I used glass as a transparent cover in the solar still. But the glass handling is quite difficult, it has good absorbance and medium reflective property. But I need an alternate material which has good absorptive and very low reflective property. Is there any please suggest ?
Quartz could be a good alternative to glass, it has better properties but is largely more expensive. Depending on what range of wavelength you want to use, specific glasses exist also like suprasil, infrasil ...
Good luck

Dear Karthick Munisamy
There are a number of clear plastics which could be used, and if you are seeking the lowest price possible for your system, these would be the way to go. They do however not have the same thermal properties as glass and so you will lose efficiency. I do not know what your constraints are in your system, but have you considered other solar desalination technologies apart from solar stills? The main problem with a solar still is that it is very inefficient (usually around 640 kWh/m3 of distillate) and as such would only be suitable for an emergency supply, since you would have to make a very big one to supply enough water for a family. Have you looked into humidification-dehumidification systems?
Good luck with your project.
Sincerely,
Jakob
