About Solar temperature difference power generation equipment
Thermoelectric materials generate power directly from the heat by converting temperature differences into electric voltage. These materials must have both high electrical conductivity (σ) and low thermal conductivity (κ) to be good thermoelectric materials.
A thermoelectric generator (TEG), also called a Seebeck generator, is adevice that converts(driven bydifferences) directly into through a phenomenon called the.
The typical efficiency of TEGs is around 5–8%, although it can be higher. Older devices used bimetallic junctions and were bulky. More recent devices use highly doped semiconductors made from(Bi2Te3),(PbTe),calcium manganese.
Only a few known materials to date are identified as thermoelectric materials. Most thermoelectric materials today have a zT, the figure of merit, value of around 1, such as in(Bi2Te3) at room temperature and(PbTe) at 500–700 K. However, in.
Besides low efficiency and relatively high cost, practical problems exist in using thermoelectric devices in certain types of applications resulting from a relatively high electrical output resistance, which increases self-heating, and a relatively low thermal conductivity.
