The impact of synthesis techniques on the properties of hybrid perovskite materials for photovoltaic application

Author: Olaleru, S Akin ; Wamwangi, D ; Kirui, JK ; Roro, Kittessa T ; Mwakikunga, Bonex W ; Palaniyandy, Nithyadharseni ; El-Mahallawy, N ; Rashad, N Date: Jul 2020 Hybrid perovskites are organometal halide materials that are attractive to the researchers owing to impressive physical properties like absorption coefficients. Controlled formation of perovskite crystal during the preparation process is key ... Read more
Mechanistic formation of TiO2 nanotubes via anodisation – effect of operating voltage and time

Author: Cummings, FR ; Le Roux, Lukas J ; Hietkamp, S Date: Jul 2008 Titanium dioxide (TiO) nanotubes hold great potential for application in dye-sensitised solar cells for they provide a one-dimensional transport route for generated charge carriers. An investigation is launched into the formation of these ... Read more
Perovskite solar cells: The new epoch in photovoltaics

Author: Olaleru, SA ; Kirui, JK ; Wamwangi, D ; Roro, Kittessa T ; Mwakikunga, Bonex W Date: Jan 2020 Perovskite-based solar cells (PSC) is the fastest growing solar technology to date since inception in 2009. This technology has revolutionized the photovoltaic (PV) community. While it has taken 15–42 years for traditional PV technologies to ... Read more
Photoelectrochemistry of metallo-octacarboxyphthalocyanines for the development of dye solar cells

Author: Mphahlele, N ; Ozoemena, K ; Le Roux, Lukas J ; Mathe, Mahlanyane K ; Nyokong, T ; Cele, LM ; Soji, S ; Kobayashi, N Date: Sep 2011 Significant attention is being paid to dye solar cells (DSCs) as the next generation in solar cell technology for their low cost alternative as compared to solid state solar cells.
