I mostly based my experiment on this website [1]. There's no documentation about it yet, bust basically I alloyed zinc and antimony in a crucible at 700°C and splat-cooled it (pour onto a steel surface and squish the cooling metal with a copper block). The resulting disk is quite brittle. I mounted it in a improvised clamp, between a copper and german silver electrode. No diode behaviour could be measured. I think my backyard metallurgy is not very precise though. Also, my current way of holding the sample might be all kinds of bad. So some more messing around is needed [1] https://solar.lowtechmagazine.com/2021/10/how-to-build-a-low-tech-solar-panel https://solar.lowtechmagazine.com/2021/10/how-to-build-a-low...
