Various embodiments may relate to an optoelectronic component apparatus, including a carrier, an optoelectronic component and a thermoelectric component on or above the carrier. The optoelectronic component has a planar, optically active region. The thermoelectric component has at least one thermoelectrically sensitive section, wherein the thermoelectrically sensitive section has a first electrical conductivity at a first temperature and a second electrical conductivity at a second temperature, and wherein the thermoelectrically sensitive section is thermally connected to the optoelectronic component in a planar fashion. The thermoelectric component is formed as a temperature sensor and/or thermogenerator.
