Solar panel light-transmitting plate

How does a solar cell work?

The semiconductor is doped to be a p-n junction with a potential difference, which will drive current flow vertically through the cell in one direction, so it can be harvested as electricity. The diffusion length is one of the important factors that affect the efficiency of the solar cell.

What is a transparent solar cell?

Transparency is a physical property that allows light to pass through without interrupting it. The core of this research is transparent solar cell (TSC) and its use in many applications that require optically transparent solar cells, such as car windows. What makes a material transparent is the arrangement of atoms and electrons in it.

Why do we need transparent photovoltaic (TPV) cells?

One of the main challenges that most of these applications face is the surface area needed to produce enough electricity in the solar panel; the larger the surface area is, the more sunlight a PV can harness. Hence, the idea of transparent photovoltaic (TPV) cells came to solve this challenge of effectively utilising space.

How do transparent luminescent solar cells work?

Transparent luminescent solar cells use a different structure, in which the solar cells are placed on a frame, and NIR fluorescent transparent dyes are pasted on the active area. This meant that fluorescent paste would absorb NIR light and direct it to the edge of the glass, where it is converted to electricity.

Can transparent solar cells power a building?

Building integrated photovoltaics, also known as BIPV, is the nearest application for transparent solar cells. If all the buildings with 90% glass on their surface used transparent solar cells printed on the surface of the glass, the solar cells have the potential to power more than 40% of that building's energy consumption.

Can transparent solar cells be used for photonic absorption?

Conclusion Transparent solar cells are very challenging devices to fabricate and have the potential to be used for a large number of applications. The challenge lies in the fact that transparency intrinsically conflicts with the concept of photonic absorption.
