Whether it is the annealing process or the thinning process of solar cells, they need to be scientifically tested through high-precision testing equipment after the completion of production. For this reason, Millennial Solar has produced instruments that can efficiently evaluate and characterize the performance and quality of solar cells after these processes. Spectrophotometer, this equipment can complete the detection of many performance parameters such as resistivity and conductivity of many thin film materials such as ITO films, and can perform parameter characterization through control data processing software that can clearly and objectively reflect solar cells, thereby helping photovoltaic enterprise users and their solar cell manufacturers produce efficiently.

Spectrophotometer

The main reason why Spectrophotometer is widely favored by photovoltaic enterprise users is its convenience of functions and considerable advantages. Different from other similar equipment, the Spectrophotometer allows users to detect the desired film performance parameters in a short period of time, analyze regional film performance parameters through detailed classification, and discover solar cell performance problems through data comparison.

The Spectrophotometer adopts a unique dual-beam optical design that can perfectly correct the absorbance changes of different ITO films, allowing for stable sample measurement.

● Adopt dual light source and dual detector design

●Super large wavelength range 190-2800nm

●Double grating optical structure effectively reduces stray light

● Integrating sphere diameter can reach 100mm

● No yellowing and stable optical properties after long-term use

● It can minimize the error caused by detector switching

Control data processing software - powerful functions

Spectrophotometer adopts a new control data processing software, and adds a data table and list display function of data processing results in the software. Solar cell manufacturers and their photovoltaic enterprise users can clearly and objectively understand the properties of thin film materials through this function, such as transmittance, conductivity, etc.

The software is very convenient to operate. You can characterize the desired performance parameters of thin film materials such as ITO films in just four steps. First, you only need to set the conditions according to the purpose of analysis. After setting, you can save the detailed information and data of the sample to be tested. After the setting is completed, you can perform baseline scan and sample scan with one click. Moreover, the software supports full Chinese operation, the functions are simple and easy to use, and the professional testing software is equipped with functions such as boundary data import, fast and convenient storage, and flexible operation.

Provide precise electrical testing of thin films

The Spectrophotometer is similar to the Four-Point Probe Tester, Stylus Profiler and other equipment produced by Millennial Solar. This type of equipment is used for precise testing of many thin film materials such as ITO films in solar cells. The difference is that after the production process is completed, it is impossible to conduct comprehensive performance testing of the deposited thin film materials by using only one piece of equipment to detect them.

In order to make the detection equipment perform its duties and play its maximum role in the production process, Millennial Solar produced the Spectrophotometer, which uses ultraviolet to near-infrared region measurement to accurately detect and characterize the transmission of thin film materials deposited on the surface of solar cells. efficiency and conductivity, and supports diverse detection of liquids and solids.

Spectrophotometer can be used not only to detect ITO films, but also to detect many thin film materials such as crystalline silicon films. By collecting the reflectivity, transmittance and other performance parameters of these thin film materials, it can provide solar cell manufacturers with accurate data to help them conduct solar cell testing. Adjustments and optimizations!

In the future, Millennial Solar will continue to produce high-quality solar cell and module testing equipment, and try its best to promote the development of the photovoltaic industry towards a better tomorrow!
