To increase energy demand, reliability, and increasing efficiency, thin-film solar cells get the main focus. Various types of solar cell like (Cu(In,Ga)Se2 (CIGS), Cadmium telluride (CdTe) and copper zinc tin sulfide (CZTS) based absorber compound now eliminated by CTS (Cu2SnS3) for different reason like toxicity, shortage and structural complexity. Focus on CTS is increasing because it is nontoxic and it is environmentally friendly. CTS-based solar cell's power conversation efficiency increases and 30% theoretical efficiency indicates it's developing sign. For analyzing the synthesis property, X-ray diffraction (XRD), Raman, Energy Dispersive X-ray (EDX), X-ray fluorescence (XRF) techniques are used. For the synthesis of thin-film solar cells like CTS, different physical methods are used among all sputtering methods. The electron beam evaporation vacuum evaporation method has exposed better efficiency and high product quality and reliability. Additionally, the composition, variation of thickness, structural defects, and elemental composition make the absorber layer's quality affect the performance. This paper has discussed the annealing treatment of CTS-based solar cell synthesis, and it's essential to improve the thin film properties of thin films. This paper describes the reason for efficiency reduction also the scope for future research.
