Besides wind and geothermal energy, photovoltaic power is considered to be one of the most promising sources of renewable energy. Photovoltaic devices work according to the capacities of specially-treated semiconductors, which convert solar energy into continuous-current electricity. Research in this field has made significant progress and is focused on increasing the energy efficiency of photovoltaic devices while reducing production and maintenance costs.
The UV curing process is employed for various aspects of solar panel production. This has resulted in production line improvements by reducing production cost, as mentioned, while maintaining the high quality and performance of the finished product. A notable example is the printing of circuits with UV-curable conductive inks. These inks can be printed onto the energy-absorbing sheet of the photovoltaic cell in a roll-to-roll format, creating a very efficient UV process.
