Open-circuit and short-circuit loss management in wide-gap perovskite p-i-n solar cells

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Feb. 20, 2023

In this work, we couple theoretical and experimental approaches to understand reduce the losses of wide bandgap Br-rich perovskite pin devices at open-circuit voltage (VOC) short-circuit current (JSC) conditions. A mismatch between internal quasi-Fermi level splitting (QFLS) external VOC is detrimental for these devices. We demonstrate that modifying top-surface with guanidinium-Br imidazolium-Br forms a low-dimensional phase n-interface, suppressing QFLS-VOC mismatch, boosting VOC. Concurrently, use an ionic interlayer or self-assembled monolayer p-interface reduces inferred field screening induced by mobile ions JSC, promoting charge extraction raising JSC. The combination n- p-type optimizations allows us approach thermodynamic potential absorber layer, resulting in 1 cm2 performance parameters VOCs up 1.29 V, fill factors above 80% JSCs 17 mA/cm2, addition thermal stability T80 lifetime more than 3500 h 85 °C.

ACS Energy Letters, Journal Year: 2022, Volume and Issue: 7(7), P. 2273 - 2281

Published: June 8, 2022

Monolithic two-terminal (2T) perovskite/CuInSe2 (CIS) tandem solar cells (TSCs) combine the promise of an efficient photovoltaic (PV) technology with simplicity all-thin-film device architecture that is compatible flexible and lightweight PV. In this work, we present first-ever 2T perovskite/CIS TSC a power conversion efficiency (PCE) approaching 25% (23.5% certified, area 0.5 cm2). The relatively planar surface profile narrow band gap (∼1.03 eV) our CIS bottom cell allow us to exploit optoelectronic properties photostability low-Br-containing perovskite top as revealed by advanced characterization techniques. Current matching was attained proper tuning thickness bandgap perovskite, along optimization antireflective coating for improved light in-coupling. Our study sets baseline fabricating TSCs, paving way future developments might push efficiencies over 30%.

Optimizing Crystallization in Wide‐Bandgap Mixed Halide Perovskites for High‐Efficiency Solar Cells

Advanced Materials, Journal Year: 2023, Volume and Issue: 36(17)

Published: Sept. 7, 2023

Wide-bandgap (WBG) perovskites have attracted considerable attention due to their adjustable bandgap properties, making them ideal candidates for top subcells in tandem solar cells (TSCs). However, WBG often face challenges such as inhomogeneous crystallization and severe nonradiative recombination loss, leading high open-circuit voltage (V

Wide-bandgap perovskites play a key role in high-performance tandem solar cells, which have the potential to break Schockley-Queisser limit. Here, 2D/3D hybrid wide-bandgap perovskite was developed using octane-1,8-diaminium (ODA) as spacer. The incorporation of ODA spacer can not only significantly reduce charge carrier nonradiative recombination loss but also inhibit phase separation. Moreover, with synergy effect butylammonium iodide (BAI) surface defect passivator, both stability and device performance were further improved. Compared control inverted VOC 1.16 V PCE 18.50%, optimized PSCs based on processed exhibit superior high 1.26 champion 22.19%, is record efficiency for (Eg > 1.65 eV).
