Disclosed are a power-generating building material and a preparation process thereof. The power-generating building material applies the artistic appreciation and protection performance of an optical adjustment layer to the field of solar cells, so that the architectural art and power-generating performance are integrated to meet the requirements for green buildings and environmentally friendly buildings. The outer surface formed by a surface layer after curing is beautiful in texture. The power-generating building material has the texture and quality of a building material, is rich and diverse in expression form, without changing the architectural style and urban landscape, and has a broad application prospect.

Various embodiments herein relate to systems for powering electrochromic windows in a building. Systems may include photovoltaic panels configured to generate electrical power, energy storage device(s) configured for storing generated power, and one or more controllers on a network of electrochromic windows that are configured to receive power from the energy storage device(s) and power tint transitions in one or more electrochromic windows. Systems may include various additional circuit components described herein for regulating and/or controlling the generation, storage, and application of electric power. The systems and techniques described herein can be used to design networks of electrochromic windows that are hybrid-solar or off-the-grid (“OTG”).
