Solar cell testing focuses on the device's overall current–voltage traits (efficiency, fill factor); IPCE testing focuses on external quantum efficiency at each wavelength, answering "which band helps most." Complementary, they together characterize photoelectric conversion performance.
The PL-IV Solar Cell Test System targets standard IV-curve testing, giving short-circuit current, open-circuit voltage, fill factor, and power conversion efficiency—the basic health check of device performance.
The PL-IPCE Solar Cell Test System gives the external quantum efficiency spectrum, locating the material's light-absorption and charge-collection shortfalls to guide band and interface optimization—a mechanism-level characterization tool.
| System | Core Output | Best For |
|---|---|---|
| PL-IV Solar Cell Test System | IV curve, efficiency, FF, V_oc | Overall device performance |
| PL-IPCE Solar Cell Test System | EQE spectrum vs wavelength | Band/interface diagnosis |
