Special Issue Information

Dear Colleagues,

Almost 10 years after their first use in the photovoltaic field, perovskite solar cells (PSCs) are now hybrid devices that, in addition to having reached silicon performance, can accelerate energy transition and boost the use of abundant elements for their manufacturing process. However, use of precious metals, scarcity of large-scale fabrication processes able to prepare modules with reproducible performances, and a worldwide accepted aging protocol still slow down the industrialization of this technology.

The aim of this Special Issue is to collect high-profile articles and reviews proposing novel strategies towards upscaling and stabilization of PSCs. Novel front- and back-electrode solutions, emerging solar cells’ fabrication at large scale, integration of PV units with energy-storage technologies, replacement of costly metals, and significant long-term stability tests will be welcomed and diffused in the widespread Molecules scientific community.

With the rapid consumption of energy, clean solar energy has become a key study and development subject, especially the when new renewable energy perovskite solar cells (PSCs) are involved. The doping method is a common means to modulate the properties of perovskite film. The main work of this paper is to incorporate trace amounts of alkali metal elements into the perovskite layer and observe the effects on the properties of the perovskite device and the majority carrier type of the perovskite film. Comparative analysis was performed by doping with Na+, K+, and Rb+ or using undoped devices in the perovskite layer. The results show that the incorporation of alkali metal ions into the perovskite layer has an important effect on the majority carrier type of the perovskite film. The majority carrier type of the undoped perovskite layer is N-type, and the majority carrier type of the perovskite layer doped with the alkali metal element is P-type. The carrier concentration of perovskite films is increased by at least two orders of magnitude after doping. That is to say, we can control the majority of the carrier type of the perovskite layer by controlling the doping subjectively. This will provide strong support for the development of future homojunction perovskite solar cells. This is of great help to improve the performance of PSC devices. Full article
