Abstract
現在主流であるp型単結晶裏面不動態(PERC)太陽電池に置き換わる技術として,n型単結晶Siウエハを用いた各種太陽電池の研究開発が進展している。一方で,結晶Si太陽電池の変換効率は商用サイズウエハにおいても理論限界効率に迫りつつある。さらなる変換効率向上には異なるバンドギャップの太陽電池を組み合わせた多接合化の技術開発が必要である。最近では,ペロブスカイト太陽電池と組み合わせたペロブスカイト/結晶Siタンデム太陽電池が注目されている。変換効率の向上に加え,信頼性の向上による生涯発電量最大化が太陽光発電のいっそうの普及拡大に必要不可欠である。太陽電池モジュールの発電性能の低下要因と信頼性向上のために必要なモジュール技術についても言及する。Keywords
