The photovoltaic and solar thermal units are mutually constrained in conventional Solar Photovoltaic/Thermal (PV/T) systems which usually mainly generates electricity collects heat as a supplement. In the situation for main-demand energy, PV/T overall efficiency is lower, so an innovation system based on energy supplemented power proposed. And reversible thermochromic materials from chemical field applied to collectors coating of decoupling with energy. thermoelectric performance PV panels, uncoated experimentally investigated. results show that adding appropriate amount high conductivity powder collector increase efficiency. obtains highest when mass fraction graphite 10,000 purpose 2‰ added coating. When temperature below 45 ℃, collecting fluid rapidly, above ℃ becomes colorless translucent passes through reaches cell increases. This can automatically adjust output ratio certain extent. occasion where main demand, primary rate improved.
