Original MIT press release: http://newsoffice.mit.edu/2014/recycling-batteries-into-solar-cells-0818 http://newsoffice.mit.edu/2014/recycling-batteries-into-sola... Paper (non free, unfortunately): http://pubs.rsc.org/en/Content/ArticleLanding/2014/EE/C4EE00965G#!divAbstract http://pubs.rsc.org/en/Content/ArticleLanding/2014/EE/C4EE00... As far as I understand it (I am not a chemist), the video only shows the production of perovskite crystals. The paper goes into more details on the fabrictation process of actual solar cells: - Patterning the FTO coated glass (glass with a transparent, conductive layer; you can buy this commercially) using photolithography. - Depositing a 500nm thick layer of 20 nm TiO2 nanoparticles - Depositing the perovskite (this is what is shown in the video) - Depositing a 50nm gold layer
