NANOTEXTURED OPTOELECTRONICS

Collaborators:

The utilization of nanoscale texturing has been widespread in enhancing light trapping and light in-coupling across various optoelectronic and photonic devices. My research involves employing Lumerical finite-difference time-domain (FDTD), MATLAB and Device simulations to explore the effectiveness of nanostructures in capturing light for prospective photovoltaic devices.

PEROVSKITE SOLAR CELLS

Supervisor: Dr. Mainul Hossain

Collaborators:

Density Functional Theory (DFT) calculations are utilized to explore numerous dopants and co-dopants across the periodic table, aiming to identify elements capable of enhancing both the optical properties, such as light absorption, and electrical properties for solar cell applications. Subsequently, I fed the parameters extracted from DFT calculations into device simulators to obtain the electrical characteristics of the envisioned solar cell device.

Prof. Dr. Jaker Hossain (RU)

State-of-the-art single-junction solar cells are yet to achieve high power conversion efficiency (PCE) as well as high open circuit voltage (Voc) and therefore exceed the Shockley-Queisser limit. Herein, I employed solar cell capacitance simulator-1D (SCAPS-1D) and MATLAB, to propose and demonstrate highly efficient novel 2T, 4T and 6T next generation tandem photovoltaics with high open circuit voltage.

JUNCTIONLESS SOI ISFETS

Ion-sensitive field-effect transistors (ISFETs) are increasingly appealing for label-free biosensing applications owing to their affordability, minimal consumptions, compact dimensions, straightforward on-chip integration, and capacity for rapid electronic detection in real-time. In my work, I used Silvaco Atlas TCAD simulations to design and model next generation of ISFETs.

METAMATERIAL BASED BROADBAND ABSORBERS

Metamaterials-based broadband absorbers are crucial because they can efficiently absorb a wide range of electromagnetic frequencies, making them valuable for stealth technology, solar energy, thermal imaging, communication, and sensing. My works involves employing CST Microwave Studio to design an ultra-wideband metamaterial solar absorber that achieves nearly perfect absorption across the entire spectrum from ultraviolet to near-infrared wavelengths.

Hardware Projects

SOCCER-BOT

I designed and developed a soccer bot using Arduino Uno, BTS module, Bluetooth module, Sonar, and controlled it via a Bluetooth-enabled app created with MIT App Inventor.

PCB DESIGN AND FABRICATION

I utilized Proteus for schematic design, PCB footprint creation, and subsequently I fabricated the physical PCB.
