Abstract

Today, the energy consumption of new technologies, such as mobile phones, has increased, and the availability of recharging technology is very important. Among today's sources of electricity generation, flexible solar cells (FSCs) are promising for a variety of reasons. It is very important to attend to the performance power efficiency of these devices, and the use of durable materials reinforces this feature. New inorganic components with high adsorption coefficients and usability in solar cells have been introduced. These components can layer on flexible substrates, so they can be used in flexible solar devices. Among inorganic components for PV technologies, Cu(In, Ga)Se₂ (CIGSe) and CdTe with outstanding photoelectric performance have practiced rapid expansion. CIGSe solar cells are a promising option for a wide range of commercial applications due to their excellent photovoltaic properties, large tolerance of compositional deviation, and benign grain boundaries. CdTe has demonstrated the highest scalability and reproducibility among thin films so far, as reported by the successful industrial production within the last 10 years. The advantages of the 1D crystal-structural Sb₂Se₃ structure are superior flexibility and high bandgap, but its disadvantages include complex defect chemistry and highly anisotropic carrier transport.
