8.91% Power Conversion Efficiency for Polymer Tandem Solar Cells. (19th December 2013) - bin Mohd Yusoff, Abd. Rashid
Abstract A power conversion efficiency of up to 8.91% is obtained for a solution‐processed polymer tandem solar cells based on a large‐bandgap polymer, poly(4, 4‐dioctyldithieno(3, 2‐b:2′, 3′‐d)silole)‐2, 6‐diyl‐alt‐(2, 1, 3‐benzothiadiazole)‐4, 7‐diyl) with a polymeric interconnecting layer to electrically connect the front and rear subcells, demonstrating that proper device and interface engineering are can improve the performance of polymer tandem solar cells.
