Umehluko omkhulu phakathi kohlobo lwe-N nohlobo lwe-P-monocrystalline wafers we-silicon we-solar photovoltaics
Ama-wafers e-silicon e-Monocrystalline anezakhiwo ezibonakalayo zama-quasi-metals, ane-conductivity ebuthakathaka, futhi ukuhamba kwawo kukhuphuka ngokunyuka kwezinga lokushisa. Futhi banezakhiwo ezibalulekile ze-semiconducting. Ngokusebenzisa i-doping ama-wafers e-silicon e-ultra-pure monocrystalline anamanani amancane e-boron, ukuqhutshwa kwe-conductivity kunganyuswa ukuze kwakhiwe uhlobo lwe-P-silicon semiconductor. Ngokufanayo, ukusebenzisa i-doping ngenani elincane le-phosphorus noma i-arsenic nakho kungakhuphula ukusebenza, kwakhiwe i-semiconductor ye-silicon yohlobo lwe-N. Ngakho-ke, yimuphi umehluko phakathi kwama-silicon wafers we-P nohlobo lwe-N?
Umehluko omkhulu phakathi kohlobo lwe-P nohlobo lwe-N-monocrystalline wafers we-silicon imi kanje:
I-Dopant: Ku-silicon ye-monocrystalline, ukudotshwa nge-phosphorus kuyenza ibe uhlobo lwe-N, kanti ukudotshwa nge-boron kuyenza ibe uhlobo lwe-P.
I-Conductivity: Uhlobo lwe-N luyi-electron-conducting, futhi uhlobo lwe-P luqhuba imbobo.
Ukusebenza: Lapho i-phosphorus eyengeziwe ifakwa ohlotsheni lwe-N, lapho kukhona ama-electron amahhala, i-conductivity inamandla, futhi i-resistivity iyancipha. Lapho i-boron ifakwa ohlotsheni lwe-P, izimbobo ezengeziwe zikhiqizwa ngokufaka i-silicon, i-conductivity inamandla, futhi i-resistivity iyancipha.
Njengamanje, ama-silicon wafers ohlobo lwe-P ayimikhiqizo ejwayelekile embonini ye-photovoltaic. Ama-silicon wafers alula ukuwenza futhi anezindleko eziphansi. Ama-silicon wafers ohlobo lwe-N ngokuvamile anesikhathi eside sokuphila esithwala abantu abambalwa, futhi ukusebenza kahle kwamaseli elanga kungenziwa kube phezulu, kodwa inqubo iba nzima kakhulu. Ama-silicon wafers ohlobo lwe-N afakwe i-phosphorus, engancibiliki kahle nge-silicon. Ngesikhathi sokudweba induku, i-phosphorus ayisakazwa ngokulinganayo. Ama-silicon wafers ohlobo lwe-P afakwe i-boron, ene-coefficient yokuhlukanisa efanayo ne-silicon, futhi ukufana kokuhlakazeka kulula ukulawula.
