Sel surya
Sel surya atau sel photovoltaic, adalah sebuah alat semikonduktor yang terdiri dari sebuah wilayah-besar diode p-n junction, di mana, dalam hadirnya cahaya matahari mampu menciptakan energi listrik yang berguna. Pengubahan ini disebut efek photovoltaic. Bidang riset berhubungan dengan sel surya dikenal sebagai photovoltaics.
Sel surya memiliki banyak aplikasi. Mereka terutama cocok untuk digunakan bila tenaga listrik dari grid tidak tersedia, seperti di wilayah terpencil, satelit pengorbit bumi, kalkulator genggam, pompa air, dll. Sel surya (dalam bentuk modul atau panel surya) dapat dipasang di atap gedung di mana mereka berhubungan dengan inverter ke grid listrik dalam sebuah pengaturan net metering.
Banyak bahan semikonduktor yang dapat dipakai untuk membuat sel surya diantaranya Silikon, Titanium Oksida, Germanium, dll.
