A new conversion process promises zero carbon emissions during production—but some question whether it will scale.
Scientists at Lawrence Berkeley National Laboratory announced Wednesday that they have been able to confirm a new high-efficiency solar cell design that utilizes nearly the entire solar spectrum.
Translation: They figured out a way to make solar panels generate electricity in the dark.
In earlier trials, the researchers used different alloys that achieved full spectrum responses but involved very high production costs. The advantage of gallium arsenide nitride is that it is very similar to a conventional semiconductor, gallium arsenide, and it can be produced with a commonly used fabrication method involving chemical vapor deposition.
The Lawrence Berkeley breakthrough represents just one path to increasing the efficiency and lowering the cost of solar cells. Over at Ohio State University, a full spectrum solar cell is also under development, and Stanford is pursuing a new technology that cuts around the problem of solar cell efficiency loss due to high temperature
In the meantime, you could just turn any metal surface into solar panels with photovoltaic spray paint.

“A MIT researcher has demonstrated a reaction which resembles the photosynthesis process that plants make each day which means that from now on solar power could be deployed at world scale. Using catalysts developed by the chemist, he showed a video where oxygen was generated from water, just like plants do it in photosynthesis.” …“Oxygen is pouring off of this electrode. This is the future. We’ve got the leaf.”

Because, it gives me the chance to build a dream.
Wikipedia:
Engineers work to develop economical and safe solutions to practical problems, by applying mathematics, scientific knowledge and ingenuity while considering technical constraints. The term is derived from the Latin root "ingenium," meaning "cleverness". The industrial revolution and continuing technological developments of the last few centuries have changed the connotation of the term slightly, resulting in the perception of engineers as applied scientists. The work of engineers is the link between perceived needs of society and commercial applications.
