Encapsulation of perovskite solar cells and supported nanostructures by ultrathin plasma polymers
Abstract
Remote plasma assisted vacuum deposition (RPAVD) is a very versatile methodology for the synthesis of functional films and multilayers for photonic, sensing, nanoelectronic and biomedical applications. Besides, the RPAVD methodology permits to deposit highly conformal multifunctional organic films to encapsulate fragile supported nanostructures without affecting their molecular structure and atomic bonding. In this work, we use this plasma enabled nanoencapsulation approach to improve the stability of perovskite solar cells under water and moisture exposure. The deposition of the polymer is carried out at room temperature by the remote plasma vacuum deposition of adamantane powder. This encapsulation method does not affect the photovoltaic performance of the tested devices and is virtually compatible with any device configuration independent of the chemical composition. After 30 days under ambient conditions with a relative humidity (RH) in the range of 35-60%, the absorbance of encapsulated perovskite films remains practically unaltered. The deterioration in the photovoltaic performance of the corresponding encapsulated devices also becomes significantly delayed with respect to devices without encapsulation when vented continuously withvery humid air (RH > 85%). Besides the encapsulation is robust enough to let measure the power conversion efficiency of encapsulated devices under operation in water. The proposed method opens up a new promising strategy to develop stable photovoltaic and photocatalytic perovskite devices.
