In this study, after giving general information about chalcopyrite solar cells, different production methods, development methods applied to solar cell layers and the status of research conducted around the world are examined. It has been shown that chalcopyrite solar cells can compete with different types of solar cells with an efficiency of 26%. It has been determined that the traditional chalcopyrite structure has been replaced by silver alloyed chalcopyrite structure in recent years. Silver alloying research has shown that the silver alloyed chalcopyrite structure exhibits better grain growth at the same production temperatures compared to the traditional chalcopyrite structure. This has enabled the crystal quality to increase. Additionally, widening the bandgap by silver alloying has contributed to multilayer tandem solar cell studies. The biggest contribution of silver alloying to wide bandgap studies is the ability to control the distribution of gallium in the chalcopyrite structure. Moreover, better efficiency results were obtained because silver alloying reduced recombination and increased the open circuit voltage. It is also very important that transparent and flexible solar cells can be designed with this technology. It is predicted that the future of studies on chalcopyrite solar cells will be shaped by silver alloying. The fact that both flexible and transparent solar cells can be used in areas such as wearable solar cells, building applications and agrivoltaics that can be used in agricultural lands increases the importance of the subject.
