Etch resistant Zn1-xMgxO alloys as an e'-acceptor for dye sensitized solar cells
Author(s):Meing, Erich; Brenner, Thomas; Collins, Reuben T.; Furtak, Thomas E.
In DSSCs, dyes are used to photosensitize a nanoporous electrode, most commonly TiO2. Light excites the dye, which then transfers an electron to the metal oxide electrode. The electron then travels to the conducting contact ...
Developing a process for studying annealing effects on mobilities in silicon quantum dots
Author(s):Adachi, Eleanor; Airuoyo, Idemudia John; Krishna, Lakshmi; Collins, Reuben T.
Modelling thin-film transistors for understanding material properties and improving electronic device performance
Author(s):Schenken, William K.; Airuoyo, Idemudia; Collins, Reuben T.; Colorado School of Mines. McBride Honors Program
Format:journals (periodicals); research (documents)
As new materials continue to develop through theoretical and experimental findings, it is desirable to have a reliable method of testing the materials to better understand their unique properties. Reliable computer modelling ...
Optical spectroscopy of hybrid organic/inorganic solar cell materials
Author(s):Cruz, Jose; Chen, Gang; Otnes, Gaute; Kendrick, Chito; Furtak, Thomas E.; Collins, Reuben T.
Although global energy demands are satisfied by fossil fuels, environmental sustainability is not possible. Due to a need for clean, renewable energy resources, we explored using inorganic photovoltaics as a primary resources ...
Raman characterization of ZnO and Si nanowires
Author(s):Whalen, Jessica; Collins, Reuben T.; Furtak, Thomas E.
Organic Photovoltaics (OPVs) have gained favor recently for low production cost and potential for roll-to-roll flexible substrates. Though efficiency is fundamentally less than commercial PVs, low production temperature ...
Simulation of silicon-based solar cells using finite element analysis (FEA)
Author(s):Schenken, Will; Airuoyo, Idemudia; Collins, Reuben T.
Amorphous silicon (a-Si) and crystalline silicon (c-Si) are some of the most commonly used materials in modern solar cells due to their abundance, inexpensiveness, and performance in photovoltaics. New designs are being ...
Incorporation of silicon nanoparticles into silicon based solar cells
Author(s):Grovogui, Jann; Kendrick, Chito; Collins, Reuben T.
In this project, silicon based solar cells were developed using active layers that consisted of Amorphous Silicon as well as Silicon Nanoparticles (Silicon Quantum Dots). The ultimate goal of this project was to fabricate ...
Raman spectroscopy of silicon quantum dots
Author(s):Kurchin, Rachel; Kendrick, Chito; Collins, Reuben T.; Furtak, Thomas E.
Silicon quantum dots are synthesized and studied extensively by REMRSEC, but they have not thus far had a fast and reliable way to characterize them. In this work, Raman spectroscopy is employed to study dots in varying ...
Successive ionic layer adsorption and reaction for organic/inorganic interfaces
Author(s):Hunt, Heather; Collins, Reuben T.; Furtak, Thomas E.
Zinc oxide is a promising material for use in organic electronics, particularly organic photovoltaics (OPVs). ZnO has a large band gap around 3.3 eV, has a high electron mobility, is non-toxic, and can be processed using ...
Characterization of amorphous silicon and silicon nanoparticle films using variable angle spectroscopic ellipsometry
Author(s):Valentine, Clare; Klafehn, Grant; Airuoyo, Idemudia; Kendrick, Chito; Furtak, Thomas E.; Collins, Reuben T.
