Researchers in China have built a hole transport layer with a mixed binary configuration integrating the polymer Regioregular poly(3-hexylthiophene) (P3HT) and Spiro-OMeTAD. They used it to build a perovskite solar cell that was able to retain 90% of its initial efficiency after 1,200 hours of storage in dark ambient environment.A group of researchers led by the Chinese Academy of Sciences (CAS) has built a perovskite solar cell based on a binary mixed hole transport layer (HTL) that reportedly offers better performance than HTLs that rely on commonly utilized hygroscopic dopants. "These dopants ...Den vollständigen Artikel lesen ...
