Thermocouple for obtaining electrical energy and arrangement with a thermocouple and a photoelement

摘要

The invention relates to a thermoelement for obtaining electric energy, comprising two different thermoelectric materials (2, 3), which are electroconductively interconnected in a contact area (1). In existing thermoelements, the electrical resistance of the thermoelectric materials (2, 3) counteracts the thermoelectric voltage, said resistance being high for thermoelectric materials (2, 3) with high thermoelectric voltage. In order to improve the effectiveness of the thermoelement, the invention provides that both thermoelectric materials (2, 3) are configured as limbs (2, 3) outside the contact area (1), said limbs being insulated from each other and both thermoelectric materials being fitted with a good electric conductor (7) which is configured in both the contact area (1) and the limb area (2, 3), in addition to being connected to both thermoelectric materials (2, 3) in a substantially electrically conductive manner along its entire length and not, however, being connected at any point to the other conductor (7).
