Balancing electrical and optical losses for efficient 4-terminal Si-perovskite solar cells with solution processed percolation electrodes

The unprecedented rise in efficiency of perovskite-based photovoltaics has sparked interest in semi-transparent devices, particularly for tandem structures. Despite promising reports regarding efficiency and reduced parasitic absorption, many devices still rely on processes from the gas phase, compromising both applicability and cost factors. Here, we report all-solution perovskite solar cells with improved infrared transparency ideally suited as top-cells for efficient multi-junction device configurations. We demonstrate the functionality of copper(i) thiocyanate as antireflective layer and as selective contact between the transparent conductive oxide and the perovskite. This concept allows us to fabricate an opaque device with steady state efficiency as high as 20.1%. By employing silver nanowires with robust environmental stability as the bottom electrode, we demonstrate different regimes of device performance that can be described through a classical percolation model, leading to semi-transparent solar cells with efficiencies of up to 17.1%. In conjunction with the implementation of an infrared-tuned transparent conductive oxide contact deposited on UV-fused silica, we show a full device average transmittance surpassing 84% between 800 and 1100 nm (as opposed to 77% with PEDOT:PSS as the selective contact). Finally, we mechanically stacked optimized perovskite devices on top of high performing PERL and IBC silicon architectures. The measured imputed output efficiency of the 4-terminal perovskite-silicon solar cell was 26.7% and 25.2% for the PERL-perovskite and IBC-perovskite, respectively.

A solar cell sensitized with three different dyes

Construction of a semiconductor – dye heterostructure of the configuration n-TiO2/D1/p-CuSCN/D2/p-CuSCN/D 3/p-CuSCN. (n-TiO2 is the nanocrystalline TiO2 film deposited on conducting glass, p-CuSCN = ultra-thin (?2 nm) layers of Cu(I) thiocyanate, p-CuSCN = thick layer of p-CuSCN, D 1 = Fast Green, D2 = Rhodamine 6G and D3 = Acridine Yellow) is described. It is found that this heterojunction generates photovoltaic response to light absorption by all the three dyes. The mechanism involved is suggested to be transfer of electrons to n-TiO2 and holes to p-CuSCN via tunneling. This technique could be a strategy to broaden the spectral response and enhance the efficiency of dye-sensitized solar cells.

Interfacial N-Cu-S coordination mode of CuSCN/C3N4 with enhanced electrocatalytic activity for hydrogen evolution

Nitrogen/carbon layer coordinated transition metal complexes are the most important alternatives to improve the catalytic performance of catalysts for energy storage and conversion systems, which require systematic investigation and improvement. The coordination mode of transition metal ions can directly affect the catalytic performance of catalysts. Herein, this paper reports that two kinds of Cu-based composites (CuSCN and CuSCN/C3N4) are prepared by in situ controllable crystallization of copper foam (CF) through electropolymerization and calcination. As a comparison, it is clarified that the different coordination modes of Cu1+ ions determine the different catalytic properties. The samples can be switched freely by tuning the electropolymerization period, which leads to different coordination modes of Cu1+ ions dramatically, thus affecting the electrocatalytic performance of composite materials for the hydrogen evolution reaction (HER) in turn. Thorough characterization using techniques, including X-ray photoelectron spectroscopy (XPS) and synchrotron-based near edge X-ray absorption fine structure (EXAFS) spectroscopy, reveals that strong interactions between CuSCN and C3N4 of CuSCN/C3N4 facilitate the formation of subtle coordinated N-Cu-S species, of which electronic structures are changed. Density Functional Theory (DFT) calculations indicate that the electrons can penetrate from CuSCN to N atoms present in C3N4. As a result, CuSCN/C3N4 demonstrates a better catalytic performance than the conventional transition-metal-based electrocatalysts. Besides, CuSCN/C3N4 reflects almost identical hydrogen evolution reaction (HER) activity and stability in an acid electrolyte with Pt/C.

METAL PSEUDOHALIDE COMPLEXES, VI. COPPER(I) AZIDE COMPLEXES WITH SOME PYRIDINE DERIVATIVES, EXAMPLES OF END-TO-END BRIDGING AZIDES
