Radiation-Resilience Layered Structure for Direct Energy Conversion Devices (Radwich)
Invention Description Reliable power generation in extreme or remote environments is challenging, especially where conventional energy sources or battery replacement are impractical. Devices exposed to radiation or harsh operating conditions often experience material degradation that reduces efficiency and operational lifespan over time. Existing compact...

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...
