According to authorities, researchers at the Indian Institute of Technology (IIT) Guwahati have created hybrid perovskite solar cells (PSC) or photovoltaic devices to generate power from sunlight that is highly efficient, cost-effective, easy to fabricate, and can be recycled without breaking a sweat.
These devices have achieved more than 21% efficiency in power conversion by utilizing affordable solution-based photovoltaic device manufacturing techniques at moderate room temperature and bring in excellent ambient, optical and thermal resilience.
PSC is a form of solar cell in which the light-harvesting active layer is a perovskite-structured compound, most typically a hybrid organic-inorganic lead or tin halide-based substance.
However, the perovskite materials are exceedingly unstable in the presence of humidity and oxygen, which limits their commercialization.
Because of the introduction of extremely efficacious functional materials paired with careful device engineering, organic-inorganic hybrid PSCs have shown tremendous progress in terms of efficiency and stability, said Professor Parameswar K Iyer of the institute’s Department of Chemistry and Centre for Nanotechnology and School for Health Science and Technology, who oversaw the research.
“Materials can be tailored at the molecular level, and the production method is printable and solution-based, making the total solar cell development process cost-effective and scalable,” He stated.
Currently, inorganic solar cells (Silicon-based) are a big market participant. These cells necessitate high-temperature manufacturing, which raises the cost of solar panels. Furthermore, recycling solar panels is risky and complex.
In accordance with the professor, the findings achieved from PSCs outperformed the commercial inorganic solar cell panels currently available on the market.
“Also, these small and large area devices performances are among the best results achieved using these classes of perovskite materials,” he said.
According to Iyer, the finding has the potential to overcome the renewable energy issues associated with the large-scale commercial manufacturing of efficient and stable solar panels.
The team believes that solar energy is the most sustainable, of all renewable energy sources, owing to its abundant availability on the earth’s surface.
