Researchers Unveil Ultra-Efficient Tandem Organic Solar Cell With Unprecedented Efficiency

The new gadget is made up by an extremely transparent front cell that integrates a transparent ultrathin silver (Ag) electrode of just 7nm, which guarantees its efficient operation.Two-terminal tandem natural solar cells (OSCs) stand out as a leading option for conquering the concerns of transmission and thermalization losses seen in single-junction solar cells. Making tandem organic solar cells of these types is challenging because they need a robust interconnection layer capable of helping with efficient charge recombination while preserving high transparency.The Four-Terminal Tandem ConfigurationThe four-terminal tandem setup has actually emerged as an extremely effective alternative technique in solar cell style. Unlike the two-terminal technique, this setup includes separate electrical connections for the transparent front cell and the nontransparent back cell.

Fabricating tandem organic solar cells of these types is challenging since they require a robust affiliation layer capable of facilitating effective charge recombination while keeping high transparency.The Four-Terminal Tandem ConfigurationThe four-terminal tandem configuration has emerged as an extremely efficient alternative technique in solar cell design. Unlike the two-terminal method, this configuration includes separate electrical connections for the transparent front cell and the nontransparent back cell. It must present a delicate balance, being transparent adequate to enable light to reach the back cell while keeping high electrical conductivity to make sure the optimum performance of the front cell,” stated Francisco Bernal, ICFO researcher and very first author of the research study. “Being able to fabricate an electrode of just 7nm without observing losses in the front transparent cells is a substantial development in the field of transparent cells.
