Abstract

The invention belongs to the technical field of solar cells and particularly relates to a large-area efficient stable passivated tunneled organic-inorganic hybrid perovskite solar cell and a laminatedcell. The large-area efficient stable passivated tunneled organic-inorganic hybrid perovskite solar cell comprises, when of upright structure, conductive glass, an electron transport layer, an organic-inorganic hybrid perovskite light absorbing layer, a hole transport layer, an ALD (atomic layer deposition) nitride, a heavily-doped hole transport layer and a metal electrode, or comprises, when ofinverted structure, conducive glass, a hole transport layer, an organic-inorganic hybrid perovskite light absorbing layer, an electron transport layer, ALD nitride, a heavily-doped electron transportlayer and a metal electrode. In addition, the passivated electron transport layer or hole transport layer has surface effects, such that carrier interfacial recombination is decreased. The heavily-doped layer helps improve the ability of transporting carriers to an outer circuit. The upright or inverted solar cell may be stacked to a HIT (heterojunction with intrinsic thin-layer) cell to form a large-area laminated cell.

Description

technical field [0001] The invention belongs to the technical field of solar cells, in particular to a large-area, high-efficiency and stable passivation tunneling organic-inorganic hybrid perovskite solar cell and a stacked cell. Background technique [0002] Energy and the environment are the biggest challenges facing global development today. Photovoltaic power generation, one of the clean and renewable energy sources, has developed rapidly in recent years. At present, the power generation cost of crystalline silicon cells has been significantly reduced, but high efficiency and low cost are still the prerequisite for the good development of the photovoltaic industry. In recent years, organic-inorganic hybrid perovskite batteries have developed rapidly, and small areas (less than 0.5cm 2 ) The highest photoelectric conversion efficiency has exceeded 22%. The highest efficiency of organic-inorganic hybrid perovskite / crystalline silicon bottom cells has also exceeded 26%....
