ZnO-ZnS THIN FILM BY SCREEN PRINTING TECHNOLOGY FOR PHOTOVOLTAIC CELLS

Thin-film solar cells using quantum dots would fill the future energy need. We know that the wide-band gap II–VI quantum dot semiconductor compounds such as ZnS and ZnO are widely used in optoelectronic devices, such as solar cells, sensors and in many. Printed electronics is a printing method used to create electrical and electronic devices on various substrates. Screen printing is one of the printed electronics method for fabricating electric and electronic devices due to its ability to produce patterned, thin layers from paste-like materials. This article discusses the trials in making thin films using screen printing technique with the quantum dots of ZnO- ZnS semiconductors which were already synthesised by simple solvo-thermal method and also explains how the films could be used in solar cells.
