The multi-channel solar cell MPPT system is a powerful and comprehensive multi-channel solar cell and module stability test system tailored for perovskite solar cell researchers. It uses a BBA-level LED solar simulator as an aging light source, and can control the cell temperature and the environmental atmosphere (N2, dry air, constant temperature and humidity, etc.) in a variety of ways. It can perform long-term stability performance tests on multiple groups of cells at the same time. In addition to the traditional MPPT mode, it also adds constant voltage (such as open circuit voltage) and constant current aging (such as short circuit current) modes to increase the flexibility of stability research, and integrates powerful data analysis software to view and compare the performance indicators of different samples in real time.

In the fields of SC, PV, LEDs, MEMS devices, materials, etc., accurate measurement of surface step height and film thickness is of great value, and it is necessary to accurately and quickly measure and control various film step parameters.An important means to ensure material quality production efficiency.

Adopts contact surface topography measurement, which is a breakthrough development of traditional surface topography measurement. The minimum contact force can reach 1mg, and no special requirements for the reflective properties of the test surface, material type, and material hardness.
