SSPG-100 is our standard tool for measuring the minority carrier diffusion length for thin film semicondconductor materials

• The SSPG-100 has a substrate holder exposed to air and there is no heating
• The SSPG-100 is mainly used for inorganic materials such as silicon based thin films (a-Si, µc-Si, poly-Si) or any other materials (a-SiGe, III-V, ...)

SSPG-230 is more suitable for organic semiconductors and to perovskite materials

• The SSPG-230 has a substrate holder sealed in a separate chamber and can be heated up to 200 °C
• The substrate chamber can be either pumped down or filled with inert gas
• The SSPG-230 has been applied to BHJ materials such as (P3HT:PCBM) , etc and to perovskite
