Do you need separation strength, kinetic speed, or device efficiency? Different goals call for different instruments. Define the question first, then choose the tool.
| Research Goal | Recommended | Information Provided |
|---|---|---|
| Steady-state separation & band gap | PL-SPV/IPCE1000 Steady-State Surface Photovoltage Spectrometer | Separation strength, flat band, IPCE |
| Charge dynamics | PL-TPV Transient Surface Photovoltage Spectrometer | Charge lifetime, transfer rate |
| Spectroscopic photoelectric response | PL-PES Spectroscopic Photoelectric System | Broadband photoelectric spectrum |
| Compact photoelectric screening | PL-MINI PES Photoelectric Test System | Rapid photoelectric measurement |
| External quantum efficiency | PL-IPCE Solar Cell Test System | Wavelength-resolved efficiency |
For intrinsic mechanism use SPV + TPV; for device/efficiency use PES + IPCE; finally return to real-activity verification with the PLR-GSPR Atmospheric-Pressure Gas-Solid Photocatalytic Reaction System or the PCX-50C Discover Multi-Channel Photocatalytic Reaction System.
Don't buy the most complete configuration upfront; first pick one or two instruments by your current project, and add more as the bottleneck shifts—avoiding idle instrument time.

Define your research goal first—separation strength, kinetics, or efficiency—then the right instrument follows.
It maps research goals (steady-state, dynamics, spectrum, screening, EQE) to the recommended PL instrument and the information it provides.
SPV+TPV for intrinsic mechanism, PES+IPCE for device efficiency, then verify with PLR-GSPR or PCX-50C for real activity.
