Abstract
There is disclosed a method for making solar cells with sensitized quantum dots in the form of nanometer metal crystals. Firstly, a first substrate is provided. Then, a silicon-based film is grown on a side of the first substrate. A pattern mask process is executed to etch areas of the silicon-based film. Nanometer metal particles are provided on areas of the first substrate exposed from the silicon-based film. A metal electrode is attached to an opposite side of the first substrate. A second substrate is provided. A transparent conductive film is grown on the second substrate. A metal catalytic film is grown on the transparent conductive film. The second substrate, the transparent conductive film and the metal catalytic film together form a laminate. The laminate is inverted and provided on the first substrate. Finally, electrolyte is provided between the first substrate and the metal catalytic film.
