摘　　要：采用反打工艺将光伏组件与装配式混凝土一体化成型,并对制备的预制混凝土光伏墙板的性能进行研究。结果表明,光伏背板材料能满足耐碱和拉拔性能要求,光伏板能够与混凝土固定粘接且不被腐蚀;光伏组件发电时,自身温升受天气影响较大,同时受混凝土蓄热的不利影响,光伏墙板1年间的最高测试温度为60.4℃,通过PVsyst软件模拟,得到光伏组件的光电转换效率相应下降8%,基本不影响正常使用;应用于立面的光伏墙板在实际发电时受太阳高度角和有效辐照量的影响,光伏组件的单位面积发电量在夏季最低,冬季最高,增幅约37%。The photovoltaic(PV)modules were integrated with the assembled concrete using a reverse molding process and the performance of the prepared prefabricated concrete PV facades were studied.The results showed that PV backsheet can meet the requirements of alkali resistance and tensile performance tests,proving that the PV panel can be fixedly bonded to the concrete and not corroded;when the PV module works,the temperature of its own was mainly influenced by the weather,while it was adversely affected by the heat storage in the concrete,the maximum temperature of the prefabricated concrete PV facades throughout one year was 60.4℃,which was in line with the standard,and it was obtained through PVsyst that the efficiency of PV module's photovoltaic conversion decreased by 8%,which basically did not affect its normal use.Meanwhile,when the prefabricated concrete PV facades applied to the facade and generated electricity,the power output per unit area of PV modules was lowest in Summer and highest in Winter,with an increase of approximately 37%due to solar altitude angle and effective irradiance.
