Many different companies use many different materials to manufacture many different types of photovoltaic cells and modules — like solar panels. But ultimately, all photovoltaic cells perform the same function. A photovoltaic cell harvests photons from sunlight and uses the photovoltaic effect to convert solar power into direct current electricity.
But ultimately, all photovoltaic cells perform the same function. A photovoltaic cell harvests photons from sunlight and uses the photovoltaic effect to convert solar power into direct current electricity. The photovoltaic cells contained in a PV module transmit DC electricity to an on-grid, off-grid, or hybrid solar system.
Silicon is the workhorse of modern electronic devices, but it performs poorly as a platform for photodetection in the infrared. Valerio Adinolfi and Edward Sargent offer a solution to this shortcoming in the form of a new device architecture, something they call the 'photovoltage field-effect transistor'.
The vast majority of photovoltaic cells used in modules like solar panels in residential PV systems are made from crystalline silicon nonmechanical semiconductive material. Regardless of what they’re made from (or for), semiconductors function by conducting electricity under specific conditions.
The different photovoltaic cells developed up to date can be classified into four main categories called generations (GEN), and the current market is mainly covered by the first two GEN. The 1GEN (mono or polycrystalline silicon cells and gallium arsenide) comprises well-known medium/low cost technologies that lead to moderate yields.
A self-powered transistor utilizing a renewable source of energy would therefore be a potential game-changing technology. Now a solar-powered field-effect transistor or “solaristor” has been demonstrated by the research groups of Mónica Lira-Cantú and Gustau Catalán at the Catalan Institute of Nanoscience and Nanotechnology (ICN2), Spain.
