Herein, we studied the use of two different Self Assembled Monolayers (SAMs) made semiconductor hole transport organic molecules to replace most common p-type contact, PEDOT:PSS, in PiN methyl ammonium lead iodide perovskite solar cells (PSCs).
We present a comparative study between series of well-known semiconductor polymers, used in efficient organic solar cells as hole transport materials (HTM), and the state-of-the art material perovskite cells: spiro-OMeTAD. The observed differences cell efficiencies are studied depth using advanced photoinduced spectroscopic techniques under working illumination conditions. have that there is no correlation highest occupied molecular orbital (HOMO) energy levels semiconductors measured...
We report organic photovoltaic devices in which the standard ITO transparent electric contact has been substituted by lower cost ultrathin metallic electrodes. Solution and vacuum processable n p-type semiconductors provide electrode with rectifying behavior of diode. are this way able to invert built-in field at wish make device deliberately either top or bottom sensitive same efficiency depending on application. Taking advantage these new generation electrodes we furthermore fill factors...
In this work, we analyze the carrier recombination kinetics and associated charge density in methylammonium lead iodide perovskite (MAPI) solar cells that use mesoporous TiO2 as selective contact (m-MAPI) flat (without TiO2, f-MAPI), which are most common device architectures for cells. The of PIT-PV (photoinduced transient photovoltage) L-TAS (laser absorption spectroscopy) showed devices cannot reach efficiencies close to 19% there is a slow component photovoltage decay corresponds pathway...
The combination of halide salts with polyfluorene used as the buffer cathode in organic solar cells greatly improves photovoltaic performance best power conversion efficiency being 11%.
In the urgent quest for green energy vectors, generation of hydrogen by water splitting with sunlight occupies a preeminent standpoint. The highest solar-to-hydrogen (STH) efficiencies have been achieved photovoltaic-electrochemical (PV-EC) systems. However, most PV-EC water-splitting devices are required to work at extreme conditions, such as in concentrated solutions HClO4 or KOH under highly solar illumination. this work, molecular catalyst-based anode is incorporated first time...
We report the synthesis of a solution-processable, dodecyloxyphenyl-substituted azafullerene monoadduct (DPC59N) and its application as electron acceptor in bulk heterojunction organic solar cells (BHJ-OSCs). Due to relatively strong absorption visible light, DPC59N outperforms PC60BM respect short circuit current (JSC) external quantum efficiency (EQE) blends with donor P3HT.

A tandem solar cell device whose sub-cells are fabricated exclusively from small molecules (SMs) through both solution-processed and vacuum-processed deposition techniques is described. The front sub-cell's active layer consists of a bulk heterojunction (BHJ) DPP(TBFu)2:PC70BM while the back has typical bilayer structure employing 2,4-bis[4-(N,N-diisobutylamino)-2,6-dihydroxyphenyl] squaraine (SQ) donor C60 acceptor.
Two new perylenediimides (PDIs) have been developed for use as electron acceptors in solution-processed bulk heterojunction solar cells. The compounds were designed to exhibit maximal solubility organic solvents, and reduced aggregation the solid state. In order achieve this, diphenylphenoxy groups used functionalize a monomeric PDI core, two dimers bridged with either one or thiophene units. photovoltaic devices prepared using monomer conjunction PTB7, it was found that formation of...
