Emilio Palomares, Núria F. Montcada, ... Gerrit Boschloo Methods based on photovoltage and photocurrent transients are powerful characterization tools for perovskite solar cells. Such methods are easy to apply on solar cell devices and allow for characterization under conditions that are very close to operational conditions.
Moreover, perovskites can be a potential material for the electrolytes to improve the stability of batteries. Additionally, with an aim towards a sustainable future, lead-free perovskites have also emerged as an important material for battery applications as seen above.
Following that, different kinds of perovskite halides employed in batteries as well as the development of modern photo-batteries, with the bi-functional properties of solar cells and batteries, will be explored. At the end, a discussion of the current state of the field and an outlook on future directions are included. II.
First published on 8th December 2021 Impedance spectroscopy (IS) has great potential to become a standard technique for the characterisation, analysis, and diagnosis of perovskite solar cells (PSC). However, the interpretation of IS data from PSC is still challenging due to the large number of dynamic processes which are not yet fully understood.
Moreover, the unique structure imparts distinctive properties to perovskite materials, making them versatile and highly desirable for various applications, such as solar cells [3, 4], light-emitting diodes (LEDs) , Lasers , batteries, and supercapacitors [, , ], as shown in Fig. 1.
Hence, the engineering of the perovskite films and the microscopic investigation are essential for the further improvement in the perovskite solar cells. Additives acting as surface and GBs modifiers were also shown to improve the performance of PSCs, via affecting morphology as well as the passivation of surface traps.
