Perkembangan Sel Surya (1/2)

Pengembangan Sel Surya Silikon secaraIndividu (chip) :

  • (^) Mono-crystalline (Si)
    • (^) Dibuat dari silikon kristal tunggal yang didapat dari peleburan silikon dalam bentuk bujur. Sekarang Mono-crystalline dapat dibuat setebal 200 mikron, dengan nilai effisiensi sekitar 24%.
  • (^) Poly-crystalline/Multi-crystalline (Si)
    • Dibuat dari peleburan silikon dalam tungku keramik, kemudian pendinginan perlahan untuk mendapatkan bahan campuran silikon yang akan timbul diatas lapisan silikon. Sel ini kurang efektif dibanding dengan sel Polycrystalline ( efektivitas 18% ), tetapi biaya lebih murah.
  • (^) Gallium Arsenide (GaAs)
    • Sel Surya III-V semikonduktor yang sangat efisien sekitar 25%.

Faktor Pengoperasian Sel Surya

  • (^) Ambient air temperature
  • (^) Radiasi solar matahari ( insolation )
  • (^) Kecepatan angin bertiup
  • (^) Keadaan atmosfir bumi
  • (^) Orientasi panel atau array PV
  • (^) Posisi letak sel surya ( array ) terhadap matahari ( tilt angle )
