The indoor utilization of emerging photovoltaics is promising but power conversion efficiency (PCE) under indoor lighting is still challenging. Dye sensitized solar cell (DSSC) is one of the most excellent options to harvest and convert the artificial indoor light into electricity. In present study, we investigated the indoor performance of N3 sensitized Titania DSSCs under artificial lighting. We observed a substantial improvement in PEC of solar cell.
Under the indoor illumination of 33 mW/cm2, the maximum PCE obtained was 28.21 %. Our findings suggests that the obtained high efficiency N3 sensitized Titania DSSCs under artificial lighting have a good potential application for low power electronic devices for their autonomous operation. Graphical abstract shows the result with glowed LED using three series connected DSSCs.
