Characterizing Fill Factor Limitations in Perovskite-Silicon Tandem Solar Cells
Yueming Wang, Nan Sun, Chris Dreessen +4
Perovskite-silicon tandem technology has exceeded the single junction theoretical efficiency limit. However, there is still distance to the thermodynamic limit mainly caused by the…
How nanotextured interfaces influence the electronics in perovskite solar cells
Dilara Abdel, Jacob Relle, Thomas Kirchartz +6
Perovskite solar cells have reached power conversion efficiencies that rival those of established silicon photovoltaics. Nanotextures in perovskite solar cells scatter the incident…
Understanding the fill-factor limit of organic solar cells
Huotian Zhang, Jun Yuan, Tong Wang +14
Although the power conversion efficiencies of organic solar cells (OSCs) have surpassed 20%, they still lag behind commercial inorganic solar cells and emerging perovskite solar ce…
Determination of Electron Extraction in Semiconductor Photoanodes: Steady-state and Small-perturbation Response
Paola Ragonese, Chiara Maurizio, Boris Kalinic +2
This work develops an analytical model to consistently interpret the steady-state and small-perturbation response (both in the time and frequency domain) of photoanodes for solar w…
Transport resistance dominates the fill factor losses in record organic solar cells
Chen Wang, Roderick C. I. MacKenzie, Uli Würfel +4
Organic photovoltaics are a promising solar cell technology well-suited to mass production using roll-to-roll processes. The efficiency of lab-scale solar cells has exceeded 20% an…
Deriving mobility-lifetime products in halide perovskite films from spectrally- and time-resolved photoluminescence
Ye Yuan, Genghua Yan, Samah Akel +2
Lead-halide perovskites are semiconductor materials with attractive properties for photovoltaic and other optoelectronic applications. However, determining crucial electronic mater…
