HNEI has developed a state-of-the-art laboratory (see the Thin Films Lab ) that is used for the fabrication and characterization of thin film semiconductor devices for solar hydrogen production, thin film photovoltaics, and imaging applications. Recent projects included the development and demonstration of novel multijunction hybridphotoelectrodes (UH patented technology) for direct solar-to-hydrogen conversion utilizing low-cost metal-oxide and amorphous silicon thin-film materials, the development of high specific power Cu(In,Ga)Se2 thin film solar cells for satellite power and related applications, and the development of amorphous silicon alloy films for visible and near-IR digital imaging. These federally and industrially funded projects have near-term applications in both the commercial and military sectors.
HNEI’s research efforts have been particularly important in the ground-breaking developments concerning direct conversion of the sun’s energy into hydrogen and oxygen. These efforts were achieved through use of the HNEI-patented photoelectrochemical technology.
