PVeffecten

PVeffecten is a Dutch-language term used in scientific and engineering contexts to refer to phenomena related to photovoltaic (PV) effects in photoactive materials and devices. The term is not universally standardized and may be employed to describe a range of light-induced electrical responses observed in semiconductors, solar cells, and related optoelectronic structures.

The photovoltaic effect arises when photons with sufficient energy generate electron-hole pairs in a material, and an internal or built-in electric field separates these carriers to produce a current or voltage under illumination. Commonly studied quantities include the short-circuit current, open-circuit voltage, fill factor, and overall conversion efficiency. PVeffecten are influenced by light intensity and spectrum, temperature, device architecture, and material quality, as well as by interfaces and transport properties within the device.

In practice, researchers investigate PVeffecten using measurements such as current–voltage (IV) curves, external quantum efficiency (EQE), transient photovoltage, and impedance spectroscopy to understand recombination, charge transport, and interfacial effects. They are relevant across a range of PV technologies, including crystalline silicon, thin films (CdTe, CIGS), perovskites, and organic photovoltaics.

Beyond device physics, the term may appear in broader discussions about the role of PV technology in energy systems and policy, though this usage is less common in technical literature.
