Charge Photogeneration and Recombination in Mesostructured CuSCN-Nanowire/PC70BM Solar Cells

Fullerene-based materials are widely used as electron acceptors in organic bulk-heterojunction solar cells; yet, they have rarely been used as the only photoactive component due to their low absorbance and limited charge generation efficiency. However, blending the wide-bandgap p-type material copper (I) thiocyanate (CuSCN) with [6,6]-phenyl-C71-butyric acid methyl ester (PC70BM) leads to the formation of a unique mesostructured p-n like heterointerface between CuSCN and PC70BM and solar cells with a power conversion efficiency (PCE) of up to 5.4%. Here, we examine in detail the reasons for the surprisingly good device performance and elucidate the charge photogeneration and recombination mechanisms in CuSCN-based devices with PC70BM as the exclusive light-absorbing material. Our studies clearly demonstrate that a substantial fraction of the photocurrent in the CuSCN-based devices results from improved dissociation of fullerene excitons and efficient charge transfer at the CuSCN:PC70BM interface combined with reduced geminate and nongeminate charge recombination losses. Our results have implications beyond the fullerene-based devices studied here, as they demonstrate that careful selection of a mesostructured p-type transparent semiconductor paves the path to a new type of efficient single photoactive material solar cells.

A comparative study of interface engineering with different hole transport materials for high-performance perovskite solar cells

In recent years, perovskite solar cells (PSCs) are performing remarkably with efficiency more than 20%. Performance can further be improved by controlling charge transfer and recombination at electron transport material (ETM)/absorber and absorber/hole transport material (HTM) interfaces which ultimately define conduction band offset (CBO) and valence band offset (VBO). Therefore, it is worthwhile to investigate optimum band offset to get efficient PSCs. Spiro-MeOTAD is organic HTM commonly used in PSCs while CuI, CuSCN and Cu2O are inorganic HTMs which may replace spiro-MeOTAD due to their low cost and stability. In this paper, device simulation approach is used to analyze the effect of CBO, VBO and interface defect density (Nt) on the performance of PSCs for spiro-MeOTAD as organic HTM and its detailed comparison is made with Cu-based inorganic HTMs to get better insight about the best inorganic HTM. The device simulation shows that CuI has the best PCE of 22.69% when CBO and VBO is set to be +0.2 eV and 0 eV respectively at Nt of 1 ¡Á 1015 cm?3. The results indicate that Cu-based inorganic HTMs are efficient as well as stable HTMs and can be used towards commercializing the PSCs.

Synthesis, crystal structure, and characterization of a novel supramolecular coordination polymer [Cu(Pcba)3]n

The authors present a novel compound [Cu(Pcba)2]n synthesized from the reaction between copper(I) thiocyanate and the ligand Pcba (Pcba = 2-pyrazine carboxylic acid), which exhibits a one-dimensional structure and has been characterized by Xray crystallography. In the process of synthesis, copper(I) ion has been oxidized into copper(II). This compound crystallizes in monoclinic, space group P2 (1)/c with cell parameters of a = 5.0387(4) A, b = 15.3317(13) A, c = 7.0720(6) A, beta = 106.63(0). The central ion Cu(II) is six-coordinated in a typical hexahedral geometry by four oxygen atoms and two nitrogen atoms in Pcba. Except chelating with two Pcbas, each central ion Cu(II) is extended to form one-dimensional linear structure through Pcba as the bridge. This compound was further characterized with IR spectra, fluorescence properties, UV-vis properties, and thermal analysis. Copyright Taylor & Francis Group, LLC 2013.
