In 2009, Mihasaka and colleagues incorporated perovskite semiconductors into photovoltaic devices and reported a power conversion efficiency (PCE) of ∼4% 1. Since then, significant progress has been ...
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 ...
