limit growth capacity, while also preventing introduction of newer innovative technologies into the market. Approximately 2 Mkg of silver ink and...

Conductive Adhesion Promoters for Reactive Inks

Background Conductive inks and pastes are a $2-billion-per-year industry that is ripe for a disruptive technology to broaden its application base. The silver pastes that currently dominate this market are suitable for photovoltaic applications, but their feature resolutions do not scale well below 50 μm, can damage delicate substrates, and require...
