Industry trends

In the report of the 20th National Congress, key words such as carbon peak carbon neutrality, sustainable development, and green development were mentioned many times. With the development of carbon peak and carbon neutrality, the application prospect of solar cells is broad. Solar cells are called photovoltaic cells in physics, and the core materials used in them are semiconductor materials, and the basis of battery energy conversion is the photovoltaic (photoelectric) effect. Usually after the solar cell is fabricated, it is tested and characterized to reflect the performance of the resulting cell.

Efficient collaboration

Optimizing the Solar Cell Testing Process

From research and development to production of solar cells, each link has different testing requirements, mainly including maximum current IMAX and voltage VMAX, open circuit voltage Voc, short circuit current lsc, fill factor FF and conversion efficiency η, etc.

The power supply used in the traditional l-V test can only output voltage or current, and cannot absorb energy as a load, while the digital source measure meter (SMU) is a precision instrument that can provide complete four-quadrant operation,

Combining the functions of current source, voltage source, ammeter, voltmeter and electronic load, it can independently measure the l-V characteristics of the device in all four measurement quadrants, greatly improving the test time and simplifying the overall test system design.
