Phonon cell used in phonon accumulator or panel, consists of conversion layer containing specific compound semiconductor having band gap below preset value

摘要

A phonon cell consists of conversion layer containing group II-IV compound semiconductor having band gap of less than 0.5 eV, preferably less than 0.3 eV. The semiconductor contains organic polymer with water content of 0.05-1.0 %mass. Independent claims are included for the following: (1) use of the phonon accumulator or panel to autonomous uninterrupted power supply; and (2) use of the organic polymer.
