In inverted perovskite solar cells (PSCs). high-quality perovskite film grown on hole-transporting material (HTM) with pinhole-free coverage and a large grain size is crucial for high efficiency. Here. we report on the growth of pinhole-free and large grain CH3NH3PbI3 crystals favored by a hydrophobic small molecular HTM. https://www.animationbengal.com/?w=mega-price-the-cafe-terrace-on-the-place-du-forum-arles-at-night-c-1888-sale-top-super
