Abstract

Provided is a method for manufacturing a solar cell. The method comprises the following steps: a photovoltaic conversion structure is provided; an inorganic transparent conductive layer is formed on a surface of the photovoltaic conversion structure; an organic transparent conductive layer is formed on a surface of the inorganic transparent conductive layer; a patterned transparent protection layer is formed on a surface of the organic transparent conductive layer; the patterned transparent protection layer has an opening, and part of the surface of the organic transparent conductive layer is exposed; the organic transparent conductive layer is subjected to an electroplating technology as a crystal seed layer; an electrode is formed in the opening of the patterned transparent protection layer; the electrode and the organic transparent conductive layer contact and are electrically connected. The method can shorten the technology time and lower the cost, reduces reflection, increases the light entering amount effectively, increases the short circuit current density, and further raises the photoelectric conversion efficiency of the solar cell. In addition, the filling factor can be increased, and therefore the photoelectric conversion efficiency of the solar cell is raised.

Description

technical field [0001] The invention provides a solar cell and a manufacturing method thereof, especially a solar cell with high photoelectric conversion efficiency and a manufacturing method thereof. Background technique [0002] The energy used by humans today mainly comes from petroleum resources, coal mines, natural gas, and nuclear energy. The reserves of petroleum resources have been gradually exhausted after years of continuous mining. Coal mines and natural gas will produce air pollution and pollution due to high carbon dioxide emissions. Greenhouse effect and other issues, and the high risk of nuclear energy is also worrying, so the voice of seeking alternative energy has been increasing in recent years. Among alternative energy sources including wind power, tidal power, and solar energy, the development of solar energy has the greatest potential, and many countries have invested in the research and development of solar power generation technology. [0003] The pri...
