In this work we fabricate all-vacuum processed methyl ammonium lead halide perovskite by a sequence of physical vapour deposition of PbI2 and chemical vapour deposition (CVD) of CH3NH3I under a static atmosphere. We demonstrate that for higher deposi

We report on the preparation, structural characterization, and device performance of heterojunction bilayer organic solar cells (OSC) prepared via a combination of solution and vacuum processing. For a functioning OSC, the electron donor layer consis

Good prospects of organic solar cells (OSC) are dampened by relatively poor transport properties in the organic donor–acceptor (D–A) absorber system. A widely recognized key to overcome this drawback is the ability to control its D–A morphology
