Introduction The search for low cost alternatives to inorganic semiconductors resulted in a growing interest in organic materials [1].
In addition, hybrid organic/inorganic structures seem to offer a viable solution for solar cells due to utilizing the large carrier mobility in inorganic materials and the strong photo-absorption coefficient in organic materials.
Therefore, it may be possible to easily find an optimal combination of two kinds of semiconductor materials in order to improve the solar cell’s performance.
Surface texturization process of inorganic semiconductor materials may reduce optical reflectance and enhance effective light absorption [10, 11].
