Abstract
This invention relates to the use of Li-vermiculite films as flexible inorganic substrates that are light-weight, electrically insulating and thermally stable at 450-700° C. These films are coated with molybdenum and used in the fabrication of thin-film photovoltaic cells. This invention also relates to photovoltaic cells incorporating such flexible inorganic substrates.
