Researchers in India have built the 4T device with top and bottom cells based on large-area semi-transparent perovskite cells with copper metal contacts. Copper has been used instead of expensive gold with the aim of reducing the cell's overall cost.Researchers from the Indian Institute of Technology Bhilai have fabricated a four-terminal (4T) perovskite/silicon tandem solar cell that relies on a large-area semi-transparent perovskite cell with a metal contact based on copper instead of expensive gold for both the 4T device's top and bottom cells. "Copper has been used with the aim of reducing ...Den vollständigen Artikel lesen ...
