Determination of Free Charge Carrier Luminescence and Quasi‐Fermi Level Separation in Organic Solar Cells via Transient Photoluminescence Measurements

“…This is most likely a consequence of a finite parallel resistance that limits the voltage severely toward lower intensities. [ 48 ] A more detailed analysis is however beyond the scope of this work.…”

Holistically Optimizing Charge Carrier Dynamics Enables High-Performance Dye-Sensitized Solar Cells and Photodetectors

“…In spite of the illumination intensity further being reduced to ∼0.3 mW/cm 2 (1000 lux), the modified devices still feature a remarkable PCE of 28.64%, which is still higher than that of control ones [20.15%, Figure S16, J – V curves of DSSCs based on the TiO 2 photoanode or TiO 2 –Ti 3 C 2 T x photoanode under dim light with an intensity of ∼0.3 mW/cm 2 (1000 lux); Table ]. The superior photovoltaic performance of modified devices should be ascribed to their synergistic effect of low charge carrier generation and reduced charge carrier recombination and presents high potential as indoor photovoltaics for the application of IoT. , Besides, the modified devices also present superior light stability than control ones (Figure S17, device stability of encapsulated DSSCs based on the TiO 2 photoanode and TiO 2 /Ti 3 C 2 T x photoanode), indicating the great potential of modified devices in the practical application.…”

Voltage losses in indoor light harvesting organic photovoltaic devices: a case study of green solvent processed PM6/IT-4Cl devices

“…The development of methods to process OPV devices using green solvents has further accelerated the industrialization of this technology. [18][19][20] Despite this, many donor-acceptor systems with desired absorption spectra are expected to perform poorly under indoor LED illumination due to limited V OC . 21,22 For instance, the green solvent-processible blend PM6/IT-4Cl has an absorption onset of less than 800 nm, aligning with the spectrum of typical white LED lights.…”
