Silver Antimony Sulfide Selenide for Solar Cells

The International Material Research Congress (2021-IMRC) is coming next August 15-20th. In this event, I’ll be attending the Symposium C7 – Photovoltaics, Solar Energy Materials, and Technologies to present my research about the development of silver antimony sulfide selenide AgSbS₂, AgSbSe₂, AgSb(S,Se)₂ for solar cells [zotpressInText item=”{6612042:JUKWBKTL},{6612042:YYSGZIWM}”].

I have a story with the IMRC-Congress. When I was doing my Ph.D. project, My Advisor preferred to attendant the MRS-Fall and MRS-Spring meeting in the USA because IMRC at the Caribbean of Mexico seems like a vacation! I don’t know your experience, but In mine, a research meeting let me travel abroad for the first time, and that experience opened my mind to the world!

Now with the COVID-19 situation, I will attend but in virtual mode (What a shame). I know is for our safe then I have nothing to argue. Health, Family, and Science are first!

The Abstract – Silver Antimony Sulfide Selenide

Symposium: C7 Photovoltaics, Solar Energy Materials and Technologies
Congress participation: Virtual

The silver antimony sulfide-selenide – cubic- $AgSb(S,Se)_2$ is a potential p-type semiconductor for application in thin-film solar cells. In this work, we present perspectives of $AgSb(S,Se)_2$ to develop high-efficiency solar cells using this cubic metal chalcogenide semiconductor.
Material characterization of the $AgSbS_{1.3}Se_{0.7}$ solid solution confirms p-type conductivity with a bandgap of 1.48 eV and photoconductivity $(\sigma$ ) of $10^{-5}$ $\Omega^{-1} \text{cm}^{-1}$ .
The merit of incorporating silver atoms into the novel antimony chalcogenides ( $Sb_2S_3$ , $Sb_2Se_3$ ) comes from the transformation of orthorhombic structure into an FCC lattice, similar to that in rock salt structure.
The absorption coefficient of $\alpha > 10^5 \text{cm}^{-1}$ in the visible region of solar radiation in $AgSbS_{1.3}Se_{0.7}$ allows a maximum photo-generated current density of 29 ${\text{mA}}/{\text{cm}^2}$ for a 1 $\mu\text{m}$ thick film under standard air-mass 1.5 global (1000 W/m2) solar radiation.
The thin film solar cells of CdS/ $AgSbS_{1.3}Se_{0.7}$ heterojunction presents a fill factor of 0.64, open-circuit voltage of 537 mV, but a low short circuit current density of 2 mA/ $\text{cm}^2$ .
At this stage, chemical deposition has served for prototyping the solar cells. Improvements are expected using industrial chalcogenide growth techniques, which would enhance their carrier collection.

Are you planning a poster or an oral session?

Maybe you are planning to assist to a congress in the next moths. Is it your first time? What do you expect from these science events? If my experience in this kind of events can help you. I can write a new post attending your request. Would you please comment below?
