Key Features:

1. Thermoelectric Conversion:
   • Converts heat directly into electricity using thermoelectric materials. When one side of the thermoelectric module is exposed to heat (high temperature), while the other side is kept cooler, a voltage is generated across the module.
   • This is based on the Seebeck effect, where a temperature difference between two dissimilar conductors or semiconductors generates a potential difference (voltage).
2. Operating Temperature Range:
   • High Temperature Tolerance (150°C): The generator is specifically designed to operate in high-temperature environments, where the temperature on one side of the module can reach 150°C, making it suitable for industrial, automotive, and waste heat recovery applications.
   • It may be capable of withstanding even higher temperatures on the hot side with proper heat management, although 150°C is the rated operating temperature.
3. Module Size:
   • 40x40mm: The module has a square form factor with dimensions of 40mm x 40mm, making it compact and suitable for various applications where space is limited.
4. Power Output:
   • Power Generation: The output power of thermoelectric generators typically depends on the temperature difference between the hot and cold sides, the material properties, and the size of the module. At 150°C on the hot side, the TEG can generate a few watts of power, typically in the range of 1W to 5W depending on the specific module’s efficiency and the temperature difference.
   • Output Voltage: The output voltage is typically low, often around 2-3V depending on the temperature gradient, which can then be regulated or stepped up for use with specific devices.
5. Efficiency:
   • Thermoelectric generators are generally not very efficient compared to other methods of power generation (like turbines or engines). The efficiency is usually low, often around 5%-10% of the heat energy being converted into electrical energy. However, they have the advantage of being solid-state devices with no moving parts, making them reliable and durable.
   • Figure of Merit (ZT): The efficiency is related to the material’s figure of merit (ZT), which depends on the thermoelectric properties of the material used (such as bismuth telluride or other advanced semiconductor alloys).
6. Durability and Longevity:
   • Solid-State Design: Thermoelectric generators have no moving parts, making them highly durable and capable of operating in harsh environments with minimal maintenance.
   • They are ideal for applications where reliability and longevity are essential.
7. Heat Dissipation:
   • The efficiency of thermoelectric generators depends significantly on maintaining a large temperature gradient between the hot and cold sides.
   • The cold side typically needs to be kept cooler (often with a heat sink or cooling mechanism) to maximize the temperature difference and, thus, the power output.
8. Compact and Lightweight:
   • The 40x40mm size makes the TEG module compact and lightweight, suitable for embedded applications where space is constrained, such as in portable power devices, automotive exhaust systems, and industrial waste heat recovery setups.
9. Low Voltage and Current Output:
   • The power output from thermoelectric generators is generally low voltage (2-5V) and low current. As a result, the electrical output may need to be regulated, boosted, or stored to be useful for specific devices or systems (e.g., using a DC-DC converter, charging a battery, or driving low-power electronics).
