In an effort to diminish the cost of perovskite solar cells (PSCs) with regard to hole transport materials (HTMs), we employed an easily attainable condensation route to synthesize a cheap and efficient HTM. Using a newly engineered small organic molecule, N,N '-(naphthalene-1,5-diyl)bis(1-(2,3-diphenylquinoxalin-6-yl)-1-phenylmethanimine), coded as BEDN, the power conversion efficiency (PCE) reached 17.85%, comparable to that of the state-of-the-art HTM spiro-OMeTAD (19.50%). The BEDN's estimated cost is 1.38 ($ per g), which is considerably cheaper than spiro-OMeTAD, 92 ($ per g). The low cost and high efficiency are promising in commercialization of perovskite solar cells.

A Transverse Flux High Temperature Superconducting Generator Topology for Large Direct Drive Wind Turbines Keysan, Ozan (2012-01-01) The cost and mass of an offshore wind turbine power-train can be reduced by using high-temperature superconducting generators, but for a successful commercial design the superconducting generator should be as reliable as its alternatives. In this paper, we present a novel transverse flux superconducting generator topology which is suitable for low-speed, high-torque applications. The generator is designed with a stationary superconducting field winding and a variable reluctance claw pole motor for simplifie...
Novel metal assisted etching technique for enhanced light management in black crystalline SI solar cells / Es, Fırat; Turan, Raşit; Department of Chemistry (2015) Photovoltaic (PV) technology needs higher performance - lower cost materials and structures in order to catch the grid parity and become an everyday use power source. The most commonly used material in PV, crystalline silicon, suffers from low absorption due to its indirect band gap nature. In order to overcome this problem, several light trapping structures have been used that increase the path length of photons inside the absorbing body of the device. However, conventional light trapping schemes cannot be...
Construction of self-assembled vertical nanoflakes on CZTSSe thin films Terlemezoğlu, Makbule; COLAKOGLU, T.; Abak, Musa Kurtuluş; Gullu, H. H.; Ercelebi, C.; Parlak, Mehmet (IOP Publishing, 2019-02-01) Cu2ZnSn(S, Se)(4) (CZTSSe) is a promising alternative absorber material to achieve high power conversion efficiencies, besides its property of involving low-cost and earth-abundant elements when compared to Cu(In, Ga) Se-2 (CIGS) and cadmium telluride (CdTe), to be used in solar cell technology. In this study, a novel fabrication technique was developed by utilizing RF sputtering deposition of CZTSSe thin films having a surface decorated with self-assembled nanoflakes. The formation of nanoflakes was invest...
High Stability of Benzothiophene and Benzotriazole Containing Medium Band GapPolymer for Inverted Organic Solar Cell Application Ünay, Hande; Hızalan Özsoy, Gönül; Toppare, Levent Kamil; Çırpan, Ali; Alturk Parlak, Elif (2015-05-11) The improvement of polymer solar cell stability is a challenge for the scientists and has significant implications commercially. In this study, we investigated the stability of a novel P-SBTBDT active material applied in an inverted type solar cell. Detailed stability experiments comprising shelf life, laboratory weathering and outdoor testing were carried out according to ISOS testing guidelines. Shelf life showed that P-SBTBDT solar cells were very stable after 840 h with encapsulation. Although accelerat...
A Nonionic Alcohol Soluble Polymer Cathode Interlayer Enables Efficient Organic and Perovskite Solar Cells Sharma, Anirudh; Singh, Saumya; Song, Xin; Rosas Villalva, Diego; Troughton, Joel; Corzo, Daniel; Toppare, Levent Kamil; Günbaş, Emrullah Görkem; Schroeder, Bob C.; Baran, Derya (2021-01-01) The choice of interfacial materials and their properties play a critical role in determining solar cell performance and stability. For compatibility with roll-to-roll printing, it is desirable to develop stable cathode interface layers (CILs) that can be processed over the photoactive layer using orthogonal solvents. In this study, an n-type naphthalene diimide core and oligo (ethylene glycol) side-chain-based conjugated polymer is reported as a universal, efficient CIL for organic and perovskite photovolta...
