Optoelectrical measurements on thin film solar cells. - Development of semiconductor layers and thin films. - Simulation of ion implantation profiles. - Ion implantation for doping semiconductor layers. - Chemical bath deposition. - Thermal annealing. - Sputtering of metallic oxide contacts. - Image analysis - Characterization measurements - Determination of doping profiles, spectral response, elemental depth profiles.

Performed simulations for planning experiments involving ion implantations in p-type Cu(In,Ga)Se2 material. Carried out several experiments to improve the device properties of heterojunction solar cells and to improve the quality of the individual layers. Gained hands-on experience with: - Chemical Bath Deposition technique for fabrication of the cadmium sulphide (CdS) buffer - Sputtering machines for the deposition of solar cell's front contacts (Window layer and metal contacts).

Performed teaching duties for different courses including: - Micro-controllers and interfacing - Digital logic circuits - Experimental physics lab - Modern physics - Electro-mechanical systems Supervised lab sessions, conducted tutorials and prepared help material for students for an in-depth study of the subject.

Designed and optimized a low power RF-PCB using Advanced System Design. Worked in Linux environment to develop wireless sensor network protocols for an irrigation system.

Designed a high-power density inverter using semiconductor power devices (IGBTs, MOSFETs, Diodes). Simulated the circuit topology on the software PSIM and implemented the final electrical circuit on a PCB.

As part of "Solar panel monitoring program", designed and implemented a microcontroller based circuitry for interfacing the solar panel with a computer Monitored electrical characteristics of a photovoltaic panel by developing a user interface and a control circuit on MATLAB, which extracted, processed and displayed the output parameters of the panel on a PC.
