Abstract:
The shortage of traditional energy and environmental pollution become the major problem of restricting the development of economic．So searching for pollution-free resources becomes more and more urgent．As a clean and renewable power source，solar energy gets much more attention．The solar cell is a device converting solar energy directly into electrical energy，also is an effective way to use solar energy．As a kind of green energy，especially in nuclear security problems facing challenges today，solar cells are thought to be the best choice to solve the energy failure and environmental pollution and so on. At present，many countries are drafting long-term solar development plan，and prepare to develop large-scale solar energy in the 21st century．This paper briefly introduces the current status of solar cells , including monocrystalline silicon solar cells，polycrystalline silicon solar cells，thin film solar cells and so on，comparing and discussing all kinds of its technology，the efficiency of conversion from aspects and preparation methods and their properties Of the advantages and disadvantages，and the trends in the development of that is also presented．
