According to “High-Efficiency, Mass-Producible, and Colored Solar Photovoltaics Enabled by Self-Assembled Photonic Glass” from ACS Nano, solar panels aren’t just for rooftops anymore – some buildings even have these power-generating structures all over their facades. But as more buildings and public spaces incorporate photovoltaic technologies, their monotonous black color could leave onlookers underwhelmed. Now, researchers reporting in ACS Nano have created solar panels that take on colorfu...
