I have an open hardware project (libre, technically) to develop a solar powered phone. It's more of a concept, or a framework, rather than a list of components that I'm assembling outside of research. I would be more than happy if someone forked the idea and made something of it. https://hackaday.io/project/177716-the-libre-autarkic-laptop Anyone could manufacture it since the PCB, open cores (royalty free), blueprints and STL and PCB design would all be open sourced to anyone who wanted to make it, thus it encourages collaboration.
