Article Synopsis
- Researchers have tackled the challenge of crystal growth alignment in low-dimensional perovskites (LDPs) used for solar cells, specifically those with wide band gaps that hinder charge flow.
- By adding chlorine to the precursor solution, they induced vertical crystal growth which enhances efficiency.
- This method led to a significant power conversion efficiency of 9.4% and an open circuit voltage of 1.4V, paving the way for innovative solar applications in buildings and indoor energy solutions.
Article Synopsis
- Interface engineering is vital for optimizing perovskite photovoltaics (PVs), focusing on reducing unwanted recombination to improve performance.
- A novel approach involves creating a photo-ferroelectric perovskite interface by adding an ultrathin ferroelectric layer to enhance charge separation and reduce voltage losses.
- This innovation has achieved a record open circuit voltage of 1.21 V and a champion efficiency of 24%, demonstrating a promising direction for advanced perovskite PV designs.
Perovskite/silicon tandem solar cells have a tremendous potential to boost renewable electricity production thanks to their very high performance combined with promising cost structure. However, for actual field deployment, any solar cell technology needs to be assembled into modules, where the associated processes involve several challenges that may affect both the performance and stability of the devices. For instance, due to its hygroscopic nature, ethylene vinyl acetate (EVA) is incompatible with perovskite-based photovoltaics.
