The newly developed fiber-shaped solar cells have attracted much interest at both academy and industry owing to their angle-independent collection for incident light. Recently, we have developed a series of high-performance and flexible fiber-shaped solar cells by using the imique carbon nanostructure fiber electrodes. Typically, these solar cells are classified in three types, that is, DSSC, PSC, and perovskite solar cell.

Research on perovskite solar cells is continuing at a furious pace. Reference to the recent reviews in Further Reading section will provide background to this rapidly advancing area of study.

A key issue for perovskite solar cells is the stability of perovskite materials due to moisture effects tmder ambient conditions (134). An improved CHsNHsPbls-xClx perovskite quality with good crystallization and stability by using water has been developed as an additive during the crystal perovskite growth. 

Thus, water additive-based perovskite solar cells present a high-power conversion efficiency of 16% and an improved cell stability under ambient conditions in comparison to previous materials. These findings provide a route to control the growth of crystal perovskites to improve the stability of organic-inorganic halide perovskites (134). 

Moreover, phosphonium halides can be used as an interfacial n-dopant to improve the electrical properties of cathode contacts. Perovskite solar cells incorporating organic halides as processing additives and interfacial modifiers show significant device performance improvement.
