Solar Discovery: New Study Supports Efficiency Beyond 20%

A global team of researchers, including scientists from the University of Melbourne, UNSW, and ANU in Australia. The researchers discovered a new method to enhance the performance of silicon solar cells by incorporating a thin layer of caesium bromide (CsBr). 

This layer helps the solar cell components connect more effectively, allowing the cell to generate more electricity. When combined with titanium oxide (TiOx) and heated to 250°C, the solar cells reached an impressive efficiency of 20.5%. 

This is a big improvement over older solar cell designs, which often waste some sunlight. The discovery could lead to stronger and cheaper solar panels. Researchers say using reflective materials like silver could make them even more efficient. 

The study, done with universities in China, the Netherlands, and Germany, was published in Progress in Photovoltaics. It shows that small changes in design can make a big difference in solar energy performance.
