60 Years of Solar Cells

 

Bell executives presented the first practical solar cell to the world at a press conference on April 25, 1954.

At the time of Bell’s announcement in 1954, all the solar cells in the world delivered less than one watt. Today, more than 120 gigawatts of generating capacity of photovoltaics have been installed worldwide. This year not only marks the 60th anniversary of the silicon solar cell but also the beginning of reaching the Holy Grail solar scientists have only previously dreamt of before “ entering the Era of Grid Parity, where solar panels begin to generate power at costs equal to or less than electricity produced by fossil fuels and nuclear energy.

What does this mean? Simple! Massive amounts of cleanly produced electricity will become a reality in our lifetime.

In fact, on April 26, 1954, The New York Times noted on page one, that the Bell solar cell “may mark the beginning of a new era, leading eventually to the realization of one of mankind’s most cherished dreams“ – the harnessing of the almost limitless energy of the sun for the uses of civilization.  U.S. News and World Report came out with a story as full of hope as the Times piece with the title: Fuel Unlimited,” exclaiming that the silicon solar cells “…may provide more power than all the world’s coal, oil and uranium.¦Engineers are dreaming of silicon powerhouses. The future is limitless.”

The International Forum “ExpoElectronica” held its annual ROUND TABLE ‘PHOTOVOLTAICS – A NEW VECTOR OF ELECTRONICS DEVELOPMENT’

April 12, 2013 in Moscow, Crocus Expo, the International Forum “Expo Electronica” held its annual Roundtable “Photovoltaics – a new vector of electronics development”

Scientists, businessmen, investors operating in a promising area, discussed the most pressing theoretical and practical issues:

Moderator of the round table was Andrew G. Kazanskii – Doctor of Science, Professor of Moscow State University.

Lux Research: Equipment upgrades key for PV manufacturers to compete

Lux Research finds that despite c-Si capacity utilization rates of 55% in 2012, new equipment investments will be necessary

On October 25th, 2012 Lux Research Inc. (Boston, Massachusetts, U.S.) released a new report which states that solar photovoltaic (PV) equipment manufacturers need to acquire innovative production equipment in order to cut costs, increase margins, and offer differentiated products.

“Turning lemons into lemonade: Opportunities in the turbulent photovoltaic equipment market” notes that in 2012, global capacity utilization has fallen to 55% for crystalline silicon (c-Si) module production and 70-80% for leading thin film module technologies. The report says that as a result of this cell and module manufacturers must differentiate their products to regain profitability.

“Across the industry there is recognition that innovation is needed to survive a shakeout,” said Lux Research Analyst Fatima Toor, lead author of the report. “Equipment suppliers have a vital role to play in enabling that innovation.”

Possibilities for cost reduction in c-Si manufacturing

Among the findings of the report is that there are gains to be made in reducing silicon costs, including reducing silicon waste by use of direct solidification and epitaxial silicon wafer growth techniques. Lux Research also finds that quasi-monocrystalline silicon ingot growth also enables a 40% cost reduction for c-Si wafers.

For copper indium gallium diselenide (CIGS) technology, Lux Research emphasizes standardization, noting that while CIGS producers currently rely on customized equipment, that off-the-shelf tools and improved throughput will drive higher efficiencies.

Finally, the report finds that new cell designs will drive equipment upgrades, specifically mentioning selective emitter and heterojunction with intrinsic layer (HIT) technologies.

For more information, please see Solar Server’s interview with Fatima Toor on the report and its findings.
