Abstract
Description
(導電性ペーストの作製)
ガラス素材としてTeO2、Bi2O3、ZnO、Al2O3、ZrO2、SiO2、B2O3、BaO、MoO3、La2O3を用意し、表1に示すような配合量となるように、これらガラス素材を秤量して調製し、試料番号1〜14のガラスフリットを作製した。
縦50mm、横50mm、厚み0.2mmの単結晶のSi系半導体基板の表面全域に膜厚0.1μmの反射防止膜をプラズマ化学気相成長法(PECVD)で形成した。尚、このSi系半導体基板は、p型Si系半導体層の一部にPを拡散させ、これによりp型Si系半導体層の上面にn型Si系半導体層が形成されている。
試料番号1〜14の各試料について、ソーラーシミュレータ(英弘精機社製、SS−50XIL)を使用し、温度25℃、AM(エアマス)−1.5の条件下、電流−電圧特性曲線を測定し、この電流−電圧特性曲線から数式(1)で表わされる曲線因子FF(Fill Factor)を求めた。
ここで、Pmaxは試料の最大出力、Vocは出力端子を開放したときの開放電圧、Iscは出力端子を短絡したときの短絡電流である。
表2は試料番号1〜14の各試料のペースト組成、曲線因子FF、及び変換効率ηを示している。

3 受光面電極(電極)
