非晶硅与晶硅太阳电池在太阳能光伏发电应用中热性能的研究

对在北京地区屋面上固定角度安装(目前光伏发电应用中最常见的安装形式)的非晶硅和多晶硅太阳电池组件进行了近二年的数据采集,纪录了北京地区温度数据和太阳电池阵列的实际发电量,分析了它们各自的特点,为用户更为关心的户外使用情况提供了参考依据;认为如果仅从温度特性考虑,是否采用非晶硅替代晶体硅电池在不同地区应有不同考虑,如果再考虑到人们普遍认为的非晶硅电池没有解决的稳定性问题,表面玻璃的非钢化、效率低等其它问题,非晶硅的使用应慎重,不应盲从.同时在使用中不论何种电池都不应忽视组件的通风问题.

STUDY ON TEMPERATURE-DEPENDENCE PERFORMANCE OF AMORPHOUS AND CRYSTALLINE SILICON SOALR CELLS IN PV APPLICATIONS

Owing to the shortage of silicon feedstock and for lowering the cost,the a-Si solar cells have been researched and developed for long time.The PV experts even appeal to using a-Si PV modules instead of crystalline silicon PV mod- ules.The PV modules'performances can be influenced by many factors,such as solar irradiance and temperature etc.In general,the rated power is used to scale the real output power.Two years'data of a-Si and poly-Si PV power generation systems were collected and the characteristics of...
