Indoor photovoltaics (IPVs) have attracted great attention due to their potential applicability as a power source to the emerging Internet of Things (IoTs) – low power electronic devices equipped with sensors, actuators, and internet connectivity. Dye-sensitized solar cells (DSSCs) are well known for environmentally friendly and high-efficiency in indoor conditions, as it shows strong absorbance in the visible light range. Considering this context, herein, energy loss factors in DSSCs are thoroughly investigated and the feasible efficiency limits in DSSCs are calculated in outdoor and indoor conditions and compared with the SQ limit of the ideal solar cell. The feasible efficiency of DSSCs at one sun condition is 23.78% at the band gap of 1.34 eV. However, in indoor light conditions, the maximum PCE feasible for DSSCs is 35-41% compared to that of 50-58% for SQ ideal solar cell at the absorber band gap between 1.82-1.96 eV. The possible Jsc and Voc of DSSCs in indoor conditions are in the range of 98-116 μA cm-2 and 0.93-1.41 V, respectable, which are 109-129 μA cm-2 and 1.08-1.55 V, respectively, for SQ ideal solar cells at different illuminance.  Furthermore, DSSCs in indoor conditions could provide a maximum power intensity of ˃ 100 μW cm-2, suggesting the suitability of IDSSCs for activating IoT devices in the smart house.
