Researchers have successfully produced with a high degree of crystallinity of platinum-rhodium thermocouple

Platinum rhodium thermocouple battery is considered to be a promising renewable energy industry innovation seeds, because it is a flexible, lightweight, economic and efficient green equipment.

however, compared with the traditional silicon platinum-rhodium thermocouple battery, platinum, rhodium thermocouple battery energy conversion efficiency is low.

in semiconductor platinum-rhodium thermocouple battery, the light in two semiconductor layers in the battery & other; P-n junction & throughout; A pair of hole (interface into electricity Is the carrier) And electronic ( Negative carrier) 。 In the each layer of the semiconductor, acceptor, Electronic capture; N) And the donor ( Electronic pitch; P type) Molecules in the face of each other, as a perfect p-n junction. The platinum rhodium thermocouple in the

add battery & other; Battery & throughout; Need a large area of the number of p-n junction, thus produced complex & other; Volume & throughout; P-n junction - This is a kind of similar to fold folding interface. In the complex structure like a maze, due to uneven molecular arrangement, so the carrier is not easy to reach the output electrode of the battery. In simple terms, low crystallinity.

carrier - Electrons or holes - Must be between molecules from the domain as matter waves, in order to effectively achieve high transmission. Carrier wave nature to reveal through ordered molecular arrangement.

molecular science institute, IMS) Japan institute of synchrotron radiation ( JASRI） And science at the university of Tokyo scientists successfully developed a high degree of crystallinity of platinum-rhodium thermocouple p-n junction. In the process of production, receptor ( Perfluorinated pentine) Molecules by molecular beam epitaxy ( MBE） Methods cascade in donor molecules (in the form of good organization Pentacene) The single crystal.

use Angle resolution photoelectron spectroscopy, observe the electronic structure of the crystal p-n junction, and prove receptor molecules layer valence band, which is to improve the wave nature of the evidence. The current research results show that the MBE can make crystal p-n junction, which may cause cavitation and electronic wave properties.

by designing the basic structure of organic molecules, can adjust the function of platinum-rhodium thermocouple. Using a variety of production technology of organic molecular crystals pn junction allows to high energy conversion efficiency to achieve new platinum rhodium thermocouple cell.
