Solar cells and photocatalysts utilize type-II PN junctions to effectively segregate charge carriers generated by external stimuli. The assessment of material band alignment involves a series of steps: Initially, UV spectroscopy is employed to determine the materials' band gap through Tauc plot analysis. Subsequently, by utilizing Ultraviolet Photoelectron Spectroscopy (UPS), a precise estimation of the materials' band alignment can be inferred.

Should the potential of the band be lower or higher than Bi2WO6? I use B4C but the removal efficiency is lower than Bi2WO6

Şükrü Aktaş

pn junction malzemeler p-tipi veya n-tipi ile birbirine bağlanabilir. Malzemenin p-tipi veya n-tipi olması onun özelliğine bağlıdır. Malzemenin verimliliği ise yük akışı sırasında değişken olduğu için (p-n, n-p) verim ana malzemeden biraz düşük olur.
