本発明による色素増感型太陽電池を次のように製造した。二酸化チタン2gとポリエチレングリコール(分子量20,000)0.4g、トリトンX−100 0.1g、硝酸溶液1ml、エタノール2ml、アセチルアセトン0.2gと蒸留水7mlを攪拌機に入れて攪拌機を作動させる。攪拌方法は15分攪拌し、5分間休止する過程を1サイクルにして20サイクル間作動させた後、蛍光物質YAG(Ce)を添加して光電極ペースト固形粉を作り、この際、YAG(Ce)の量は光電極ペースト固形粉100重量%に対して10重量%が含有されるようにして再び10サイクルの攪拌過程を通じて蛍光物質が含まれた光電極ペーストを製造する。
光電極の製造時に添加される蛍光物質YAG(Ce)を除いては、実施例と同じく製造した試料を比較例1とし、光電極の製造時に二次熱処理してから紫外線(UV)照射した試料を比較例2として本発明の実施例と比較した。
表2は、蛍光物質YAG(Ce)含有量による変換効率を示し、本発明により製造された試料の蛍光物質添加重量比を比較して添加量による電気的特性を比較したものである。
