Development of II-VI ternary alloys for CdTe-based solar cells
CdTe has emerged as the leading commercial thin film photovoltaic technology. Recent advancements in photoconversion efficiency were achieved through the introduction of alloyed CdSeyTe1-y (CST) absorber, as well as replacement of conventional CdS window layer with more transparent alternatives such as MgxZn1-xO (MZO). These II-VI ternary alloys offer a wide range flexibility of adjusting several important parameters of the CdTe-based solar cells, such as band gap and conduction band alignment. The focus of this thesis can be divided into two parts: development of Cd1-xZnxTe (CZT) absorbers and ...
