Abstract

The invention discloses a cascade polymer solar cell and a preparing method of the cascade polymer solar cell. The solar cell comprises a substrate, two (or more than two) cell units, interval layers connecting all layers and a packaging layer packaging the polymer solar cell. The two (or more than two) cell units are electrically separated by the transparent interval layers formed by usage of atomic layer deposition (ALT) technology, absorption of solar spectrums of each cell is not influenced, and integral sunlight absorptivity of the cascade cell can also be optimized through adjustment of the thickness of the interval layer. In addition, the design basically separates electrical design from optical design, and design cost is effectively reduced. Meanwhile, ALD film has the advantages of being good in compactness and good in adhesion and the like, can effectively protects the cell units below the film layer from being eroded by water and oxygen in outside air, and plays a role in packaging and prolongs service life of the cell.

Description

technical field [0001] The invention belongs to the field of solar cells, in particular to a cascaded polymer solar cell and a preparation method thereof. Background technique [0002] Energy issues have always been hot issues affecting human survival and development. With the expansion of the economy, the demand for energy continues to soar, and the consumption of traditional fossil energy is huge. Fossil energy is a non-renewable resource, and the excessive use of fossil energy by humans will inevitably cause serious environmental problems. Therefore, the development of pollution-free and renewable new energy is an urgent task for mankind. Solar energy is a clean, efficient and inexhaustible new energy source, and it will definitely be an important new energy source that human beings rely on in the future. [0003] The application of solar cells began with the development of the aerospace industry in the middle of the last century. So far, it can be divided into three ...
