Silicon Photovoltaic Solar Cells | 10 Innovations Around the world, billions of solar photovoltaic (PV) panels are powering homes, buildings, infrastructure and remote communities by converting sunlight directly into usable electricity. Solar is an important part of the renewable energy mix that will help move our global economy away from its reliance on fossil fuels, and the PV industry has benefited greatly from the pioneering work of UNSW researchers. In 1974, a young Australian named Martin Green began working at UNSW after completing his doctorate on the structure of innovative microelectronics. A year later, Green’s research team produced its first silicon solar cell. It was the first step on a four-decade-long journey that has cemented UNSW’s reputation as a world-leading solar photovoltaic research institution. When Green came to UNSW, photovoltaic technology was still in its relative infancy. In the 1960s, after rapid efficiency progress, the technology began to find applications providing power onboard spacecraft.
