Prototype Development
Prototype Development: Our laboratory actively works on the development of prototype devices, with a particular emphasis on emerging photovoltaic technologies such as perovskite solar cells and chalcogenide-based devices. We integrate our synthesized materials into functional device architectures, enabling systematic evaluation of their optoelectronic properties and photovoltaic performance.
We design and fabricate a range of device structures, including single-junction, tandem, and heterostructure configurations, tailored for specific applications like transparent, flexible, and high-efficiency solar cells. The device fabrication process involves precise layer-by-layer deposition of functional materials, including electron transport layers, absorber layers, hole transport layers, and electrodes, using techniques such as spin-coating, doctor-blading, thermal evaporation, and electrodeposition.
Following fabrication, prototypes are encapsulated and systematically characterized using current-voltage (J-V) measurements under standard illumination, external quantum efficiency (EQE) analysis, impedance spectroscopy, and stability testing under various environmental conditions. These comprehensive evaluations guide the optimization of material compositions and device architectures, facilitating the transition from material development to functional, scalable photovoltaic prototypes.
