Breakthrough Technique Opens Path to Flexible Solar Cells

摘要

Shigeru Niki, Deputy Director, and Shogo Ishizuka, Research Scientist, the Thin Film Compound Semiconductor Team, the Research Center for Photovoltaics of the National Institute of Advanced Industrial Science and Technology (AIST), in cooperation with Teijin Limited, have developed a technique for dramatically improving the energy-conversion efficiency of flexible photovoltaic cells that use non-silicon material composed of copper (Cu), indium (In), gallium (Ga) and selenium (Se). Using this technique, high-performance photovoltaic cells with a variety of flexible substrates, such as ceramics, metal foils, and polymers, can be fabricated.
