Introduction Literature review during a research project is essential to avoid duplicate work. I mean If something is already study we don't need to re-invent the wheel. In that case we should take advantage from the published paper to replicate the results and then push the knowledge forward with our new discoveries. This time I will read and take notes from the paper "High-Resistance Metal Oxide Window Layers for Optimal Front Contact Interfaces in Sb2Se3 Solar Cells" to learn about the insertion of Metal Oxides as High-Resistive Transport (HRT) layers in antimony selenide (Sb2Se3) solar cells (TCO/HRT/CdS/Sb2Se3/Au). It is already reported that…
