Description
まず、250μmの厚みにスライスされた縦12.5cm×横12.5cmの正方形のn型の単結晶シリコン基板について、スライスダメージを除去するため、NaOH溶液により、シリコン基板を厚み200μmまでエッチングした。なお、NaOH溶液の代わりに、フッ酸溶液と硝酸溶液とからなるフッ硝酸でエッチングしても同様にスライスダメージを除去できる。また、単結晶シリコン基板の代わりに、多結晶シリコン基板を用いることもできる。さらに、p型シリコン基板を用いても同様である。
p型領域およびn型領域を散点状に配置したが、p型領域の合計面積とn型領域の合計面積とを等しくし、その後、p型領域上にp電極を形成し、n型領域上にn電極をそれぞれ形成した以外は、実施例1と同様にして太陽電池を製造した。得られた太陽電池は、短絡電流密度(Jsc)が33.80mA/cm2であって、開放電圧(Voc)が0.642Vであった。
ライン状のp型領域およびn型領域を図3に示すように配置し、また、p電極およびn電極を図4に示すように配置した以外は、実施例1と同様にして太陽電池を製造した。得られた太陽電池は、p型領域の合計面積が、n型領域の合計面積とほぼ同一であり、短絡電流密度(Jsc)は37.00mA/cm2であって、開放電圧(Voc)は0.635Vであった。
