The polymer-based solar cells (PSCs) are promising due to their simple fabrication procedure, low material cost and flexibility. In recent years, PSCs based on the conjugated polymers as the electron donor materials blended with [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) have been investigated extensively using a single bulk heterojunction (BHJ) device structure. The semiconductivity and solar cell material properties of thiazolo[5,4- d]thiazoles have been investigated previously [1,2]. In the present work, the photovoltaic properties of conjugated poly(triphenylamine-thiazolo[5,4-d]thiazole) (p-TPTT) alternating copolymer dye were investigated. The p-TPTT copolymer is a red colored dye material with a band gap energy of 1.36 eV. Using the weight ratio of 1:3 for the p-TPTT polymer:PC71BM blend, the OPV device performance values were found as Isc=4.10 mA/cm2 , Voc= 0.47 V, FF=29% and PCE=0.55%. The p-TPTT solar cell resulted in the maximum IPCE of 14.5% at 470 nm. Therefore, the new copolymer structure can be considered as a promising organic solar cell dye material.

Terlemezoğlu, Makbule; Parlak, Mehmet; Department of Physics (2019)
Cu2ZnSn(S,Se)4 (CZTSSe) compound is one of the most promising absorber materials for thin film solar cell technology due to the abundance and non-toxicity of its constituents. Besides, CZTSSe has an ideal direct band gap value in the range of 1-1.5 eV and high absorption coefficient (> 104 cm-1) in the visible region, which satisfies the conversion of the maximum amount of energy of the solar spectrum. For this, CZTSSe absorber layer with only a few microns of thickness is sufficient to absorb all the photo...
Fabrication and characterization of PEDOT:PSS hole transport layers for silicon solar cells
Türkay, Deniz; Yerci, Selçuk; Department of Micro and Nanotechnology (2019)
Heterojunction silicon solar cells have gained considerable interest in recent years with the demonstration of record-high device performances. However, these devices are typically based on inorganic layers fabricated at high temperatures under vacuum environment, using toxic precursors. The low temperature budget, non-toxic chemical contents, and wide range of adjustability in physical and electrical properties make poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) a promising candidate a...

Toppare, Levent Kamil; Yaşa, Mustafa; Göker, Seza; Udum, Yasemin; Günbaş, Emrullah Görkem; Çırpan, Ali (null; 2018-07-06)
Inverted organic solar cells have advantages over conventional organic solar cells. Most important advantage is the improved stability of inverted solar cells. In this study, benzodithiophene, quinoxaline and selenophene bearing conjugated polymer was used as donor material in inverted solar cell applications. Device performances were investigated with the device configuration of ITO/ ZnO/ polymer:PC71BM/ MoO3/ Ag. In order to improve device performance, polymer PCBM ratio, active layer thickness, annealing...
PASSIVATION OF SILICON SOLAR CELLS VIA LOW TEMPERATURE WET CHEMICAL OXIDATION

In the development of high efficiency crystalline Si solar cells, decreasing bulk and surface recombination velocities of the minority carriers is vital. As the bulk recombination could be suppressed by enhancing the material quality, the effect of surface recombination on cell performance becomes more dominant. Also, recent studies have revealed that the area under the metal contacted region needs to be passivated to minimize the carrier recombination. The passivation of front and back surface of the cell ...
MoOx/Ag/MoOx multilayers as hole transport transparent conductive electrodes for n-type crystalline silicon solar cells
Akdemir, Ozan; Borra, Mona Zolfaghari; Nasser, Hisham; Turan, Raşit; Bek, Alpan (Wiley, 2020-03-25)
Substitution of highly doped layers with conventional transparent conductive electrodes as carrier collecting and selective contacts in conventional crystalline silicon (c-Si) solar cell configurations is crucial in increasing affordability of solar cells by lowering material costs. In this study, oxide/metal/oxide (OMO) multilayers featuring molybdenum oxide (MoOx) and silver (Ag) thin films are developed by thermal evaporation technique, as dopant-free hole transport transparent conductive electrodes (HTT...
