Research progress of analysis of laminated solar cells

Source: 2020 - 04 - 06 on clicks, the research progress of laminated solar battery consists of different band gap width of the battery of laminated solar cells can effectively increase the solar energy absorption of incident photon, so as to improve the conversion efficiency. Photoelectric properties are reviewed and the research progress of various laminated photovoltaic equipment, such as composite laminated solar cells, silicon laminated solar cells, polymer laminate pigment intensifying laminated solar cells and solar cells, and puts forward some technical countermeasures to improve solar cell conversion efficiency. In recent years, the solar photovoltaic technology got rapid development. Monocrystalline silicon and polycrystalline silicon solar cells have been commercialized, the solar battery, polymer solar cells and dye sensitized solar cell are also under development. Photovoltaic technology development history, to improve the conversion efficiency of solar cells, need to consider the following two aspects. On the other hand, improve the performance of photovoltaic material and structure of photovoltaic devices, reduce the battery ( 1] Light carrier of all kinds of energy loss. If the different band gap width of the battery pack composite laminated solar cells, and make each battery can absorb match their band gap width of the photon energy, can expand the absorption of sunlight, greatly improve the conversion efficiency. In 1994, Meier [ 23] For the first time put forward the concept of laminated solar cell, and making the initial efficiency of 9. 1% of the laminated batteries, then laminated solar cell research has received eager please note. Especially in recent years, through the development of new materials, the improved process and optimize the structure of the battery, the laminated got steadily improve the efficiency of solar cells. At present, the GaInP/GaAs/GaInNAs three junction solar cells in [ 4] Under the condition of the condenser conversion efficiency reached 43. 5%. In the future, laminated solar cells is expected to become efficient solar cells. Composite were reviewed polymer solar cells, solar cell silicon base pressure, laminated solar cells and dye sensitization laminated solar photovoltaic performance. As the most promising of the third generation solar cells, solar battery is important progress. Main research direction is to improve the conversion efficiency of solar cells, reduce the production cost. In order to further improve the efficiency of energy conversion, need to pay attention to the following several aspects: 1) For the composite laminated solar cells, and need to further improve its tunneling junction characteristics, optimizing the material composition of the battery, produce good current matching, high lattice matching and band gap of composite laminated solar cells. 2) Further optimize the lamina propria of silicon-based laminated solar cell thickness, doping concentration and middle layer material, find the right materials and process parameters to improve the performance of the laminated solar cells; 3) More research on the stability of polymer materials and organic dyes, improve laminated polymer solar cells and the stability of the dye sensitized laminated solar cells. With the development of the laminated solar technology, solar battery is expected to become the mainstream of the photovoltaic industry in the near future.
