Semi-transparent solar cells achieve record-breaking energy conversion
The solar cells can be teamed up with tandem solar cells and also pave the way for use in windows to tap into solar energy.
matéria em spoiler:
Researchers at the Korea Institute of Energy Research (KIER) have developed perovskite-based semi-transparent solar cells that have a record-breaking 21.68 percent energy conversion efficiency, a press release said.
These cells can be readily deployed as building windows or with tandem solar cells and have also demonstrated improved durability compared to other perovskite-based solar cells.
High-efficiency solar cells are needed as the world looks to phase out its dependence on fossil fuels for its energy demands. Conventionally deployed solar cells have an energy conversion efficiency of only 20 percent, meaning we cannot tap into 80 percent of light incidents on existing solar infrastructure.
To improve this energy conversion ratio, researchers have been working with materials such as perovskites that can deliver high energy efficiencies. Some teams want to tap into more solar energy by repurposing windows and glass facades as solar panels.
The team at the Photovoltaics Research Department, along with the Energy AI and Computational Science Lab at KIER, have now combined these two approaches to deliver a highly durable perovskite cell that is also highly efficient.
Making semi-transparent solar cells
To make semi-transparent solar cells, the team decided to replace the metal electrodes that make conventional solar cells opaque with transparent ones that allow the light to pass through them. While this might sound like a straightforward thing to do, making these changes have a detrimental effect.
