Abstract
Yoğunlaştırmalı Fotovoltaik (CPV) sistemler, konvansiyonel kristal
silisyum ve ince film fotovoltaik (PV) enerji dönüşüm sistemlerine önemli bir
alternatif olarak görülmektedir. Bu sistemlerde, lensler veya aynalar geniş bir
alandan güneş ışığını toplayarak, küçük alanlı yüksek verimli fotovoltaik güneş
hücresinin üzerine odaklamaktadır. Orta yoğunlaştırma seviyesine sahip ve yatay
ışık kılavuzuna dayanan yeni bir yoğunlaştırılmış güneş paneli
gerçekleştirilmiştir. Optik bileşenler, PMMA malzemesi kullanılarak düşük
maliyetli bir yöntem kullanılarak üretilmiştir. Lazer oluklu gömülü temaslı
silisyum güneş pilleri, optik ve elektrik kayıplarını en aza indirmek için bu
uygulama için özel olarak üretilmiştir. 15 cm x 15 cm'lik alana sahip tam bir
mini modül monte edilerek test edilmiştir. Test sonuçları beklentilerle uyum içindedir
ve sistemi daha da geliştirmek için kayıplara neden olan temel problemler
tanımlanmıştır. Silisyum güneş pili teknolojisi ve seri üretime uygun düşük
maliyetli imalat yöntemleriyle, %80'den daha yüksek bir optik verimliliğin ve
170 W/m2'yi aşan panel gücünün elde edilebilmesinin mümkün olduğu
gösterilmiştir.

Abstract
Concentrated photovoltaic (CPV) systems have proven to be an important
alternative to conventional crystalline silicon and thin film photovoltaic (PV)
energy conversion systems. In CPV systems, lenses or mirrors are used to
collect sunlight from a large area and to focus it onto a small area of a high
efficiency photovoltaic cell. In this paper, we report the realization of a new
CPV concentrator that is based on a horizontally staggered light guide system
with a medium concentration level. The optical components were manufactured using
a low-cost method, with PMMA as the optical material. Laser-grooved
buried-contact silicon solar cells were used and these cells are specially
designed and fabricated for this application to minimize the optical and
electrical losses. A complete mini-module with a 15 cm x 15 cm area was
assembled and tested under outdoor conditions. The test results are in good
agreement with the expectations and the main problems causing losses are
identified to further improve the system. It is shown that an optical efficiency
of higher than 80%, leading to a module power that exceeds 170 W/m2,
is attainable with existing Si solar cell technology with cost effective
manufacturing methods.
