Annotation:
Solar cells are one of the most prominent and promising energy technologies today. It is sustainable, renewable, clean, completely noise-free, scalable, requires minimal amount of maintenance and produces zero emissions.
The ternary compound (I–III–VI2) semi-conductor CuInSe2 is one of the leading materials for large-scale solar applications. It has a direct band gap, a high absorption coefficient, stability against photodegradation and good thermal stability. Copper selenide is a semi-conducting material, which exhibits electrical and optical properties suitable for photovoltaic application.
This thesis is related to the search of new effective methods to obtain copper and indium selenide layers. Copper and indium selenide layers were obtained on glass using a low cost, simple successive ionic layer adsorption and reaction (SILAR) method. This method produces homogeneous layers and allows for easy scalability for large surface area coatings.
