FLEXIBLE THIN FILM SOLAR SELL COMPRISING SODALIME GLASS INSULATING LAYER AND METHOD OF PREPARING SAME

摘要

According to the present application, a soda lime glass insulating layer containing sodium may be provided between a metal substrate and an electrode. In addition, sodium may be provided to a light absorption layer from a soda lime glass layer. In addition, by controlling a thickness of the soda lime glass layer, the supply amount of the sodium provided to the light absorption layer may be controlled. In addition, by controlling the thickness of a SiO_2 layer not containing the sodium and the soda lime glass layer containing the sodium, a high breakdown voltage may be obtained and the supply amount of the sodium may be exactly controlled.
