Better Thermoelectric Materials for the Weather

This entry was posted in weather and TE materials on July 08, 2016 by II-VI Marlow Industries

“If you don’t like the weather, just wait a minute” and “Texas has four seasons, drought, flood, blizzard and twister,” are colloquialisms that well characterize the state of Texas weather. 

As Texas covers a large geographical area, the variations in weather or climate can be significant.  What about the variations in weather across the United States, or around the world?  And how about global warming?  Is it real?  Is it something we need to try to affect?  What are the facts and whose facts are correct?  While we at II-VI Marlow may not have the answers to the global warming questions and/or be able to solve the global warming issue with thermoelectrics, we certainly can assist the scientists and climatologists that are working on this issue.

Weather and Climate Monitoring

The most efficient manner to analyze global weather and climate conditions is from space, where earth can be viewed over very large areas and patterns can be monitored.  Satellites orbiting the earth provide excellent platforms for sensors and instruments to view earth and collect data that relates current and future weather events.  Weather satellites can provide essential data for short and long term weather forecasting, storm tracking, climate monitoring, and predictive weather patterning.

One of the next generation weather satellites to be launched soon is JPSS-1. One instrument aboard the satellite is the advanced Ozone Mapping and Profiler Suite (OMPS). OMPS tracks the health of the ozone layer and measures the concentration of ozone in the Earth's atmosphere.  An II-VI Marlow designed, built and tested multi-stage thermoelectric (TE) module is used in the OMPS spectrometer application to cool the sensors and stabilizing the signal in order to insure the required performance.

TE Materials Research and Development

II-VI Marlow is able to provide the highest performing multi-stage TE modules because of TE material developments that have resulted in better TE performance at lower operating temperatures.  Shifting the optimum operating point “to the left” comes from an ongoing commitment to researching TE materials and making improvements that can be realized at both the module and system levels.  II-VI Marlow scientists and engineers are focused exclusively on material research and development that is continually evaluated and assessed for applicability to market demands and trends.

The Best Performing TE Module Designs

The range of TE materials provides options for optimizing each TE module design for the most efficient performance of the application operating condition.  II-VI Marlow products can respond to a greater range of application variations with more efficient solutions.  II-VI Marlow standard product multi-stage TE modules use these same temperature tuned materials.  The company’s commitment to materials research results in better performing TE modules for a wider range of customer applications.
