AB  - This work utilizes organic photovoltaics (OPV) for indoor applications, such as powering smallelectronic devices or wireless connected Internet of Things. Three representative polymerbasedOPV systems, namely, poly(3-hexylthiophene-2,5-diyl), poly[N-90-heptadecanyl-2,7-carbazole-alt-5,5-(40,70-di-2-thienyl-20,10,30-benzothiadiazole)], and poly[[4,8-bis[(2-ethylhexyl)oxy]-benzo[1,2-b:4,5-b0]dithiophene-2,6-diyl][3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl]],were selected as the donor materials in blend with fullerene derivatives for comparison under lowlight level condition using fluorescent lamps. PCDTBT based devices are found to be the best performingsystem, generating 13.9 lW/cm2 corresponding to 16.6% power conversion efficiency at300 lx, although PTB7 based devices show the highest efficiency under one sun conditions. Thishigh performance suggests that OPV is competitive to the other PV technologies under low lightcondition despite much lower performance under one sun condition. Different properties of thesedevices are studied to explain the competitive performance at low light level. A low energyconsuming method for maximum power point tracking is introduced for the operation of the OPVdevices. Finally, a 14 cm  14 cm OPV module with 100 cm2 active area is demonstrated for realapplications. These findings suggest that OPV, in particular, PCDTBT based devices, could be apromising candidate for indoor applications.
