New Solar Cells Aims to Exceed 30% Efficiency

Researchers have developed a new type of solar cell that combines a wide-bandgap perovskite cell with a narrow-bandgap cadmium selenium telluride (CdSeTe) cell. This four-terminal (4-T) tandem solar cell is designed to exceed the efficiency limit of traditional single-junction solar cells. They've managed to achieve an efficiency of about 25% and have a plan to push this to over 30%.They used a method called radio frequency (RF) magnetron sputtering to make an indium zinc oxide (IZO) film for the TBC. By adjusting the sputtering parameters, they were able to optimize the IZO film's properties for the semi-transparent perovskite cells.

To improve the efficiency of these solar cells, the researchers have a roadmap that includes:

1.Using the best available technology for both perovskite and CdSeTe cells.

2.Reducing energy losses due to non-radiative recombination in the perovskite layer.

3.Improving the conductive properties of the TBC.

4.Enhancing the CdSeTe cell's voltage and fill factor (FF) through various strategies.

By following this roadmap, they believe that it's possible to create 4-T tandem solar cells with an efficiency of over 30%.This would be a significant advancement in solar cell technology, making it more efficient and potentially more cost-effective.
