thermopile detectors have many thermocouples that are serially connected on a silicon substrate. The hot junction side (photosensitive area) is designed to be a thermally isolated structure, so heat generation caused by light absorption is kept to the membrane (thin film), increasing the temperature difference between the hot junction and cold junction. An infrared absorption film is attached ...
