This article reports the thermoelectric‐based solar energy harvesting. The effect of candle soot (CS) coating on solar energy harvesting potential of thermoelectric modules is studied. To compare the performance, uncoated/coated modules are exposed to solar radiations (through Fresnel lens) and the other side is kept at lower temperature using continuous water flow. Substantial enhancements in electrical outputs are observed due to CS coating on the upper surface of the thermoelectric module. The open‐circuit voltage and short‐circuit current across coated module improve more than six times in comparison to the uncoated module with maximum voltage and current reaching up to 1.5 V and 14 mA. Similarly, the generator can deliver a maximum power of 10 mW across a resistance of 50 Ω. Results indicate that the CS coating is an effective technique to improve the performance of thermoelectric materials for running sensors and other low‐power electronic devices.

使用涂有蜡烛煤灰的热电材料进行太阳能收集。

本文报道了基于热电的太阳能收集。研究了蜡烛烟灰（CS）涂层对热电组件太阳能收集潜力的影响。为了比较性能，未镀膜/镀膜的模块（通过菲涅耳透镜）暴露在太阳辐射下，另一侧使用连续的水流保持较低的温度。由于热电模块上表面的CS涂层，可以观察到电输出的显着提高。与未涂层的模块相比，涂层模块上的开路电压和短路电流提高了六倍以上，最大电压和电流高达1.5 V和14 mA。同样，发生器可在50Ω的电阻上提供10 mW的最大功率。
