Abstract

The present application discloses a solar cell and a manufacturing method thereof. In addition to a solar cell epitaxial structure, an electrode structure, and a packaging substrate, the solar cell also includes a transparent structure on a side of the solar cell epitaxial structure facing the packaging substrate, and a reflection structure on a side of the transparent structure away from the solar cell epitaxial structure. Thus, the light irradiating the side of the solar cell can be transmitted to the packaging substrate by the transparent substrate, and then is reflected, by the reflectionstructure on a side of the packaging substrate facing the transparent structure, back to the solar cell epitaxial structure. The light absorption amount of the solar cell epitaxial structure is increased, thereby improving the photoelectric conversion efficiency of the solar cell.

Description

technical field [0001] The present application relates to the technical field of solar cells, in particular to a solar cell and a manufacturing method thereof. Background technique [0002] With the rapid development of social economy, the demand for energy is increasing day by day, and the problem of energy shortage is becoming more and more prominent under the condition that fossil fuels are decreasing and non-renewable. Therefore, a new energy source is needed to promote the healthy development of society and the environment. Solar energy is a renewable green energy, and solar cells can use the photovoltaic effect to directly convert solar energy into electrical energy, which has led to the rapid development of the solar cell industry in recent years. [0003] However, the existing solar cells only absorb the light directly above the plane where the solar cells are located, receive limited light, and have a low utilization rate of solar energy, resulting in low photoelect...
