The anti-reflection film can improve the light transmittance and electrical conductivity of the solar cell, thereby ensuring the practicability of the solar cells. Therefore, it is very important to prepare ITO films with high conductivity and high permeability. A high-quality ITO film must have suitable electrical and optical properties in order to maximize the efficiency of photovoltaic cells. The spectrophotometer owned by "Millennial Solar" can be used to detect the ITO thin film of solar cells, and indirectly improve the light transmittance and conductivity of solar cells, thereby ensuring the product quality of solar cells, which provides strong support for the efficiency of solar cells.

Take You to Understand the Millennial Spectrophotometer

The Millennial spectrophotometer adopts a unique dual-beam optical design, which can perfectly correct the absorbance changes of different ITO films, so as to perform sample measurement stably. Its test principle is to use the material to selectively absorb light of a certain wavelength to identify the material or determine its content. Millennial spectrophotometers allow qualitative analysis and quantitative analysis of substances based on comparisons of absorbance with standards of known concentration, allowing the calculation of large volumes of reliable data.

Massive Advantages, Explained One By One 

The dual-detector system of the Millennial spectrophotometer can obtain excellent test performance in the entire spectral range, and cover the entire ultraviolet-visible-near-infrared band, and the wavelength range can reach 190nm-2800nm. And the provided dual light source system can make the pre-focused light source switch quickly, so as to ensure the normal working time to the greatest extent.

The double grating optical structure adopted by Millennial spectrophotometer can effectively reduce stray light and achieve high-precision measurement.

At the same time, the most advanced four-zone sectoral signal collection chopper is used to ensure the most accurate sample and reference signals every time.

And the diameter of the integrating sphere can reach 100mm, so that the solar cells will not turn yellow after long-term use, and the optical performance is stable.

Signal processing techniques employed in Millennial spectrophotometer minimizes errors caused by detector switching.

Meet the unique needs of customers

ITO thin film is a transparent conductive layer, which can be used as a light-transmitting layer in solar cells, and can also be used as an electrode. Therefore, the ITO thin film must have appropriate electrical and optical properties, and the electrical and optical properties are interrelated, and must be optimized at the same time to maximize the efficiency of solar cells.

Schematic diagram of transmittance and reflectance

Millennial spectrophotometer is mainly used to measure the reflectivity and transmittance of ITO thin film and amorphous silicon, microcrystalline silicon and other thin film materials in the photovoltaic field, and it is mainly used to measure the conductivity and light transmittance of ITO thin film. It can meet the needs of collecting reflectance and transmittance data of ITO thin films in the full band of 300~1200nm, and is widely used in the photovoltaic industry.

Coating anti-reflection film can further help solar cells absorb light, thereby improving the light transmittance and conductivity of solar cells, and ensuring the performance of solar cells. Spectrophotometer developed by "Millennial Solar" helps companies control the production process, indirectly improves the photoelectric conversion rate of commercial finished cells, and provides satisfactory services for battery manufacturers!
