New Design Concepts for Inorganic Solar Cells: From Thin Films to Functional Nanostructures: Using a pulsed laser for in-situ growth of semiconductor core-shell nanostructures

Abstract

For many years solar cells were totally inorganic and its design used to be simple. No matter how many junctions you could think about, at the end the interfaces were planar and the configurations followed a stratification of layers. And then, nanotechnology opened a wide variety of possibilities in which the architecture of the solar cells not only changed how solar cells architectures look like, but also, the working principle and materials functionality. In this type of solar cells, we have used a Nd:YAG pulsed laser as a heat local source. Previously, we have impacted in the process of seeding prior to ZnO nanorods growth by an hydrothermal technique [1]. In this approach, we use it for achieving the CdS quantum dot semiconductor harvester and ZnO nanorod electron transport partners in a single, simple and in-situ step.
