New Solar Panels Generate Energy from Indirect Sunlight

Commonly used solar cells require direct sunlight in order to be able to produce electricity. If these solar cells do not get enough sunlight, their efficiency considerably drops. Recently engineers from GreenSun Energy, a company based in Tel Aviv, presented their latest invention - a solar cell able to produce power from diffused light. The new solar cell features a specialized colored panel, resembling a colored plexi-glass.
According to GreenSun Energy, their latest invention has its glass made with fluorescent dyes and nanoparticle metals. Besides being more efficient, the new solar cells could also have a lower cost compared to traditional solar cells. Another advantage of the new solar cells is that they require 80 percent less silicon than the traditional ones (less silicon means a lower cost of production). When sunlight (be it direct or indirect) touches the panels, it disperses across and the metal nanoparticles bring the sunlight to the edges where the silicon is placed.

The company's latest invention costs $2.10/W and is 12 percent more efficient than the traditional solar cell, which costs around $4.54/W. In addition, the conventional solar cells have efficiency loss because of the heat that doesn't turn into energy, informs CleanTechnica. In the new solar panels, the sunlight is diffused across the entire panel, thus nanoparticles are able to bring light to the edges of the panel where the light is transformed into energy.

Currently the Tel Aviv-based company is working on making its latest invention even more efficient.

Engineers at GreenSun look forward towards increasing the efficiency of their new solar cell from 12 percent to 20 percent. They also hope to reduce the costs of producing the new panels to $0,94/W. link....
