CdTe, CIGS, these are the main absorption layer for thin film solar cell. I am in search of potential replacement for these layer. Can anyone put me through some ideas or some study materials?
Thanks in advance
Dear Ifat,
You can use amorphous silicon with its pin structure. You can use also donor acceptor bulk heterojunction organic material where the organic polymer donor material acts as an effective absorber with about 200 to 400 nanometer thick layers sufficient for the absorption of the incident solar radiation. Also one can use perovskite organo metallic halide as very effective absorber.
For more information about the organic active materials please follow the link:file:///C:/Users/mac/Downloads/9781447148227-c2%20(2).pdf
For perovskite solar cells please see the link:https://www.ossila.com/pages/perovskites-and-perovskite-solar-cells-an-introduction

Dear Dr. Zekry,
Thanks for your kind suggestions, sir. But unfortunately I can not access to the file link you gave here sir. And I am more looking for inorganic compounds materials rather than organic ones. If you could enlighten me on those materials, that would be great.
Thank you sir.
Researchers are also working on CZTS (Copper-Zinc-Tin Sulfide) compound as absorber layer with ZnO and InS as window and buffer layers respectively. Search net for details.
Dear Ifat,
welcome,
I think this review paper will be very helpful to you:http://onlinelibrary.wiley.com/doi/10.1002/pip.541/pdf
Best wishes
For perovskites, have a look at these more recent review papers:

Thank you Sir @ Abdelhalim Zekry
Thank you Sir @ Jan-Martin Wagner
I will try to follow those articles. PLease keep us updated if there is anything new coming up. Thanks again.
I think the future is for Perovskite solar cells. There are so many fabrication methods in the laboratory scale. Solution processable hence price per watt will be competitive with other energy sources. Researchers work on to improve the stability which is the main concern. In the near future you will see them in the market. Let me know if you need papers related to fabrication of perovskite thin films.
Double Perovskite is important material but the problem with Perovskite material is its growth factor.
Dear Ifat,
the most studied alternatives to CIGS and CdTe are Cu2ZnSnS4 (CZTS)
and Cu2ZnSnSe4 (CZTSe), where non toxic, earth abundant and less
expensive elements are used in place of In, Ga, Cd and Te. CZTS and CZTSe, whose most stable crystalline form is kesterite, have a direct band gap of 1.4-1.5 eV and 1.0 eV, respectively, as well as an absorption coefficient higher than 10^4 cm-1, which make them suitable for PV applications. They share similar structure with the chalcopyrite CuInS2 except that half of the In is replaced with Zn and another half with Sn. Further alternatives are copper manganese tin sulfide
(CMTS) and copper iron tin sulfide (CFTS), which are still at an early optimization stage. However, since both Mn and Fe are definitely cheaper than Zn, optimized
CMTS and CFTS could potentially provide Wp cost definitely lower than CZTS and CZTSe, which is crucial for thin film PV applications.
In the last years, my research group worked on CZTS, CZTSe and CMTS so in my profile several papers you are maybe interest in are available as full text.
Best regards,
Alessia
