“…9,10 In order to improve solar cell efficiency, one parameter that needs to be optimized is the carrier mobility within the TCO. 11,12 To further improve the carrier mobility of FTO thin films, a fundamental understanding of the electron scattering mechanisms is a prerequisite condition. Four different electron scattering mechanisms are reported to account for the electrical properties of TCO thin films: grain boundary (GB) scattering, phonon scattering, ionized impurity scattering, and twin boundary scattering.…”

“…Table 2 The cause of the low FF is attributable to the high series resistance, 10 Ω.cm 2 compared with 2.2 Ω.cm 2 for the best device on ASG. Only having a front contact on one side of the device will cause a larger resistance contribution from the AZO although a previous study on the effect of TCO resistance and device configuration would indicate that this would only contribute in the region of 3 Ω.cm 2 to the series resistance with the AZO sheet resistance of 10 Ω/ [17]. The silver paint applied to the AZO front contact was also suspected of introducing a high contact resistance thus contributing to the unusually high series resistance.…”

“…En este proceso se consideran procesos de sublimación de espacio cerrado, además de métodos químicos y electroquímicos [5], [19]. No obstante, cabe resaltar que los óxidos conductores transparentes desempeñan un papel fundamental dentro de la eficiencia de las células solares de película delgada, ya que ofrece el denominado "contacto frontal", el cual permite que la radiación solar involucrada en la célula subyacente lleve la electricidad generada hacia el circuito externo; no obstante, este contacto frontal debe ser acoplado con muy baja resistencia eléctrica [20]. Esta célula puede proporcionar una respuesta espectral superior para climas húmedos y cálidos con un coeficiente de temperatura superior [17].…”
