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...

The Sunweb Solar Cell offers 2% higher output

Solland Solar, a solar cell manufacturer based in The Netherlands has developed a unique looking photovoltaic cell called the Sunweb. Not only does the new technology look cool but the Sunweb solar cell concentrates the generated electricity to the back of the cell, resulting in a 2% higher output per cell. The Sunweb solar cell was developed in conjunction with the Energy Research Center of The Netherlands. Typically, with traditional solar cells, a bus bar on the front of each solar cell result in a smaller surface area to collect sunlight. Although with the SunWeb the bus bars are located on the back of the cell allowing more surface area to generate electricity. Commercial production of the SunWeb solar cell will begin in 2009. We’re seeing more developments down to the cell level in increasing efficiency of a solar power system, every time the industry makes developments to increase the efficiency solar becomes a more attractive solution for the mainstream public. Even though the Sunweb only increases output by 2%, every small gain is a step in the right direction. What do you...

Sanyo Solar Electric creating green jobs in America.

Sanyo Electric is planning to expand it’s manufacturing capacity by investing in a solar wafers facility in Salem, Oregon. From Oregon the solar wafers will be shipped to Japan to be made into solar cells and finally will be shipped to factories within Japan or Mexico and Hungry for the final step of turning solar cells into sanyo high efficency solar panels. Sanyo expects to invest 80 million dollars into the solar wafer factory which will create 200 “green jobs” here right in America! Sanyo has been expanding its solar power business to keep up with the demand in the market for solar panels. The company is also considering to expand it’s operations in Mexico and Hungry. Solar Wafers are silicon sheets that are cut into solar cells, According to a statement by Sanyo, Full capacity of 70 megawatts (MW) worth of wafers per year will be reached by April...

Solar Arrays, Explained.

I read a lot of articles out there related to solar energy and I’ve seen many different terms used by authors describing a Photovoltaic Module. Photovoltaic Module, What does it mean? Its just a solar industry term that describes a solar panel that can covert light into electricity. But people often refer to panels as “solar arrays” or “solar cells” and I noticed many people get confused by the different terminology. So lets break it down, The Introduction to Photovoltaic Systems by the infinite power organization of Texas has a great diagram. A group of individual cells make up a solar panel (module) and a group of solar panels create an Array. Typically, people install a solar arrays on their roofs or ground mount solar arrays, rarely solar arrays are mounted to tracking systems to follow the path of the sun. The number of solar panels that make up an array depend on individual project goal, budget and needs. The great aspect of a solar array is that the panels are modular, meaning you can add more panels to the array at a later date to generate more electricity. There are a growing amount of people who are concentrating sunlight onto each solar cell that by magnifying the intensity of the sun and generating a greater output per solar panel, imagine taking a large magnifying glass and putting it over a solar array. Over clocking a solar panel, just like people over clock computer processors for more processing...

PowerFlex Solar Strings by Global Solar Energy

Thin Film solar panels are becoming more popular as the cost continues to be driven down through using elements besides silicon to produce solar cells. The PowerFlex Solar Strings manufactured by Global Solar Energy, come pre-connected to the Copper Indium Gallium diSelenide (CIGS) which are flexible that make it easy and affordable for product designers who are looking to retrofit products with solar. The company is able to offer these solar cells to the market through a “roll-to-roll” manufacturing process which makes the solar cells flexible and affordable in nature. The PowerFlex Solar Strings are the only “drop-in” solar cells available and really help people who are looking specifically to create products with solar power embedded in the products. These cells can be integrated into Building Integrated Photovoltaic products such as roofing shingles, facades of buildings, windows or we could soon see our laptops and other electronics offerings these types of solar power cells implemented within the products. Global Solar Energy has a great reputation in manufacturing consumer portable solar thin film charging...
