 OSLO, (PRLM-Aya/das).- Masalah terbesar dengan panel surya adalah harganya yang masih mahal. Sel surya memang merupakan energi terbarukan yang terbilang paling mahal. Tapi seorang profesor dari Swiss baru saja menerima anugerah Millennium Technology Prize untuk pengembangan sel surya murah yang bisa dipasang sebagai kaca jendela. Jadi, bukan lagi memasang panel surya di atap rumah, tetapi yang diperlukan hanya memasangnya sebagai jendela. Gratzel mengatakan teknologi itu terinspirasi oleh fotosintesis, proses di mana tumbuhan memperoleh energi dari matahari.

Michael Gratzel menghabiskan dua dekade mengembangkan jenis sel surya revolusioner peka warna yang disebut sel Gratzel. Kelompok yang memberi penghargaan, Akademi Teknologi Finlandia, mengatakan penemuan ini merupakan lompatan besar untuk teknologi surya. "Harga/rasio kinerja sel surya Gratzel begitu sempurna, alternatif yang menjanjikan untuk fotovoltaik silikon standar," ujar juru bicaranya, seperti dikutip Discovery News, baru-baru ini.
