A Wondrous Invention

Energy needs are increasing daily. Conventional solar panels require vast

areas of land Transparent solar panels can be placed

in a number of places Thus, more electricity but less land

wasted.

Working principle

Appearance of normal transparent glass. The glass layer is towards the right. Photovoltaic coating is towards the left. Transparent luminescent solar

concentrator(TLSC) layer is used This layer helps to luminesce NIR and

and UV light Thin strips of PV cells near the edge of

the glass produce electricity.

Spectral response

The spectral response shows the wavelength of the photon that are accepted

Conventional PV cells absorb all light.

Transparent solar cells allow visible light to pass through absorbing

Multiple peaks as all spectra of light are not absorbed.

Merits and demerits

Merits Aesthetically pleasing

when used as glass windows

Glass can still be colored as murals or paintings will be behind the PV layer

Profitable as it can be laid on already built structures

No extra land needed Reduced electricity

consumption from power plants

Cells phone integration will lead to self charging phones

Demerits Still no widespread

use as further research is going on for commercial and household use

Current prototypes are costly. But price is expected to drop corresponding to breakthroughs.

Future Prospects

Research into this technology is still ongoing

Engineers and scientists are trying to optimize the performance of this device by using different semiconductors and devices to increase efficiency

Expected to be highly profitable It is expected that the first commercial

products will be used in mobile electronic devices.

OVERVIEW

Researchers are making transparent solar cells that could turn everyday products such as windows and electronic devices into power generators—without altering how they look or function today. Their new solar cells absorb only infrared and ultraviolet light. Visible light passes through the cells , so our eyes don’t know they’re there. Using simple room-temperature methods, the researchers have deposited coatings of their solar cells on various materials and have used them to run electronic displays using ambient light. They estimate that using coated windows in a skyscraper could provide more than a quarter of the building’s energy needs without changing its look. They’re now beginning to integrate their solar cells into consumer products, including mobile device displays.
