Plastic photovoltaic cell

Dette er ei solcelle. Den er laget av plast, ikke silisium. Fagfolk i en rekke land utvikler og tester nå ut slike løsninger, i håp om å gjøre solenergi billigere. Dette eksemplaret er fotografert ved det franske solenergi-instituttet INES. Foto: NTB Scanpix / SPL

Plastic photovoltaic cell being held in a researcher’s hand. Photovoltaic cells, the basic components of solar panels, contain materials that can absorb energy from sunlight and convert it into an electrical current. In this photovoltaic cell, a plastic replaces silicon, which is the usual material used. The initial performance of the plastic is lower than that of silicon photovoltaic cells, but this technology could be used where energy efficiency requirements are not high.
