Solar cell as the core unit in photovoltaic power generation system. Its energy conversion efficiency and cost di?rectly affects the application of photovoltaic power generation system. How to improve efficiency and reduce costs is one of the core tasks of photovoltaic technology workers. Conversion efficiency of the solar cell is determined by its output parameters (open circuit voltage,short circuit current and fill factor). According to the analysis on influence of material band gap,life of minority carriers,temperature and parasitic resistance on output parameters,the rule that influence the efficiency of solar cells was obtained. The methods to improve the efficiency of solar cells are proposed. This will have a certain role in the development and applications of solar cells.
