Summary:
Iowa State University researchers have developed a novel synthesis method to produce Nowotny-Juza semiconductors LiZnP and LiCdP.

Development Stage:

Description:
Nowotny-Juza phase materials are intermetallic crystal materials with potential for a variety of applications, and are of particular interest because their electronic structure makes them amenable to applications in solar cells (light to energy conversion), thermoelectrics (heat to energy conversion), optoelectronics (LEDs, laser diodes) and anode materials.  This technology is a novel method of preparing LiZnP and LiCdP materials using solution phase chemistry that results in rapid synthesis of the desired materials at moderate temperatures.  The resultant materials are phase pure, crystalline and have a size on the order of 20nm. In addition to the potential applications listed above, LiZnP is expected to be able to replace cadmium sulfide as the buffer material for Copper Indium Galium Selenide (CIGS) solar cells, reducing the environmental footprint of these thin-film photovoltaics.

Advantage:
• Novel solution phase chemistry
• Rapid reaction with high conversion rate at moderate temperatures
• Tunable particle sizes

Application:
LED Lighting, CIGS Solar Cells, Quantum Dots
