制备了用于热光电复合太阳能发电的薄膜热电组件。采用射频磁控溅射法制备了Bi0.5Sb1.5Te3（p型）和Bi2Te2.7Se0.3（n型）热电薄膜，并利用剥离技术对薄膜进行了图案化，制备了平面型热电模块。该混合模块由薄膜热电模块、光伏模块、热镜和近红外（NIR）聚焦透镜组成。使用热镜将不有助于光伏转换的NIR光与太阳光分离。当NIR光通过透镜聚焦到热电模块的热侧上时，由薄膜热电发生器产生的开路电压为78 mV。与单独使用光伏组件相比，热光伏混合发电机的总开路电压提高了1.3%。(C)2012日本应用物理学会
We fabricated thin-film thermoelectric modules for thermal-photovoltaic hybrid solar generator. Bi0.5Sb1.5Te3 (p-type) and Bi2Te2.7Se0.3 (n-type) thermoelectric thin films were deposited by radio-frequency magnetron sputtering method and patterned to form plane-type thermoelectric modules using lift-off technique. The hybrid module consisted of the thin-film thermoelectric module, a photovoltaic module, a hot mirror, and a near-infrared (NIR) focusing lens. NIR light, which does not contribute to photovoltaic conversion, was separated from solar light using the hot mirror. When the NIR light was focused onto the hot side of the thermoelectric module by the lens, the open voltage generated by the thin-film thermoelectric generator was 78 mV. The total open voltage of the thermal-photovoltaic hybrid generator increased by 1.3% compared to that of the photovoltaic module alone. (C) 2012 The Japan Society of Applied Physics
