A Detailed Evaluation of Charge Recombination Dynamics in Dye Solar Cells Based on Starburst Triphenylamine Dyes

Vinayak, M V; Muhammed Yoosuf; Pradhan, S C; Lakshmykanth, T M; Suraj Soman; Gopidas, K R (Royal Society of Chemistry, 2018-01)

Understanding the charge transfer dynamics in dye solar cells (DSCs) is imperative for the development of highly efficient devices. The loss in photocurrent due to recombination can be alleviated by removing holes formed ...
Fine Tuning of Compact ZnO Blocking Layers for Enhanced Photovoltaic Performance in ZnO Based DSSCs: a Detailed Insight Using Beta Recombination, EIS, OCVD and IMVS Techniques

Swetha, S; Suraj Soman; Pradhan, S C; Narayanan Unni, K N; Peer Mohamed, A; Nair, B N; Hareesh, U S (Royal Society of Chemistry, 2017-12-15)

The electron–hole recombination and back electron flow at the conducting oxide–mesoporous film interface in dye-sensitized solar cells (DSSCs) are addressed primarily by the use of pre-blocking layers. Herein, the effects ...
Molecular systems for solar H-2: Path to a renewable future

Suraj Soman (Taylor & Francis, 2015)

Driving the global energy system into a sustainable path is progressively becoming a major concern and worldwide policy objective. Fossil fuels serve as the primary energy source for most of the world's energy requirements. ...
Stibnite Sensitized Hollow Cubic TiO2 Photoelectrodes for Organic-Inorganic Heterojunction Solar Cells

Ganapathy, V; Zhang, K; Suraj Soman; Nansra, H; Park, J H (Elsevier, 2017-11-15)

Enhancing power conversion efficiency in organic-inorganic heterojunction solar cells faces several serious hurdles. Although standard TiO2 nanoparticles-based heterojunction solar cells are moderately efficient, the TiO2 ...
Strategies for optimizing the performance of carbazole thiophene appended unsymmetrical squaraine dyes for dye-sensitized solar cells

Suraj Soman; Rahim, M A; Lingamoorthy, S; Suresh, C H (Royal Society of Chemistry, 2015)

Unsymmetrical squaraine dyes (CTSQ-1 and CTSQ-2) with carbazole thiophene donor units were synthesized, characterized and used as sensitizers in dye-sensitized solar cells (DSSCs). These squaraines exhibited intense ...
Synthesis and Isotope Effects on the Excited State Properties of N^N Bound [Ir(polypyridyl)2Cl2]PF6 Complexes

Suraj Soman; Younis, H M; Browne, W R; Vos, J G; Pryce, M T (Wiley, 2017-12-22)

A versatile approach to the preparation of [Ir(LL)2Cl2](PF6) type complexes is reported, in which LL is an N^N bound polypyridyl ligand [X2bpy, X2phen, where X = H-, CH3-, (CH3)3C-, or phenyl-, and bpy = 2,2′-bipyridyl, ...
