Heteroatom additive boosts efficiency and longevity of tin perovskite solar cells
Metal halide perovskite solar cells (PSCs) are promising candidates for next-generation photovoltaics because of their high efficiency and low manufacturing cost. While lead-based perovskite devices achieve high power conversion efficiencies, their toxicity hinders commercialization.
Tin perovskite cell longevity and efficiency improved by heteroatom additive
Researchers in Japan have minimised tin-based pervoskite solar cell oxidisation, which affects the efficiency and longevity of the cells, by creating a multifunctional passivation strategy, and progressing the technology toward commercial viability.
The perovskite solar cells are even closer to commercialization. After showing promising laboratory yields, the technology has just proven its worth on a large scale in China. Tested in real-world conditions, it has produced more electricity than silicon panels.
Researchers have achieved an efficiency of 23.5 percent with a perovskite solar cell that does not use traditional stabilizing additives. What's more, the cell retained 99 percent of its initial performance even after 3,000 hours of testing, pv magazine reported.
