Improving Perovskite Solar Cells: Insights From a Validated Device Model

2017

To improve the efficiency of existing perovskite solar cells (PSCs), a detailed understanding of the underlying device physics during their operation is essential. Here, a device model has been developed and validated that describes the operation of PSCs and quantitatively explains the role of contacts, the electron and hole transport layers, charge generation, drift and diffusion of charge carriers and recombination. The simulation to the experimental data of vacuum-deposited CH3NH3PbI3 solar cells over multiple thicknesses has been fit and the device behavior under different operating conditions has been studied to delineate the influence of the external bias, charge-carrier mobilities, e…

Solid state ionics and optical materials technology for energy efficiency, solar energy conversion, and environment control

1991

The fundamental electronic properties (including optical) of a solid are determined by the character of the interaction between its ionic and electronic subsystems. The state of the ionic subsystem can be changed persistently and reversibly by an external stimulus (current, light). The pertinent ion-controlled phenomena in the solids (solid electrolytes or mixed conductors) causes the ions to be inserted, extracted, transferred, or absorbed or transforms the states of the ions by redox reactions in the bulk or on the surface of the solid or on the interface of a (laminar or planar) solid ionic heterosystem. Several functions can be accomplished: (1) the optical response function of the soli…

From This Side of Pyrenees: An Overview of Autoethnography in Spain

2022

In recent years, we have witnessed a growing interest in autoethnography in Spain. However, the visibility of Spanish autoethnography within and beyond our borders continues to be limited. In this article, I have examined autoethnographic texts written by Spanish authors for the first time. I based this examination on a traditional bibliographic review of texts published in Spanish and English up to 2020. I organized texts according to my proposal for three stages of the development of Spanish autoethnography: its emergence, its dissemination from anthropology to other academic fields, and its consolidation and diversification. In these, I address the description of the content, the discipl…
