Laser nanofabricated metal nanoparticles for enhancing electro-optic devices

Start date

End date

01 October 2011


Irradiation of thin metal films with moderate laser power is used to form metal nanoparticle coatings which can be used in electro-optical devices such as thin film solar cells and chemical sensors. The importance of this technique is the easy scalability, suitability for industrial production with no production of hazardous wastes.

Aims and objectives

Laser nanofabrication of size controlled metallic nanoparticles to enhance the efficiency of electro optic devices such as solar cells. Moreover use of laser nanostructuring to form nanoparticles in specific patterns on substrates for chemical sensors.

Successfully demonstrated fabrication of metal nanoparticles on ceramic and polymers substrate materials with control over their size, optical and electrical properties. Incorporation into organic solar cells enhanced their power conversation. Furthermore use of them into chemical sensors increased their sensitivity.
