As an alternative to single crystal silicon photovoltaics, thin film solar cells have been extensively explored for miniaturized cost-effective photovoltaic systems. Though the fight to gain efficiency has been severely engaged over the years, the battle is not yet over.
Thin film solar cell examples covered in this review are mainly of the following four categories: polycrystalline inorganic [Cu (In,Ga) (S,Se) 2 (or CIGSSe for short), and Cu 2 ZnSn (S,Se) 4 (or CZTSSe)], amorphous silicon (a-Si), organic photovoltaics (OPV) and organic-inorganic halide perovskite (perovskite) and etc.
GaAs thin film solar cells have the natural potential to achieve excellent solar energy absorption and high photoelectric conversion efficiency.
It has been widely used in solar farms and building roofs. This, however, is not suitable for integrated photovoltaic, such as windows and facades, nor for electronic devices that require flexibility and transparency. Therefore, thin film solar cells emerged and have attracted increasing attentions.
The device achieved a certified power conversion efficiency of 12.8% and was stable for >1000 h in ambient air under full sunlight . Fig. 51.

CdTe thin film solar cells grew out of these II-VI semiconductor beginnings, in-parallel with CdS efforts at General Electric and the US Air Force, as Loferski [52] had realized that the CdTe bandgap was well-matched to the solar spectrum. Also, CdTe could be doped both n- and p-type – a factor that has not received as much attention in the PV context.
