Interface engineering is crucial for advancing hole transport layer-free carbon-based perovskite solar cells (HTL-free C-PSCs). Tailoring the perovskite/carbon electrode interface can overcome performance limitations and enhance stability.
Area of Science:
- Materials Science
- Renewable Energy
- Photovoltaics
Background:
- Hole transport layer-free carbon-based perovskite solar cells (HTL-free C-PSCs) offer enhanced stability and low cost.
- Their power conversion efficiencies (PCEs) lag behind theoretical limits due to interface issues.
Purpose of the Study:
- To review recent progress in interface engineering for HTL-free C-PSCs.
- To focus on modifications at the perovskite/carbon electrode interface.
- To provide an outlook on challenges and opportunities for improving PCEs and stability.
Main Methods:
- Review of existing literature on interface engineering in C-PSCs.
- Analysis of strategies to improve perovskite/carbon electrode contact and energy band alignment.
- Examination of methods to enhance light reflection by the carbon electrode.
Main Results:
- Key challenges include poor physical contact, energy band mismatch, and light reflection issues at the perovskite/carbon interface.
- Various interface engineering strategies have been developed to address these challenges.
- Tailored interfacial engineering shows promise for advancing C-PSC performance.
Conclusions:
- Interface engineering is critical for unlocking the full potential of HTL-free C-PSCs.
- Further research into optimizing the perovskite/carbon interface is needed to boost efficiency and long-term stability.
- Addressing interfacial limitations is key to making C-PSCs competitive with conventional solar cells.

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
