Effect of Ambient Conditions on Monthly Performances of Three Different PV Arrays

Solar PV cells may be mainly divided into two parts as crystalline and thin film. Mono-crystalline silicon (MonoSi), microcrystalline based amorphous silicon (a-Si/µc-Si) thin film and Cadmium Telluride (CdTe) thin film solar cells are widely used PV cells in the arrays. The outdoor performances of the systems depend on some climatic parameters and conditions, and it is important to understand how the monthly efficiencies vary with these parameters (Bhattacharya et al., 2014; Dubey et al., 2013; Skoplaki and Palyvos, 2009). In the present study, the data obtained from three grid connected PV arrays of Mono-Si, a-Si/µc-Si and CdTe thin film that were operated for 3 years in Ankara-Turkey is analyzed. The results showed that Mono-Si array performance depends on the outdoor climatic conditions while a-Si/µc-Si and CdTe thin film arrays performances are not significantly affected by the variation of the climatic parameters.


Effect of Laser Parameters and Post-Texturing Treatments on the Optical and Electrical Properties of Laser Textured c-Si Wafers
RADFAR, Behrad; ES, FIRAT; NASSER, Hisham; AKDEMİR, Ozan; Bek, Alpan; Turan, Raşit (2018-03-21)
Surface plays a crucial role in the performance of crystalline silicon (cSi) based solar cells as it affects both electrical and optical properties. To minimize reflection from the flat surface and thus improve light trapping, the cSi wafers must be textured. For mono-cSi cells, anisotropic alkaline etchants are commonly utilized to create pyramids on the surface. However, this method is not viable for multi-crystalline silicon (mc-Si) wafers due to the presence of different and random crystallographic orie...
Optical and electrical design guidelines for ZnO/CdS nanorod-based CdTe solar cells
Özcan, Can; Turkay, Deniz; Yerci, Selçuk (2019-04-15)
An alternative structure to planar CdTe solar cells is realized by coating ZnO/CdS nanorods (NRs) with a CdTe layer. These structures are expected to achieve high-powered conversion efficiencies through enhanced light absorption and charge carrier collection. ZnO NR-based CdTe solar cell efficiencies; however, they have remained well below their planar counterparts, thus hindering NRs in CdTe solar cells' advantages. Here, we analyze the light trapping and carrier collection efficiencies in two types of ZnO...
Effects of different laser modified surface morphologies and post-texturing cleanings on c-Si solar cell performance
Radfar, Behrad; ES, FIRAT; Turan, Raşit (Elsevier BV, 2020-01-01)
Performance of crystalline Silicon solar cells depends on numerous factors. One key factor is a surface structure which can restrict electrical and optical properties due to recombination of generated carriers and reflection of incident light. Surface texturing reduces reflection from a flat surface which increases absorption of light. Anisotropic alkaline etchants are commonly used for texturing mono-crystalline Silicon wafers which produce pyramid structures on the surface. Because of randomly oriented cr...

Gözenekliliğin, 20 nm ve 200 nm TiO2 partiküllerinin farklı oranlarda karıştırılmasıyla oluşturulan pastalar kullanılarak hazırlanan boyaya duyarlı güneş pillerinin (DSSC'ler) enerji dönüşüm verimine etkisi araştırılmıştır. Macunların mikroyapısını incelemek için XRD ve SEM analizleri yapılmıştır. DSSC'lerin enerji dönüşüm verimliliği, tam akım yoğunluğu-voltaj eğrisi çizilerek belirlendi. Ağırlıkça% 40 20 nm ve ağırlıkça% 60 200 nm TiO2 partiküllerinden oluşan karışım kullanılarak hazırlanan DSSC,% 6.74'lü...
Comparison of crystal Si solar cells fabricated on p-type and n-type float zone silicon wafers
Bilgen, Makbule; Turan, Raşit; Department of Physics (2013)
Solar cells are traditionally fabricated on p-type Si substrates due to the high electron diffusion length in p-type substrate. However, high quality float zone silicon wafers provide higher carrier life time for holes in the n-type substrates, making it possible to fabricate high efficiency solar cells in this type of substrate. Superior properties of n-type substrates have created a tendency towards fabrication of n-type solar cells in photovoltaic market technology considerably. It is even forecasted tha...
