Carbazole derivatives, such as MeO-2PACz and 2PACz are known to improve the performance of halide perovskite solar cells by facilitating hole transfer. To assess their interaction with halide perovski...

Interfacial band alignment in two-dimensional (2D)/three-dimensional (3D) perovskite heterostructures is crucial for maximizing separation, extraction, and collection of charge carriers, which, in tur...

With the former president now in hospice care, Pulitzer Prize-winning biographer Kai Bird looks back on Jimmy Carter’s environmental record in the White House — from his sweeping protection of Alaska’...

Spiro-OMeTAD, an organic hole transport layer, has made its impact in designing efficient solar cells and light emitting devices. The four oxidation states, which maintain a redox equilibrium, facilit...
