Transparent solar cell with polarization absorption function

Abstract

The invention discloses a transparent solar cell with a polarization absorption function. The transparent solar cell comprises a substrate, a solar cell body and a packaging layer. The solar cell body is composed of a transparent anode film layer, a photovoltaic conversion layer and a transparent cathode film layer, wherein a metal grating is embedded in the photovoltaic conversion layer. According to the transparent solar cell with the polarization absorption function, plasma of the metal grating embedded in the photovoltaic conversion layer has an enhancement effect, so that the number of photons per unit area absorbed by the photovoltaic conversion layer is increased by 45.3% compared with a traditional transparent solar cell; meanwhile, a grating structure is adopted, so that the collection area of an electrode couple charge carrier is enlarged, the internal quantum efficiency of a device is improved, and higher photovoltaic conversion efficiency is realized.

Description

technical field [0001] The invention belongs to the field of solar cells, in particular to a polarized absorption transparent solar cell. Background technique [0002] In the past 50 years, the energy consumption rate of human society has increased rapidly. Since today's energy mainly comes from thermal power generation, this has directly led to a rapid decline in the reserves of non-renewable energy such as coal, oil, and natural gas on the earth. On the one hand, due to the limited reserves of the above-mentioned energy sources, they cannot be supplied to human society for a long time; on the other hand, the destruction of the ecological environment due to the burning of fossil fuels will have an immeasurable negative impact on the earth's ecology. In order to solve the energy problem, the development of new renewable clean energy is an important and urgent task. Solar energy is an important renewable energy source and the only inexhaustible clean energy source available...

Problems solved by technology

[0007] When the ordinary polarizing element receives the incident light and realizes the polarization function, most of the incident light will be lost through reflection or other forms, which will cause a large waste of energy

For example, in the liquid crystal display (LCD) technology that is most used today, since the backlight in the LCD needs to be polarized to work, but about 75% of the light energy in the polarized original will be reflected and other forms can not be output eventually, lead to a huge waste of light source
