Oerlikon Solar, a leading global supplier of field-proven turnkey solutions for thin-film silicon solar modules, introduced today its micromorph tandem technology highlighting its continued global strength in the growing solar industry. The environmentally friendly, energy-conscience micromorph tandem modules offer customers many advantages including the potential to achieve efficiencies of 10 percent and higher in the near future. Oerlikon Solar’s micromorph module technology, first invented by Dr. Johannes Meier, head of the company’s R&D activities, combines two different silicon materials – amorph and microcrystalline – in a top and a bottom cell. In this way, the amorphous top cell is converting the visible part of the suns spectrum while the microcrystalline bottom cell is absorbing the sun power in the near infrared spectrum. Consequently, the new micromorph tandem technology allows boosting the efficiency level by approximately 50 percent compared to traditional amorphous single cells. (more…)
