摘要
Simulations indicate that efficiencies of 25-30% are attainable in-4-terminal, compound. semiconductor thin-film devices.. CIGS scan serve as the bottom cell, but a high band gap, transparent top cell with greater than 17% efficiency is needed. CdSe with an Eg of 1.7 eV and CdxZn1-xTe(CZT) that can also be. tuned to this range show high potential for this role. Using NUS structures we have - demonstrated the attainment of high electronic quality CdSe. External Jsc's of 14.7 mA/cm(2) have been on for attained without correction for substantial losses in the Cu contact. Similar progress has been made with CZT. High quality, single phase material-has been demonstrated.
