Problems solved by technology

[0003] The perovskite light-absorbing layer has a band gap of about 1.5eV, which can absorb visible light well, but it is transparent to the near-infrared region, which directly leads to a decrease in the efficiency of perovskite solar cells.

Abstract

The invention provides an efficient copper indium gallium selenide / perovskite series solar cell. The four-terminal series solar cell comprises a semitransparent planar heterojunction perovskite solar cell and a copper indium gallium selenide (CIGS) solar cell which are connected in series. The series solar cell can overcome the shortcoming that the perovskite solar call cannot absorb near-infrared light; the efficient copper indium gallium selenide / perovskite series solar cell can effectively absorb ultraviolet light, visible light and near infrared light, so that the solar cell efficiency can be improved; and a new thought for the final commercialization of perovskite is provided.

Description

technical field [0001] The invention belongs to the field of semiconductor optoelectronic devices, in particular to the field of copper indium gallium selenide / perovskite tandem solar cells. Background technique [0002] With the depletion of non-renewable resources such as coal, oil and natural gas, new energy, especially solar cells, has become a hot spot of research at home and abroad. At present, inorganic silicon solar cells have been industrialized, but their cost is too high, and the efficiency of organic solar cells is too low, so the prospects are not clear. Since the first report in 2009, perovskite solar cells have been favored by researchers for their ultra-low-cost solution preparation process. The energy conversion efficiency has increased from the initial 3.8% to 20.1%. With the deepening of research, The efficiency of the cell is very likely to exceed that of the currently developed monocrystalline silicon solar cells. [0003] The perovskite light-absorbin...
