Indian Scientists Develop Eco-Friendly Solar Cell Material
Indian researchers have created a novel solar harvesting material that substitutes toxic lead with greener magnesium. This marks an important breakthrough for affordable and sustainable photovoltaics.
The Promise and Perils of Perovskite
Perovskite solar cells have shown tremendous efficiency promises at low costs. But mainstream versions use a formulation with toxic lead – hazardous for health and environment.
Seeking a Solution
Scientists at Hyderabad’s International Advanced Research Centre for Powder Metallurgy & New Materials, an autonomous institute under India’s Department of Science and Technology, tackled this challenge.
They synthesized a new perovskite material swapping half the lead for abundant, non-toxic magnesium while retaining efficiency.
Novel Solar Cell Design
The researchers also pioneered a simplified solar cell architecture using this new MAPb0.5Mg0.5Cl2I perovskite formula.
Unlike traditional costly models with gold electrodes, theirs utilizes affordable titanium dioxide and carbon.
Remarkable Performance
This lead-magnesium perovskite photodetector demonstrated:
- High responsivity of 153 mA/W
- Ultra-fast response time of 0.4 milliseconds
- Low bias voltage requirement
The figures meet or exceed various standard solar cell metrics.
