Methods and materials for light-heat conversion.

摘要

The disclosure is directed to a method for converting between heat energy and electric energy which is characterized in that a carbon intercalation compound is employed as a thermoelectric material by utilizing temperature difference in a direction perpendicular to the structure of carbon layers, or a method for producing a light-heat converting material which is characterized in that a thin metallic layer like a translucent mirror is caused to adhere to the inner surface of a light transmissive hollow tube by pyrolytically decomposing at a temperature approximately below 1000 DEG C, with hydrocarbons being introduced into the hollow tube (3) at the rate of a predetermined amount an hour.
