What I should do with the used battery? The answer is to trash it, but correctly. Here, I will show you how to do it and what more we can learn from this technology. Li-ion battery is a highly…
Looking for PV-Lab (Photovoltaic Labs ) on the web I found this video which explains the process of the development of silicon (Si) solar cells. It seems interesting so I want to share it with you. The most efficient silicon solar cells in 2020 are developed using Si-heterojunctions (26.7% lab and 24.4% module) [1]. The junction is formed between the crystalline silicon (Eg = 1.12 eV ) and amorphous silicon (Eg = 1.75 eV) deposited on each face of the…
The DIY or Do It Yourself culture is a great way to fight against the programmed or built-in obsolesce. I have owned this phone for 4 years; since then I have kept it with me almost everywhere. This Technology has helped me to reduce wasted time in routine tasks like doing lines in the bank.
