Question

Advantage of heterojunction over homojunction

Answer 1

heterojunction A heterojunction is a region of electrical contact between two different materials. .. Heterojunction devices have an inherent advantage over homojunction devices, which require materials that can be doped both p- and n-type.

Answer 2

Heterojunction and homojunction are the structure of photovoltaic solar cells.

Homojunctions:

Homojunction is the interface which can be found between layers of similar materials.

Heterojunctions:

It is the interface which can be found between two layers of dissimilar materials, crystalline semi-conductor or solid-state materials.

Advantage of heterojunction over homojunction:

• Solars cells
• Bipolar transistor
• Lasers
• Field effect transistors
