Understanding the Role of CdTe in Polycrystalline CdSe<sub>x</sub>Te<sub>1–x</sub>/CdTe‐Graded Bilayer Photovoltaic Devices

Grading of bandgap by alloying CdTe with selenium to form a CdSexTe1–x/CdTe- graded bilayer device has led to a device efficiency over 19%. A CdSexTe1–x absorber would increase the short-circuit current due to its lower bandgap but at the expense of open-circuit voltage. It has been demonstrated tha...
