Abstract
The present invention concerns a method for the detection of sunlight with a detector arrangement that delivers an output signal as a function of incident sunlight. In the method a detector arrangement is deployed with an SiC-semiconductor detector, which is only sensitive to the UV-component of the incident sunlight. By the deployment of such a detector arrangement a disturbance of the sunlight detection by artificial light sources is to a large extent avoided, so that a more reliable detection of the sunlight is enabled.
Claims21
A method for the detection of sunlight, in which a detector arrangement is deployed, which is only sensitive to a UV-component of incident sunlight,
- comprising:
- deploying at least one SiC-semiconductor detector in the detector arrangement, in which a lower of two semiconductor regions form a pn-junction which has a dopant concentration of <1*1015 cm−3, and which has a thickness that is greater than 50% of the width of a space-charge zone in thermodynamic equilibrium, with the thickness not restricting the space-charge zone of this semiconductor region.
