Abstract

The invention provides a manufacturing method for a perovskite solar cell with a compound electronic transmission layer structure. The method is characterized by comprising the following steps: (1) spin-coating a SnO2 compact layer on a conductive glass layer and then putting into a muffle furnace for burning for 1h at 180 DEG C; (2) dissolving iodine methylamine and lead chloride at mole ratio of (5:1)-(1:1) into N,N-dimethyl formamide, forming a solution, using a gluing machine for depositing the solution on the SnO2 compact layer, controlling the temperature at 70-150 DEG C and crystallizing, thereby acquiring a methylamine lead iodine polycrystalline film; (3) uniformly coating the organic solution of a hole-transport material onto the methylamine lead iodine polycrystalline film, thereby forming a hole-transport material layer; (4) adopting an evaporation method for evaporating a silver electrode layer on the hole-transport material layer. The cell produced according to the method provided by the invention has higher photovoltaic conversion efficiency; the compounding technique is simpler; the prepared SnO2 compound electronic transmission material is performed under lower temperature below 180 DEG C; the energy consumption of the cell is reduced; the cost is saved.

Description

technical field [0001] The invention relates to a method for manufacturing a solar cell, in particular to a method for manufacturing a perovskite solar cell with a composite electron transport layer structure. Background technique [0002] Perovskite solar cells have received great attention from scientific research and industry due to their low cost, good performance, and simple preparation. Perovskite materials have been used in solar cells since 2009, and the efficiency has reached nearly 20%, which is 5 times the initial cell efficiency, leaving behind new thin-film solar cells such as dye-sensitized solar cells and organic solar cells. , Perovskite solar cells are low-cost thin-film solar cells that have developed very rapidly in the past three years. [0003] The core of the perovskite solar cell structure is the perovskite crystal form ( ABX 3 ) of organometallic halide light-absorbing materials. In this perovskite ABX 3 In the structure, A is a methylamino group...
