光(guang)電二極(ji)管(guan)(guan)的(de)(de)關(guan)鍵(jian)要(yao)求之(zhi)一是(shi)收集(ji)(ji)光(guang)的(de)(de)合適區域。在(zai)標(biao)準(zhun)PN結內，這(zhe)相對較小，但可(ke)(ke)(ke)以(yi)(yi)(yi)(yi)通過(guo)使用(yong)PIN二極(ji)管(guan)(guan)來增(zeng)加面(mian)(mian)(mian)積。由于(yu)本(ben)(ben)征區域包(bao)(bao)含在(zai)用(yong)于(yu)集(ji)(ji)光(guang)的(de)(de)有(you)源(yuan)結中(zhong)，因此用(yong)于(yu)集(ji)(ji)光(guang)的(de)(de)區域要(yao)大得多，從(cong)而(er)使PIN光(guang)電二極(ji)管(guan)(guan)更有(you)效。在(zai)光(guang)電二極(ji)管(guan)(guan)制造過(guo)程中(zhong)，在(zai)P型和(he)N型層(ceng)(ceng)之(zhi)間插入了厚的(de)(de)本(ben)(ben)征層(ceng)(ceng)。該中(zhong)間本(ben)(ben)征層(ceng)(ceng)可(ke)(ke)(ke)以(yi)(yi)(yi)(yi)是(shi)完全本(ben)(ben)征的(de)(de)，或者是(shi)非常輕摻(chan)雜的(de)(de)以(yi)(yi)(yi)(yi)使其(qi)成(cheng)為N-層(ceng)(ceng)。在(zai)某些情況下，它可(ke)(ke)(ke)以(yi)(yi)(yi)(yi)作(zuo)為外延(yan)層(ceng)(ceng)生長到(dao)襯(chen)底(di)上(shang)(shang)，或者它可(ke)(ke)(ke)以(yi)(yi)(yi)(yi)包(bao)(bao)含在(zai)襯(chen)底(di)本(ben)(ben)身內。P+擴散層(ceng)(ceng)的(de)(de)開(kai)發可(ke)(ke)(ke)以(yi)(yi)(yi)(yi)在(zai)重摻(chan)雜的(de)(de)N型外延(yan)層(ceng)(ceng)上(shang)(shang)進行(xing)。觸(chu)點(dian)采(cai)用(yong)金(jin)屬設計，可(ke)(ke)(ke)制成(cheng)陽(yang)極(ji)和(he)陰極(ji)等兩(liang)個端子。二極(ji)管(guan)(guan)的(de)(de)前部區域可(ke)(ke)(ke)以(yi)(yi)(yi)(yi)分(fen)為兩(liang)種(zhong)(zhong)類型，例如(ru)有(you)源(yuan)表(biao)(biao)面(mian)(mian)(mian)和(he)無源(yuan)表(biao)(biao)面(mian)(mian)(mian)。非活性(xing)表(biao)(biao)面(mian)(mian)(mian)的(de)(de)設計可(ke)(ke)(ke)以(yi)(yi)(yi)(yi)用(yong)二氧化硅(gui)(SiO2)完成(cheng)。在(zai)活動(dong)表(biao)(biao)面(mian)(mian)(mian)上(shang)(shang)，光(guang)線(xian)可(ke)(ke)(ke)以(yi)(yi)(yi)(yi)照射在(zai)其(qi)上(shang)(shang)，而(er)在(zai)非活動(dong)表(biao)(biao)面(mian)(mian)(mian)上(shang)(shang)，光(guang)線(xian)不能照射。通過(guo)抗反(fan)射材料覆蓋活性(xing)表(biao)(biao)面(mian)(mian)(mian)，使光(guang)的(de)(de)能量不會損失，比(bi)較高可(ke)(ke)(ke)以(yi)(yi)(yi)(yi)轉化為電流。+太陽(yang)能電池(chi)是(shi)一種(zhong)(zhong)半導(dao)體(ti)器(qi)件。當陽(yang)光(guang)照射到(dao)半導(dao)體(ti)上(shang)(shang)時(shi)，一部分(fen)被(bei)反(fan)射，其(qi)余(yu)部分(fen)被(bei)吸收或穿透半導(dao)體(ti)。
