随着光伏技术日益进步,其应用场景愈加细分,一些场景需要使用非平面光伏电池组件以兼顾其功能性与美观需求。基于顶衬碲硒镉薄膜太阳电池结构特点,利用玻璃热弯技术,在常压环境且充保护气体的管式炉中直接对顶衬碲硒镉薄膜太阳电池小面板进行热弯,制备了非平面顶衬碲硒镉薄膜太阳电池小组件,使用I-V测试仪对其热弯前后I-V特性进行了研究。结果表明,热弯温度为610℃时,小组件的VOC、JSC、FF和效率与热弯前相比未见明显衰减,热弯温度为630℃时,小组件仍能保持约10%的光电转化效率。该研究证明,当应用场景需要非平面光伏电池时,通过直接热弯顶衬碲硒镉薄膜太阳电池面板制备非平面碲硒镉太阳电池组件是可行的,这为非平面碲硒镉太阳电池组件产业化提供了一种制备方法。 相似文献

本研究提供了一种高效钙钛矿薄膜太阳能电池柔性组件的封装方法,电池模块包括一个基座,基座上以矩阵形式排列着多个串联和平行的钙钛矿太阳能电池组件,其中每个钙钛矿太阳能电池组件被一个完全透明的底板包围在密封的钙钛矿薄膜中,该底板与高效钙钛矿薄膜太阳能电池的柔性组件是一个密封系统。每个钙钛矿太阳能电池组件被封闭在由底部底板、全透明底板和密封材料围成的密封空间内,其正负级耦合终端使得各个电池组件都是密封的。该封装方法解决了单个钛酸钙电池模块在使用过程中被损坏不易更换的问题,并且具有更好的封装效果。 相似文献

Lithiated layered transitional metal oxide materials of the LiMO2 type and especially LiCoO2 presents interesting specific properties as high energy density, long cycle life and constant discharging properties in a wide range of working conditions as well as a good safety. These properties made these materials excellent candidates as active compounds for high capacity cathode materials for rechargeable lithium batteries. LiCoO2 is the most common lithium storage material for lithium rechargeable batteries, used widely to power portable electronic devices. Operation of lithium rechargeable batteries is dependent on reversible lithium insertion and extraction processes into and from the host materials of lithium storage. In this study, LiCoO2 thin films were prepared by the sol–gel spin coating technique using metal acetate and citric acid as starting materials. Citric acid acts as a chelating agent, which promotes the preliminary reaction between lithium and cobalt and suppresses the precipitation of acetates. The sol–gel method is well known as one of promising thin-film preparation methods, which has good advantages such as low fabrication cost, relatively easy stoichiometry control, high deposition rate and also known as a low-temperature synthesis method for various ceramics. In addition, the crystal phases involved in the thin film can also be controlled by changing the chemical compositions of the sol. The crystallinity, microstructure and electrochemical properties of final films are also studied by XRD, SEM, AFM and galvanostatic charge/discharge cycling test. Films heat-treated under appropriate conditions exhibit high capacity and good crystallinity so those films are considered to be candidates as cathodes for thin-film micro batteries. 相似文献
