Dr. Haber’s research interests are centered on developing methods in Inorganic Materials Chemistry and in Combinatorial and High-Throughput Materials Science, especially as applied to materials and devices for solar-energy conversion.  Of particular interest is the synthesis of nanomaterials and semiconductor thin films using chemical and electrochemical syntheses, physical vapor deposition, chemical vapor deposition, and reactive annealing processes.

Within JCAP, Dr. Haber’s research focus surrounds the application of high-throughput methods to integrate promising lead materials into functional assemblies, such as integration of electrocatalyst libraries with light absorbers to produce functional photoanode and photocathode assemblies.  He continues to develop new and improved precursor ink solutions and reactive thermal processing strategies to enable the synthesis of increasingly compositionally diverse, discrete composition material libraries via ink-jet printing and post-deposition reactive thermal processing.  He coordinates specific combinatorial research efforts, including follow-on studies of promising lead materials in order to facilitate transition of discoveries to directed research projects and to scaleup integrated components.
