A solar module comprises six components, but arguably the most important one is the photovoltaic cell, which generates electricity.The conversion of sunlight, made up of particles called photons, into electrical energy by a solar cell is called the "photovoltaic effect" - hence why we refer to solar cells as "photovoltaic", or PV for short.
As such, nanocells can work as nano-modulators for photoelectric enhancement rather than traditional photovoltaic cells for energy conversion. Fig. 1: Photovoltaic nanocell.
Dye-sensitized solar cells (DSSCs) belong to the group of thin-film solar cells which have been under extensive research for more than two decades due to their low cost, simple preparation methodology, low toxicity and ease of production. Still, there is lot of scope for the replacement of current DSSC materials due to their high cost, less abundance, and long-term stability. The …
