Description

A high-performance broadband solar cell material

technical field

The invention belongs to the technical field of battery material preparation, and in particular relates to a high-performance wide-spectrum solar battery material.

Background technique

The shortage of energy has seriously affected people's life and restricted the development of society. Abundant solar energy is an important clean energy, which is inexhaustible, inexhaustible, pollution-free, cheap, and can be freely utilized by human beings. After the first oil crisis, countries competed to carry out research on the application of clean and renewable energy such as solar energy, water energy, and wind energy, especially the most extensive application research on solar energy.

As a kind of green energy, solar energy has no pollution to the environment, and its source is simple, so it can be said that it is inexhaustible within the life span of human beings. Solar energy is not only a one-time energy source, but also a clean energy source. It is abundant in resources, ubiquitous, free of transportation, free to use, and most importantly, has no pollution to the environment. Due to the particularity of solar energy, solar cells have many advantages that other power generation methods do not have: no geographical restrictions, no fuel consumption, large or small scale, great flexibility, no pollution, no noise, safe and reliable, and short construction period , maintenance is simple, and it has the possibility of large-scale application. Therefore, many experts develop solar energy as an alternative energy source, hoping that the sun can benefit mankind. A large part of the solar energy used today is converted by solar cells. Because the solar cell is sensitive to light, it can convert the light energy irradiated on its surface into electrical energy. At present, with the efforts of relevant experts, solar cells have been commercialized and industrialized.

The core part of a solar cell is a p-n junction made of semiconductors. Sunlight shines on the semiconductor p-n junction to form hole-electron pairs. Under the action of the electric field in the p-n junction, the holes flow from the p-region to the n-region, and the electrons flow from the n-region to the p-region. After the circuit is turned on, a current is formed. Because semiconductors have a certain bandwidth, solar cells can only effectively convert photons close to the semiconductor bandwidth and energy hv into electrical energy. Photons with energy less than the bandwidth cannot be absorbed by the battery, while photons with energy greater than the bandwidth have only a part of their energy used by the battery, and the part beyond the bandwidth is converted into heat energy through electron-phonon interactions, resulting in energy loss. More than 99% of the solar radiation spectrum is at a wavelength of 150-4000nm, of which about 50% of sunlight is visible light, and the rest is ultraviolet light or infrared light. Due to the differences in the semiconductor materials used, the external quantum efficiencies of different solar cells are significantly different. But for fixed semiconductor materials, solar cells can only effectively use sunlight of a specific band. At present, even single-junction silicon-based solar cells with a wide spectral response range can only use the energy in the visible light region, so how to effectively use the broad-spectrum energy in sunlight, including ultraviolet and infrared bands, is an important issue in the current solar cell research. subject.
