Like the REEs, indium is another rare material that has seen its production somewhat monopolized by China in recent years. Indium is used in copper indium gallium selenide (CIGS) thin-film solar cells, but now IBM claims to have found a substitute approach... Made in IBM Labs: IBM Sets World Record by Creating High-Efficiency Solar Cell Made from Earth-Abundant Materials Breakthrough holds potential to deliver more energy at a fraction of the cost www-03.ibm.com ARMONK, N.Y. - 11 Feb 2010: IBM (NYSE: IBM) today announced it has built a solar cell -- where the key layer that absorbs most of the light for conversion into electricity, is made entirely of readily-available elements -- that set a new world record for efficiency and holds potential for enabling solar cell technology to produce more energy at a lower cost. Comprised of copper (Cu), tin (Sn), zinc (Zn), sulfur (S), and/or selenium (Se), the cell's power conversion demonstrates an efficiency of 9.6 percent -- 40 percent higher than the value previously attained for this set of materials.
