A commercialized system (XPQY-EQE, Guangzhou Xi Pu Optoelectronics Technology Co., Ltd.) equipped with an integrated sphere (GPS-4P-SL, Labsphere) and a photodetector array (S7031-1006, Hamamatsu Photonics) was used to analyze the lifetime, EL spectra and EQE of the PeLEDs. The test parameters were set as follows: area: 0.08 cm−2; target wavelength: 810 nm; bias voltage: 0–4 V; rate: 0.05 V s−1. An SS-F5-3A solar simulator (Enli Technology Co., Ltd.) was used to measure the current density–voltage (J-V) characteristics of the PV performance in the glove box using a computer-controlled Keithley 2400 sourcemeter under a simulated AM 1.5 G solar illumination (100 mW cm−2).

The influence of droop related to the carrier density and internal electric field in QWs having different dbarrier are analyzed through various experiments. A source meter (Keithley 2400) was used for current injection. We used the integrated sphere with a fiber-coupled radiometrically calibrated spectrometer to measure the electrical and the optical properties of the LED operation under current injection. The detection of output power were performed by an array charge coupled device (Hamamatsu, S7031-1006, back-thinned CCD array). The L-I curve is measured in a current range of below 150 mA at room temperature. For temperature-dependent electrical experiments, the LED samples were mounted in a closed-cycle cryostat, and temperature was varied from 150 to 300 K. To carry out the time-resolved PL experiment, a mode-locked Ti:sapphire laser (Coherent, Chameleon Ultra II) was used with double frequency. The wavelength, width, and repetition rate of the pulse laser were 375 nm, 200 fs, and 200 kHz, respectively. A streak camera (Hamamatsu, C7700-01) was employed to measure the decay lifetime.

For the analysis of the optical properties, photoluminescence measurements were carried out using a 325 nm He-Cd laser. In addition, CL spectra and images were obtained using a monochromator and charge coupled device detector (Mono4, Gatan) attached to a field emission scanning electron microscope (XL30s, Philips). A source meter (Keithley 2400) was used for current injection. We used the integrating sphere with a fiber-coupled radiometrically calibrated spectrometer to measure the electrical and optical properties of the LEDs under current injection. Output power detection was carried out using an array charge coupled device (Hamamatsu, S7031–1006, back-thinned CCD array). FDTD simulations (Lumerical) were utilized to analyze the differences in light extraction between samples.

Morphologies of the perovskite films were imaged with a scanning electron microscope (SEM, FEI Apreo LoVac). The crystal structure was characterized by Bruker D8 Advance X‐ray diffractometer (XRD) with Cu Kα radiation at 40 kV and 40 mA. PL lifetime was measured by the time‐correlated single photon counting method with an Edinburgh Instruments FLS980 fluorescence spectrometer. The excitation source used was a picosecond pulsed diode laser at 532 nm.
The current density‒voltage (J‒V) curves of PSCs were recorded using a Keithley 2400 source measurement unit and a Newport solar simulator (ORIEL‐SOI3A) with an AM1.5G spectrum. All of flexible photovoltaic devices were measured in the flatten state. The light intensity was adjusted to 100 mW cm−2 using standard Si cell (91150V). Both forward and reverse scans were measured with the scanning speed of 0.15 V s−1. The EQE spectra were measured in DC mode on a spectrum corresponding system (Enlitech QE‐R), calibrated by Si reference solar cell.
The EL spectrum and ERE of the perovskite LED were recorded simultaneously by a commercialized system (XPQY‐EQE‐350‐1100, Guangzhou Xi Pu Optoelectronics Technology Co., Ltd.) that is equipped with an integrated sphere (GPS‐4P‐SL, Labsphere) and a photodetector array (S7031‐1006, Hamamatsu Photonics).

The UV-visible absorption spectra of pure and treated Hb were measured with the purpose to clarify the liganded status of the heme group under the specified conditions. A broadband light source (Energetiq EQ99-FC, Ocean Optics Inc., USA) and a TEC-cooled spectrometer (QE65Pro, Ocean Optics, Inc., USA) equipped with a FFT-CCD image sensor (S7031-1006, Hamamatsu) were used to acquire the UV-visible absorption spectra with a spectral resolution of 0.8 nm. For each UV-visible absorption measurement, 30 μL of each sample was diluted with 3 mL of DI water and measured in a quartz precision cell with an optical path of 10 mm (Hellma GmbH &Co., Germany). The acquisition time for each spectrum was kept at 100 ms. Oxygen gas of ultrahigh purity was introduced into the quartz cell and constantly purged for at least 10 minutes before the spectroscopic characterization.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
