Difference between heterojunction module and ordinary photovoltaic

There are differences in structure and material, principle, efficiency, cost, and application scope.

1, structure and material: Heterojunction modules are made of semiconductor materials by using a layered structure of several different materials, while ordinary photovoltaic is made of a single material, silicon.

2. Principle: Heterojunction module generates voltage and current by forming electronic energy level differences between different materials, while ordinary PV generates current through the interaction of photons with electrons in the material to excite and form carriers.

3. Efficiency: Heterojunction modules use a multilayer structure and an optimized combination of different materials to achieve higher efficiency, while ordinary PVs have lower efficiency.

4, cost: heterojunction module manufacturing process is complex, involving more materials and process steps, high cost. Ordinary PV, on the other hand, has a simpler, more mature manufacturing process and low cost.

5, application scope: heterojunction components are commonly used in high-performance photovoltaic applications, ordinary photovoltaic used for electric power applications and low-cost solar power system.
