IIT Guwahati researchers have developed a low-cost perovskite solar cell. The developed devices have a power conversion efficiency of up to 21%. The defect-free device with passivation demonstrates high efficiency of 20.17 percent and excellent reproducibility.
Key Highlight:
- IIT Guwahati has developed hybrid perovskite solar or photovoltaic devices.
- These machines are highly efficient and straightforward to construct.
- Hybrid perovskite, according to officials, is also easily recyclable.
- Solar panel recycling, experts say, is dangerous and complicated.
- It can convert up to 21% of energy.
- To reduce costs, this device was developed at mild room temperature.
- High efficiency of 20.17 percent with excellent reproducibility from the passivated defect-free device
Researchers at IIT Guwahati have developed perovskite-based solar cells to produce electricity from sunlight. The cells are considered the most promising due to their low cost, ease of manufacturing, high material availability and easy recyclability. Researchers at the Indian Institute of Technology, IIT Guwahati, have developed a low-cost perovskite solar cell to generate electricity from sunlight. Due to their low cost, ease of manufacturing as roll-to-roll devices, high material availability, and easy recyclability, perovskite-based semiconducting devices are considered the most promising.
The developed devices have a power conversion efficiency of up to 21%. This efficient device was developed by combining cost-effective solution-based photovoltaic device processing techniques with mild room temperature operation to achieve high ambient, thermal, and optical stability. However, the volatile nature of perovskite materials precludes their commercialization.
Inorganic solar cells (silicon-based) currently account for a sizable portion of the market. However, because this technology requires high-temperature processing, solar panels are pretty expensive. Additionally, solar panel recycling is hazardous and complicated. The defect-free device with passivation demonstrates high efficiency of 20.17 percent with excellent reproducibility. By increasing the hydrophobicity of the perovskite layer, this polymer-based passivation method effectively improved the device’s long-term stability.
The research team at IIT Guwahati, led by Prof. Parameswar K. Iyer and comprised of research scholars Rabindranath Garai (Department of Chemistry), Ritesh Kant Gupta (Centre for Nanotechnology), Arvin Sain Tanwar (Department of Chemistry), and Maimur Hossain (Department of Chemistry), has achieved remarkable results in terms of efficiency and effectiveness.
