후면전극 태양전지에서 n-type Si가 주로 쓰이는 이유

안녕하세요? 후면전극 태양전지 관해 공부하고 있습니다. 그런데 n-type Si가 많이 쓰이더라구요.. FZ, CZ 할것 없이요. 후면전극 태양전지의 경우 왜 p-type이 아닌 n-type이 쓰이는지 궁금합니다. 1. carrier lifetime이 길어서 그런가요? 2. 가격은 비싼가요? 3. 만약 가격이 비싸다면 왜 비싼가요? 등에 대해 알고 싶습니다. 어쨋든 왜 쓰이는지를 알고 싶습니다. 감사합니다.

    n-type silicon has been proven to have a higher tolerance to common transition metal impurities, such as those present in silicon produced from quartz and carbon (via metallurgical routes), potentially resulting in higher minority carrier diffusion lengths compared to p-type substrates. In spite of these advantages, at present, more than 85% of the silicon solar cells produced by the industry are based on p-type substrates. This is caused mostly by an insufficient development and industry implementation of the n-type cell processes for multicrystalline substrates. 아래 논문(open source) 검색하면 됩니다.
