Solar cells based on thin-film architectures offer potentially cheaper production, semi-transparency, and flexibility. Slot-die coating is one of the most promising scalable and roll-to-roll compatible deposition method for thin-film solar cells. Printing thin-film layers from colloidal quantum dot solution offers the advantage of decoupling the crystallization from the deposition process. Perovskite quantum dots are one option for high-quality next-generation perovskite solar cells. We demonstrate the feasibility of fabricating solar cells from printed quantum dots as the active layer. Extensive characterization by SEM and grazing-incidence X-ray scattering gives insights into the morphology, structure, and texture. SEM, FLIM, PL, and transient PL measurements shed light on the optoelectronic properties of the solar cell printed from colloidal hybrid perovskite quantum dot solution.
