Sharp Solar Breaks Conversion Efficiency Record
Sharp Solar Breaks Conversion Efficiency Record
According to the company, it’s a title-holding 35.8 percent cell conversion efficiency with the help of a triple-junction compound cell. Sharp team has been working on this project since 2000.

Carbon-based Solar Cells
Graphene is a single sheet of carbon, one atom thick. Graphene has potential to be utilized as an effective, less toxic and cheaper than other alternatives for solar cells. Chemists at Indiana University Bloomington are trying to come up with a better alternative than silicon. If successful, this can be a path breaking discovery.

PV Cell Prototype Generates Electricity from IR and UV Light
PV Cell Prototype Generates Electricity from IR and UV Light
Recently scientists at the Kyoto Institute of Technology have deviated from the normal path and tried to trap the visible as well as invisible rays of sun for electricity. They tried to create a new photovoltaic cell that can capture visible, infrared and ultraviolet light of the sun. The team now thinks that this photovoltaic will be highly efficient for solar power conversion.
These new PV cells were made up of gallium nitride (GaN) semiconductor. This new photovoltaic cell is created by ‘doping’ a wide bandgap transparent composite semiconductor i.e. gallium nitride (GaN) with a 3d transition metal such as manganese. Gallium belongs to the family of scandium, titanium, vanadium, chrome, iron, cobalt, nickel, copper, and zinc. Sonoda explained that his team has gone for those additive elements. He said that even aluminum nitride (AlN), which has a very large bandgap, can possibly have an absorbing region in the visible light range,

Multi-layer gallium stacks
Sun Shines on Solar Energy Future
Instead of thin single-layer gallium arsenide deposited on small wafers, the Illinois group tried to create ‘pancake’-like stacks of 10 layers deposited at one go and peel the layers off individually, transfer them and lay them side by side. Giving all details of this procedure, Professor Rogers, the Lee J. Flory Founder Chair in Engineering Innovation & Professor of materials science and engineering and of chemistry said, “We’re creating bulk quantities of material, as opposed to just the thin single-layer manner in which it is typically grown…. “You really multiply the area coverage, and by a similar multiplier you reduce the cost, while at the same time eliminating the consumption of the wafer.”

Increasing Solar Conversion with Quantum Dots
Costs for Thermo-photovoltaic Cells Significantly Reduced
Thermo-photovoltaic (TPV) cells are great for converting radiation from any heat source to power. These cells can generate power from the wasted heat which gets released when glass or steel is produced. Adding these TPV cells to domestic power systems can help generate power along with heating water. TPV systems are also too complex for everyday use. Both of these reasons have made the TPV systems beyond industrial and domestic consumer routine set-up.

Economical Solar Panels to Yield More Energy
The thin silicon film layers in the amorphous solar panels are made of silane gas (SiH4). Van Elzakker found out that Staebler-Wronski effect can be alleviated by diluting the silane gas with hydrogen at an optimum ratio. In Van Elzakker’s words, “We showed that the influence of the Staebler-Wronski effect can be considerably reduced in this way.

Breakthrough in Thin-Film Solar Cells
Scientists at Johannes Gutenberg University Mainz (JGU) have come out with positive news about increased efficiency of thin-film solar cells. They opted for the computer simulations to probe deeper into the indium/gallium combination to increase the efficiency of Copper indium gallium (di)selenide (CIGS) thin-film solar cells. Till now CIGS has shown only about 20% efficiency though theoretically they can attain the efficiency levels of 30%.

PETE Process Promises Successful Technology Fusion
SLAC and Standford research initiative on increasing conversion efficiency of solar cells. In this new process, semiconducting material is coated with a thin layer of caesium which allows the material to use both the light and heat of sun to generate electricity. Though this is not actually standardized photovoltaic mechanism happening, this is a photovoltaic-like response happening best at very high temperatures. The new process is called Photon enhanced thermionic emission (PETE).
