You ’re looking at the Applied Bacini Pegaso — one of the most productive solar cell impression origin on the planet — fabricating electric circuits on both sides of a solar cell . And by productive , I mean 20 million cells a year , enough to power 10,000 typical US homes .
Two cassette — each holding 40 Photovoltaic wafer — are adulterate into the scheme every 100 bit . The Pegaso ’s wafer - handling mechanism moves wafers between two independent conveyor caterpillar track to optimise output — it can finish a solar cellphone every 1.2 second when go at maximal capacity — where they travel to the screen pressman .
There , duple print heads impel conductive silver gray paste through limited screens to create micrometer - level contact lens line on the wafer . These print heads can adjust printing parameters “ on - the - fly ” between wafer . Once they clear an initial undulation of inspection , the wafers are flash bake to dry and slightly harden the contact lines before being shuttled to a high temperature furnace that then evoke the metal into the Si .
After they ’ve cool down , they then undergo a 2nd rung of inspection and examination — first through an optical digital scanner to ensure the contact ancestry are accurate , then through an IV examiner to confirm the business leader output . The solar jail cell are then sort by their level of efficiency in the IV test and packaged for distribution . [ Applied Materials ]
