Photovoltaic devices are the source for future energy where the naturally abundant solar energy is converted into electricity using photoactive materials. An efficient photon management mechanism is essential for achieving high efficiency next generation solar cells. The use semiconducting two dimensional (2D) transition metal dichalcogenide (TMDCs) nanosheets light absorbing layer in modern solar cell is inevitable. Diverse large area synthesis tools to tailor nanosheets and its incorporation in solar cell cover the entire solar spectrum for enhanced photon management. In this review, the case to case use of TMDCs in various photovoltaic devices as an efficient absorber layer has been discussed. Experimental measures to overcome the limitations of pristine TMDC layers due to its atomic layer thickness were also reviewed. It can be seen that, the device performance of the TMDCs based solar cells is showing significant improvement in comparison with conversional silicon based photovoltaics.
