Enabling selective absorption in perovskite solar cells for refractometric sensing …
This transformation from a solar cell to a sensor also implies a discussion to properly describe the performance of the system as a dedicated refractometric sensors, or as a solar cell. In this contribution, we numerically analyze and propose a modified perovskite solar cell to work as a refractometric sensor for gases.
Individual solar cells can be connected together in series to form solar panels which increases the output voltage or connected together in parallel to increase the available current. Commercially available solar panels are rated in Watts, which is the product of the output voltage and current (Volts times Amps) when fully lit.
Confusion reigns over photocells and solar cells, but there is an easy way to tell them apart. A solar cell produces power for an electrical circuit while a photocell is a light-activated control switch. Photocells have been used since the mid 1900s in light meters while solar cells have only become popular since 1990.
