Abstract

We developed the optical fiber built-in type Kelvin probe, which was combined with the previously developed system. This system can be applied to measure band diagram included fermi level of organic/inorganic semiconductor, and photovoltage. This system is also applied to the wide range environment from ultra-high vacuum to the atmosphere. We demonstrated photovoltage measurement of polycrystalline Si solar cell. Obtained photovoltage was increasing with increasing photon power. As photovoltage is associated with open-circuit voltage, the obtained results are consistent with its trend. This system has a very wide range of applications ranging from band gap science and solar cell evaluation.
