Effects of spectral coupling on perovskite solar cells under diverse climatic conditions

The high conversion efficiency of perovskite solar cells has opened a potential market for solar cells based on low cost manufacturing techniques which could change the photovoltaic (PV) production road map. Although the 9% efficient 10 cm x 10 cm perovskite mini module has been reported, in depth analysis of the longevity of perovskite modules is required before being introduced to the market. Apart from the impressive demonstrated conversion efficiencies, these cells need to be tested under real climatic conditions in order to understand the integrity of their performance. This article briefly outlines significant spectral dependence at selected locations with varying parameters such as air mass, aerosol optical depth and precipitable water. Perovskite solar cells have shown significant dependence on the incident spectrum due to their strong absorption in the visible region. The influences of spectral variations on the performance of perovskite solar cells were studied under different atmospheric conditions. The demonstrated spectral losses by the perovskite solar cells in different climatic conditions are vital for the perovskite solar cell community to further improve their stability.
