Current–voltage measurements were carried out in ambient air under AM 1.5G illumination using a self-calibrating Sinus-70 solar simulator (Wavelabs, Leipzig, Germany). An X200 source meter (Ossila, Sheffield, UK) was used to assess solar cell performance (scan speed 100 mV s−1). A mask was employed to confine the active solar cell area to 0.16 cm2. Ambient light characterization was carried out with a Warm White 930 18 W fluorescent tube (OSRAM, Munich, Germany), and a PGSTAT 100 potentiostat (Metrohm Autolab, Utrecht, The Netherlands) was utilized to record the current–voltage characteristics. The lamp spectrum is illustrated in the ESI, Fig. S6.† The stabilized illumination intensity was calibrated with a commercial lux meter (Clas Ohlson, Insjön, Sweden) before measurements. Values of illumination intensity were cross-checked with lux meters from different manufacturers. The entire active photovoltaic area of the devices was used during indoor characterization to mimic diffuse light conditions.

IPCE spectra were recorded with a computer-controlled system comprised of a xenon lamp (Spectra products ASBXE 175), a monochromator (Spectra Products CM110), a LabJack U6 and a potentiostat (PINE AFRDE 5). Measurements were executed after a previously performed calibration with a certified reference solar cell (Fraunhofer ISE). Transmission measurements were performed with a PerkinElmer Lambda 900 spectrometer. Photovoltaic performance was measured by illuminating the samples with AM1.5G sunlight provided by a self-calibrating WaveLabs SINUS-70 solar simulator with UV and IR range extenders while measuring the cell's current-voltage response with an Ossila X200 source meter. Black masking was applied on top of the cell with an aperture of 0.065 cm 2 for filtered and unfiltered PbS CQD back sub-cells and of 0.125 cm 2 for semi-transparent MAPbI 3 solar cells.
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.
