Researchers at the Aalto University in Finland have proposed a new simplified method for testing perovskite and dye-sensitized solar cells. The researchers explained that their fast low-threshold photographic method can detect even slightly aged parts of the perovskite battery, are more reliable than optical measurements, and are simpler than the more commonly used X-ray crystallographic inspection procedures. By observing the color change of iodide ions and perovskites in the dye-sensitized solar cells, the aging degree of the battery is judged. The longer the battery is used, the longer the time of the use of the battery, the more gradually the iodide ions will change from bright yellow to transparent and the perovskite will change. Yellow is darker. However, current battery aging test methods still have some drawbacks. More rigorous aging test methods are critical to prolonging battery life. The team has proposed several methods to extend the battery life. Professor Kati Miettunen said: "Understanding the mechanism of battery aging is very important. We have managed to extend the life of solar cells by more than ten times by changing the structure of the battery and the electrolyte." Previous research at Aalto University, due to the small sample size and lack of detailed information on environmental conditions such as temperature, humidity, etc., most perovskite solar cell aging tests failed to provide accurate data. The research team stated that it will hold a series of meetings and cooperate with other experts to establish clear standards for aging tests. "High-quality, standardized testing will enhance investor confidence in the solar cell industry."
