Band energy diagram of Heterojunction thin film solar cells

Al diseñar una celda solar es importante realizar él calculo del campo eléctrico interno (Zona de agotamiento, y potencial eléctrico interno (Vbi)) de la interface principal. Esta zona esta ubicada donde se juntan los dos semiconductores que forman la heterounión np. Como ejemplo particular formaremos la heterounión de una celda solar entre sulfuro de antimonio plata (AgSbS2, tipo-p) y sulfuro de cadmio (CdS, tipo-n). Acompañame a revisar cuales son las ecuaciones que describen el Vbi tanto para una celda solar de heterounión como para una de homounión. https://www.youtube.com/watch?v=fAKLOmhhn6I Webinar en grupo de trabajo CIDS-BUAP durante estancia posdoctoral-conacyt, Asesor.

Today I want to share my new curriculum vitae (CV) for pursuing an academic position in Mexico. If you are a new subscriber of my blog, you should know I am doing a second postdoctoral project at ICUAP-BUAP. The postdoc is a project to get professional experience for a scientific career. However, the small letters of a postdoc life say, "You have no permanent position yet," then you should constantly look for a job. That's why I am here to share my LaTex template with you. The original modern LaTex CV The open software culture encourages you to share your…

In the new Postdoctoral project, we are developing thin-film solar cell prototypes. However, some days ago I realize we will require the values of the solar irradiance W/m2 to determine the conversión efficiency $\eta =$ (VocJscFF)/(1000 W/m2) of our cell prototypes. The problem here is we will require an AM1.5 Solar simulator or a pyranometer to calibrate the irradiance (W/m2) of a light source. The possible solutions In my opinion, there are two ways to have these solar irradiance values: a) Fabricate a low-cost pyranometer using silicon photodiodes; b) Calibrate a reference solar cell (Si, crystalline or monocrystalline) using a…
