1、Transparent conductive layer of solar cell

　　‌● Core components of thin-film solar cells

　　As a transparent electrode layer, the ITO thin film is coated on the surface of solar cells. ITO film can help achieve high efficient absorption of light energy and current transmission, reducing energy losses because of its low resistivity (ranging from 10⁻⁴ to 10⁻³ Ω·cm) and high light transmittance (>85%), Its cubic crystal system structure (a solid solution of In₂O₃ and SnO₂) optimizes the carrier mobility (15-50 cm²/V·s) and enhances the photoelectric conversion efficiency.

　　‌● Performance optimization of heterojunction cells

　　In silicon-based heterojunction (HJT) solar cells, the ITO thin film balances the electrical conductivity and light transmittance by adjusting the doping ratio (In₂O₃₂≈9:1), which can reduce the contact resistance and enable the cell efficiency to exceed 25%.

2、Application of new photovoltaic technologies

　　‌● Carrier transport layer in perovskite cells

　　As a transparent conductive substrate for perovskite solar cells, the ITO thin film takes advantage of its wide bandgap (3.6-4.0 eV) property to reduce light absorption losses, and enhances the interfacial stability between the perovskite layer and the electrode through surface modification.

　　‌● Support material for flexible photovoltaic devices

　　The mechanical flexibility of the ITO thin film makes it suitable for foldable solar cells. Combined with a low-temperature deposition process (such as magnetron sputtering), it enables the realization of lightweight and wearable energy devices on flexible substrates (PET/PEN).

3、Other battery-related applications

　　‌● Photoelectrocatalytic hydrogen production

　　The catalytic activity of indium oxide (In₂O₃) is used in the system of hydrogen production from water photolysis. As a catalyst carrier, the ITO thin film enhances the density of reactive active sites through surface defect engineering.

　　‌● Transparent electrodes for energy storage devices

　　In energy storage devices such as transparent supercapacitors, the ITO thin film as a transparent current collector can balance the requirements of energy storage and optical transparency.
