Organic–Inorganic Copper (II)‐Based Perovskites: A Benign Approach toward Low‐Toxicity and Water‐Stable Light Absorbers for Photovoltaic Applications

“…As the performance of PSCs can be improved by employing novel strategies such as using different electron/hole transport layers, we employed mesoporous zinc oxide (ZnO) as an electron transport layer and developed PSC devices with two different light absorbers (C 6 H 4 NH 2 CuBr 2 I and C 6 H 4 NH 2 CuCl 2 I). The obtained PCEs for the fabricated devices are higher compared to the reported ones (Table ) …”

“…The CV curves for C 6 H 4 NH 2 CuBr 2 I and C 6 H 4 NH 2 CuCl 2 I are presented in Figure A,B, respectively. The conduction band energy ( E CB ) was determined by employing Equation according to the reported literature where E red is the onset reduction potential.…”

“…Furthermore, Elseman et al [22] incorporated mesoporous layers for effective charge extraction and obtained 0.99% efficiency for (CH 3 NH 3 ) 2 CuCl 2 Br 2 ‐based PSC devices. More recently, Li et al prepared a new light absorber (C 6 H 4 NH 2 CuBr 2 I) and developed Pb‐free PSCs with TiO 2 as the electron transport layer. The PSC devices showed a PCE of 0.46% with a good photocurrent density of 6.2 mA cm −2 .…”

A (CH3NH3)3Bi2I9 Perovskite Based on a Two‐Step Deposition Method: Lead‐Free, Highly Stable, and with Enhanced Photovoltaic Performance

“…The recorded CV data is presented in Figure S8 (A). The conduction band energy (E CB ) was calculated using equation (2) reported elsewhere …”

“… Schematic diagram showing the (CH 3 NH 3 ) 3 Bi 2 I 9 based PSC device architecture (a) and energy‐level diagram (b) The energy‐level values were taken from the literature to illustrate the working of PSCs . The energy‐level value for MBI was determined by CV+UV/Vis spectroscopy …”
