Brief Profile

Overcoming upscaling challenges in perovskite fabrication Despite high efficiency records of perovskite solar cells, it is yet to be commercialized. The problem of lead toxicity, instability on exposure to air and sunlight, decline in efficiency on moving from small area to big area and unreproducible processing techniques must be overcomed prior to commercialization. Thus, the main focus of this research is to source for non-toxic lead free materials, mitigate instability, trap states and j-v curve hysteresis using interface engineering and fabricating a large area perovskite solar cells using scalable processing techniques such as spray deposition, slot-die coating, ink-jet processing, blade coating, etc. The emphasis is to develop an optimized scalable platform using a linear stage tha
