Popis: Anisotype heterojunctions of p-GaAs/n-Cd1-xZnxS1-yTey have been fabricated by preparing n-type Cd1-xZnxS1-yTey thin films onto p-GaAs single crystal wafers using an electrochemical deposition method. The voltammetric behavior of the Cd1-xZnxS1-yTey thin films on GaAs substrates from aqueous solutions was studied. Electrical and photoelectrical properties of heterojunctions were studied depending on the Cd1-xZnxS1-yTey films composition (x = 0.1 ÷ 0.8; y = 0.2; 0.4; 0.9) and heat treatment (HT) regime in argon atmosphere (100–450 °С during 3–16 min). Under AM1.5 conditions, the open-circuit voltage, short-circuit current, fill factor, and efficiency of our best cell, was Voc = 584 mV, Jsc = 14.54 mA/cm2, FF = 0.6, and η = 6.7%, respectively.
