Witryna10 wrz 2024 · Charge extraction by electron transport layers (ETLs) plays a vital role in improving the performance of perovskite solar cells (PSCs). Here, PSCs with four different types of ETLs, such as SnO 2, amorphous-Zn 2 SnO 4 (am-ZTO), am-ZTO/SnO 2, and SnO 2 /am-ZTO, are successfully synthesized. The interface recombination … Witryna10 sty 2024 · The improved charge collection efficiency is mainly caused from faster electron transport, as the electron recombination time is less influenced by our surface modification of Ti wire. The presence of nanopillars over the Ti wire provides more collection area inside the mesoporous layer than a bare Ti wire.
