The disadvantages of perovskite solar cells

1. Short life (poor stability):
Perovskite solar cells have unstable performance due to their hygroscopicity, thermal instability, ion migration, and external factors such as ultraviolet rays and light. The life of a perovskite solar cell is about 4,000 hours, and its efficiency is only 80% of the initial value, which is far from the 25-year life of the current mainstream photovoltaic technology.
2. Large-area module efficiency problem
At present, the efficiency of large-area modules of perovskite solar cells is still much lower than that of small-area modules, which is one of the problems restricting industrialization.
3. Environmental pollution risk:
Lead-containing perovskites have environmental pollution risks, which is also a problem to be solved in industrialization.
4. Sensitive to the environment
Temperature, humidity, light, circuit load and other factors will lead to the decomposition of perovskites and the reduction of battery efficiency.
5. Complex degradation mechanism
The degradation mechanism of perovskites and their devices is very complex. There is no very clear understanding of this process in the field, and there is no unified quantitative standard, which is not conducive to the study of stability.
Its shortcomings such as short lifespan, large-area module efficiency issues and environmental pollution risks still need further research and resolution.
