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…

T. S. Nair Link: ECS Journal of Solid State Science and Technology, 8 (6) Q89-Q95 (2019) Abstract   We present thin film antimony sulfide selenide prototype photovoltaic modules of area, seven cm2 and conversion efficiency (η) of 3.5%. The thin films of Sb2SxSe3-x (x, 0.8–1.6) of 120–180 nm in thickness were deposited on FTO/CdS(80 nm) substrates at 80°C from chemical bath containing potassium antimony tartrate, thioacetamide and sodium selenosulfate. Thin film of…

Cited 1900 times (May 2019) -  Journal: Advanced Energy Materials Link: Device Characteristics of CZTSSe Thin-Film Solar Cells with 12.6% Efficiency Challenge: Decrease Voc deficit of current CZTSSe (1.13 eV) solar cells. The reported device has 12.6 % efficiency with  500 mV of Voc from a maximum of 820 mV calculated by SQ analysis. Therefore if Voc is enhanced the device would get better. But to achieve this enhancement we should understand the dependence between minority carrier lifetime and recombination process. Highlights: Kesterites are fabricated with Cu-poor and Zn-rich content Understand:  junction CdS/CZTSSe, current collection and recombination mechanism Defects impact the…
