25% solar cell efficiency, a world’s record.

Last month, I wrote about Suniva a company that recently developed a 20% efficient solar cell. Today, Total Solar Energy, a frequent commentator on our blog pointed out that the New South Wales’ ARC Photovoltaic Centre of Excellence in Australia has the world’s record for most highly efficient solar cell at 25%. Recently, there has been changes in the international standards of how solar cells are measured in terms of a better understanding of atmospheric effects upon the colour content of sunlight. It’s now observed that the blue sunlight spectrum is absorbed strongly, very close to the cell surface on the flip side red sunlight spectrum is weakly absorbed. The cell developed by the ARC Photovoltaic Centre has a special design to trap the red sunlight spectrum more efficiently. First generation solar cells have a theoretical maximum of 29% efficiency according to scientist, solar cell technology is getting close to maxing out the first generation efficiencies. When do you think we will see 50% efficiencies? Solar cell technology is evolving so fast, does anyone know of a solar cell that has an efficiency of over...

Suniva’s 20% Efficent Solar Cell

Suniva, a newer entrant in the photovoltaic solar cell market claims its Research & Development team has created a solar cell that is capable of 20% efficiency using a simple cell design and screen printing technologies. The company backs up their claim by having their technology verified by the National Renewable Energy Laboratory (NREL). According to Suniva’s Founder & CTO, the company increase conversion efficiency while reducing processing time and achieving low costs. Suniva, manufacturers and markets its high efficiency solar cells under the ARTisun brand name which focuses on an intersection between high effiecncey and low cost. What does this mean to you? The purpose of this blog is to first understand how important solar cell technology is the overall adoption rate of solar photovoltaic technology, as the efficiencies increase and costs decrease, that means more affordable solar panels that break even quicker, this trend in technology will eventually be responsible for mass adoption of solar panels. Typically a group of solar cells make up a solar panel (module), check out my previous post titled, “Solar Arrays Explained” to understand how individual solars cells become a solar...
