Problems solved by technology

However, the current conventional high-efficiency photovoltaic cells, such as silicon and copper indium gallium selenide cells, have low operating voltages. In actual use, several solar cells need to be integrated in series to generate photoelectromotive force for splitting water.
This requires the balance of light absorption and photocurrent in each solar cell to effectively drive the hydrogen production reaction, but the current architecture is complicated to manufacture and does not have the ability to produce hydrogen economically.

Abstract

The invention relates to a water-electrolytic hydrogen making integrated device for a perovskite solar cell and a manufacturing method for the integrated device. According to the integrated device and the manufacturing method, the perovskite solar photovoltaic cell is originally connected in series with a photochemical cell, and the perovskite solar cell is connected in parallel with the photochemical cell by utilizing the advantage of high output voltage of the low-band-series perovskite solar cell, so that water-splitting hydrogen making is performed without an external bias power supply, and direct energy conversion from solar energy to hydrogen energy is realized; during use, a low-band-series perovskite material can absorb short-wave sunlight and a wide-band-series photochemical cell material can absorb long-waveband sunlight, so that the utilization rate of the sunlight is effectively increased; and when the perovskite solar photovoltaic cell is manufactured, a TiO2-coated Au/Ag core-shell layer is directly used as an electron transmission layer without the need for additionally making a special electron transmission layer, so that a manufacturing process is simplified, the production cost is reduced, the light absorption of a perovskite layer is facilitated, and the light absorption effect of the solar cell is improved.
