Customer ServiceThis review aims to summarize the significant research work carried out in recent years and provide an extensive overview of the electrodes used till date in perovskite solar cells. We present a critical survey of the recent progress on the aspect of electrodes to be used in perovskite solar cells.
The stability of the perovskite solar cells has been associated with the selection of proper materials for electrodes. Effects such as diffusion of elements from the electrodes to the internal layers, obstruction to moisture and oxygen, proper adhesion, and resistance to corrosion should also be taken under consideration.
Thermal evaporation One of the most recent approaches for fabrication of the perovskite solar cell is the vacuum thermal evaporation. It was firstly introduced by Snaith et al. where he fabricated the first vacuum-deposited film by co-evaporation of the organic and inorganic species .
For perovskite solar cells, in order to reach the category of commercial photovoltaic technology, the most significant obstacle is the long-term device stability. Though the common metal electrode-based devices have exhibited high power conversion efficiency, they play a vital role in accelerating the degradation of the devices.
Each component layer of the perovskite solar cell, including their energy level, cathode and anode work function, defect density, doping density, etc., affects the device's optoelectronic properties.
