According to qinghai daily reports, member of Chinese Academy of Sciences li in a recent speech, this paper introduces the latest research progress of polymer photovoltaic solar cell materials. Now use of fossil fuels, he said, is the earth billions of years of accumulated, such as coal is buried in the ground to form the ancient plants, oil is a form of animals buried in the ground, in the next few decades, human will put billions of years of accumulated energy depletion. Consider the next step development of renewable energy, solar energy is one of the most important renewable energy. The sun has enough fuel to continue to drive our solar system in 5 billion, the sun to earth daily energy consumption is 10000 times more than us.
li, there are several kinds of important form of solar energy utilization, solar heat utilization and solar light use, heat utilization include solar water heaters and solar thermal power generation, light use include solar photochemical and light catalysis, solar cells, The solar cell) , the use of solar energy is the most important reaction & ndash; — Plant photosynthesis.
is solar cells convert solar energy directly into electrical energy device, including monocrystalline silicon, polycrystalline silicon solar cell, inorganic semiconductor thin film solar cells, dye sensitized solar cell, perovskite organic/polymer solar cells and solar cells. The key materials of the polymer solar cells including donor, receptor and modified electrode interface layer materials, photoelectric conversion process including absorption and exciton diffusion, exciton charge separation, charge transfer and charge collection.
li: polymer solar cells with device has simple structure, low cost, light weight, and flexible and can be prepared into a translucent devices such outstanding advantages, has important application prospect. The absorption of donor and receptor photovoltaic material complementary and energy level matching is the key to realize high-efficiency polymer solar cells. Side chain project is to improve the performance of photovoltaic donor and receptor material effective means. Polymer solar cells to the stage to the actual application development, reduce the cost of photovoltaic materials and devices, research, and improve the stability of the material and devices is the realization of the rights of the polymer solar cells in the future the key to practical application.
