The University of Texas at El Paso (UTEP) and the Center for Integrated Technologies (CINT) in collaboration with Sandia National Laboratories are working together to develop new class of photovoltaics to achieve high performance on CdTe based solar cells.
The group uses techniques from nanoheterohepitaxy to create defect-free CdTe devices to obtain higher efficiencies and for a controlled study of these devices while maintaining the cost advantages of thin film technology. Using selective growth techniques, small nearly defect free islands of CdTe are produced on CdS substrates. With appropriately small islands, interfacial dislocations can be eliminated to produce higher open-circuit voltage cells. The successful candidate will work in all phases of this project including clean room fabrication of the devices, electro-optical characterization, and physical characterization using TEM and SEM. Candidate will supervise students and is expected to publish results in peer reviewed journals. The primary place of work will be at CINT in Albuquerque, New Mexico but the work will be coordinated between Sandia, CINT, and UTEP. Periodic visits to UTEP will take place.
Other related functions as assigned.
The candidate must have a Ph.D. in Electrical Engineering, Materials, or related field and be proficient in the English language to include reading, writing and speaking.
