About this Research Topic
The world faces contemporary energy problems due to technological developments and large energy consumption. Advanced energy systems should be developed to replace fossil fuel use in order to ensure a sustainable future environment. Towards that goal, organic/perovskite solar cells and electricity generators have been widely studied as candidates for next-generation energy systems, due to their great potential as wearable, light-weight, flexible and environmentally friendly power sources.
Through regulation of the energy levels, band gaps, electrochemical behaviors, optical and electrical properties and contact characteristics of the active components in these devices, it is possible to create a path towards solving the electron generation and conversion issues and fulfill the future energy needs. Some of the strategies towards increasing the performance of these devices are: i) synthesis of low-band gap active layer materials with a wide absorption range, ii) preparation of work-function adjustable buffer layers for charge transport, iii) regulation of electron structures and molecule vibration conductive molecules, iv) development of both device structures and solution-manufacturing, etc.
The aim of this Research Topic is to highlight the progress and phenomena related to wearable electricity generators and organic/perovskite photovoltaics. We especially welcome contributions that focus on the increase of performance in efficiency, stability and mechanical property for the solar cells, as well as high and continuous electric outputs for the electricity generators. In particular, research themes may include, but are not limited to:
• Both new functional materials and strategies are introduced in the wearable electricity generators and solar cells.
• Energy levels, band gaps, electrochemical behaviors, optical and electrical properties and contact characteristics are regulated to raise electricity generation and charge-carrier transport and extraction.
• Compensation and polarization of ions and electronic charges are adjusted to create electrical potentials for electric outputs.
