补充资料:半导体能量转换器件
半导体能量转换器件 semiconductor energy converter 将一种形式的能量转换成另一种形式的能量的半导体器件。主要是指作为能源的能量转换器件,如太阳电池、温差发电机、温差电致冷器等。这类器件的主要特点是体积小、重量轻、无噪声、无污染。太阳电池利用半导体光生伏特效应,将太阳能直接转换成电能。太阳电池主要应用在航天领域,在微小型计算器中也被广泛采用。温差发电机利用半导体温差电效应(半导体的两端如果温度不同就会产生温差电动势,又称赛贝克效应),将热能转换成电能。温差发电可以利用各种能源,包括固、液、气态燃料,太阳能、核能、地热,以及各种设备的废热、余热等,因而特别适用于军事、勘探和边远地区等的小功率发电和星际航行。温差电致冷器利用珀耳帖效应(两种不同金属连接起来并通以电流时,一接头吸热,另一接头放热)达到致冷目的。广泛用于各种仪器仪表和医疗器械制冷中。除此之外,半导体能量转换器还包括作为信息转换的能量转换器件,如传感器、光电器件等。 |
