Governments and scientists worldwide are racing to unlock the full potential of perovskite solar cells; what is this next-gen solar tech?
Perovskite solar cells operate on a principle where sunlight interacts with a thin layer of hybrid organic-inorganic lead or tin halide-based perovskite material.Developed by Tsutomu Miyasaka in 2009, perovskite solar cells emerged as a breakthrough in photovoltaics and a promising alternative to traditional solar technologies. The world’s most advanced labs are experimenting with these next-gen solar cells capable of absorbing a broader spectrum of sunlight.
Read on to learn about perovskite solar technology and how it is already bringing a major shift in solar technology. Perovskites are versatile materials known for their exceptional compositional flexibility, making them suitable for various high-tech applications beyond solar cells, such as memory chips and ultrasound machines. Perovskite materials like methylammonium lead halide and all-inorganic cesium lead halide are particularly appealing due to their cost-effectiveness.
About 90% of solar panels use silicon semiconductors, which cannot be processed in a solution bath without risking defects that impair functionality. In contrast, perovskite semiconductors are highly fault-tolerant and can be processed into semiconductor ink, making them suitable for creating lightweight andand car roofs.
The use of lead raises significant health and environmental safety issues, necessitating research into non-toxic alternatives.
