Designing a Robust Kelvin Probe Setup Optimized for Long-Term Surface Photovoltage Acquisition

We introduce a robust low-budget Kelvin probe design that is optimized for the long-term acquisition of surface photovoltage (SPV) data, especially developed for highly resistive systems, which exhibit—in contrast to conventional semiconductors—very slow photoinduced charge relax...
