'On Chip' Smart Sensor Array and Control Teleplatform for Thermophotovoltaic Cell Manufacturing Applications

60731 Thermophotovoltaic (TPV) cells offer many opportunities as an alternate energy source. However, problems in TPV cell characterization, needed for manufacturing process control have an adverse impact on efficient cell manufacturing and yields. This project will develop an `On Chip¿ smart sensor array to characterize TPV cell parameters such as temperature gradients, poly metal sheet resistively, and thin film substrate thickness. Using a custom smart sensor array and an application specific ¿Device Characterization Platform,¿ accurate `On Cell¿ measurements and control via wireless tele-platform feedback system will be engineered. In Phase I, the `On Chip¿ sensor array concept was verified through virtual software system analysis. An application-specific ¿Device Characterization Platform¿ was built and its rudimentary interface circuits were tested for integrity, functionality, and performance. In Phase II, the actual TPV cell with `On Chip¿ embedded smart sensor array will be fabricated. Prototype TPV cell units will be used on the TPV ¿Device Characterization Platform¿ to collect temperature gradient data. Commercial Applications And Other Benefits as described by the awardee: The technology should result in reduced TPV cell costs and improved energy conversion. Applications that have waste heat and require noiseless and emission free compact electrical generators should be candidate markets for this TPV technology.
