Investigation of the parameters affecting the total efficiency of solar energy panels designed with half and full photovoltaic cells

Öz

Solar power (SP) has been one of the most promising renewable energy sources to alleviate global environmental concerns and meet growing energy demand. Solar energy is used in different ways. One of them is photovoltaic (PV) cells. Photovoltaic cells are semiconductor materials that convert solar energy directly into electrical energy. Conventional photovoltaic modules are modeled with full PV cells. Today, the use of half-cell modules, which is a new technology, is increasing rapidly. Although half PV cells have several advantages over full PV cells, there are also some manufacturing disadvantages. In this study, as a result of a comprehensive literature review, the parameters affecting the total efficiency of half and full cell PV modules are compared. With this comparison, it is aimed to show the advantages of half-cell PV modules over full-cells, such as low power loss, reduced shade sensitivity, high price-performance ratio, less hot spot effect and improved heat dissipation. In addition to these, information is given about the efficiency, production processes and some other disadvantages of half and full PV cells.

Yarım ve tam fotovoltaik hücreleri ile tasarlanan güneş enerjisi panellerinin toplam verimliliğini etkileyen parametrelerinin incelenmesi

Öz

Güneş enerjisi (GE), küresel çevre endişelerini azaltmak ve artan enerji talebini karşılamak için en umut verici yenilenebilir enerji kaynaklarından biri olmuştur. Güneş enerjisinden farklı şekillerde yararlanılmaktadır. Bunlardan biride fotovoltaik (PV) hücrelerdir. Fotovoltaik hücreler güneş enerjisini doğrudan elektrik enerjisine dönüştüren yarıiletken malzemelerdir. Geleneksel fotovoltaik modüller tam PV hücreler ile modellenmektedir. Günümüzde ise yeni bir teknoloji olan yarım hücreli modül kullanımı hızla artmaktadır. Yarım PV hücrelerin tam PV hücrelere göre çeşitli avantajları olmasına rağmen, bazı üretim dezavantajları da vardır. Bu çalışmada kapsamlı bir literatür incelemesi sonucu yarım ve tam hücreli PV modüllerin toplam verimliliğini etkileyen parametreler karşılaştırılarak yarım hücreli PV modüllerin, düşük güç kaybı, azaltılmış gölge duyarlılığı, fiyat performans oranının yüksek olması, daha az sıcak nokta etkisi ve iyileştirilmiş ısı dağılımı gibi tam hücrelere göre üstünlüklerinin gösterilmesi amaçlanmaktadır. Bunlara ek olarak yarım ve tam PV hücrelerinin verimlilikleri, üretim süreçleri ve diğer bazı dezavantajları hakkında da bilgiler verilmektedir.
