Cited 1900 times (May 2019) -  Journal: Advanced Energy Materials Link: Device Characteristics of CZTSSe Thin-Film Solar Cells with 12.6% Efficiency Challenge: Decrease Voc deficit of current CZTSSe (1.13 eV) solar cells. The reported device has 12.6 % efficiency with  500 mV of Voc from a maximum of 820 mV calculated by SQ analysis. Therefore if Voc is enhanced the device would get better. But to achieve this enhancement we should…

Title: Identifying the Real Minority Carrier Lifetime in Nonideal Semiconductors: A Case Study of Kesterite Materials Authors: Charles J. Hages,* Alex Redinger, Sergiu Levcenko, Hannes Hempel, Mark J. Koeper, Rakesh Agrawal, Dieter Greiner, Christian A. Kaufmann, and Thomas Unold* Link: Adv. Energy Mater. 2017, 1700167 (Cited by 16) Abstract: Time‐resolved photoluminescence (TRPL) is a powerful characterization technique to study carrier dynamics and quantify absorber quality in semiconductors. The minority carrier lifetime, which is critically…
