Son yıllarda, güneş enerjili termoelektrik jeneratörler diğer yeşil güç üretim sistemleri arasında umut verici bir konu olarak ortaya çıkmıştır. Geleneksel enerji üretim sistemlerindeki gibi bir ara enerji formu olmaksızın güneş enerjili termoelektrik jeneratör doğrudan güneş enerjisinden elektrik enerjisi üretebilen bir sistemdir. Güneş enerjili termoelektrik jeneratördeki son gelişmelerle, konsantre sistemler gibi optimize edilmiş sistemlerin ve ayrıca nanoteknolojinin sağladığı desteklerin bir sonucu olarak çeşitli iyileştirmeler sağlanmıştır. Bu çalışmada, baz akışkan olarak su içinde dağıtılan Grafen Nanoplateletler (GNP’ler) ve Çok Duvarlı Karbon Nanotüpler (MWCNT’ler) kullanan bir yoğunlaştırıcı termoelektrik jeneratör (CTEG) deneysel olarak incelenmiştir. Karabük Üniversitesi laboratuvarlarında yoğunlaştırıcı termoelektrik jeneratör sistemi (CTEG) tasarlanıp, imalatı gerçekleştirilmiş ve dış şartlarda deneyler yapılmıştır. Deneyler, MWCNTs-Su ve GNPs-Su nanoakışkanlarının ağırlıkça %0.25 nanoparçacık kütle konsantrasyonu için sabit debide (ν ̇=0.5 L/dk) gerçekleştirilmiştir. Deneylerde termal ve elektriksel enerji verimliliği üzerindeki nanoparçacık tipinin etkisi amaçlanmıştır. Elde edilen sonuçlar, CTEG sisteminin 38°C’lik bir ortalama sıcaklık farkı için maksimum 3.7 W elektrik gücü çıkışı üretmeye olanak sağladığını göstermiştir. Elektrik performansı için MWCNTs-su nanoakışkanın artış oranı diğer akışkanlara göre daha büyükken GNP’ler-su nanoakışkanın termal performansı maksimum artışı göstermiştir. Günlük toplam verim değerleri saf su, GNPs-su, MWCNTs-su için sırasıyla %16.34, %24.03 ve %20.21 olarak hesaplanmıştır. Çalışmanın sonuçları, CTEG uygulamalarındaki soğutma tekniği için farklı türlerde nanoakışkanların kullanımının potansiyel seçeneklerden biri olma beklentileri hakkında sağlam bir temel oluşturmuştur.

“…In PV‐TEG cooling, the TEG is always underutilized as the temperature difference observed is less (≈3°C), which leads to very low efficiency (<1%). Hence, as reported earlier, 28,29 in‐field application of PV‐TEG combination must be rethought. Compared to conventional PV‐TEG hybrid system, TEG with concentrated PV is justified as reported in the literature 57‐59 …”

Numerous studies have emphasized the role of cooling in maximizing the energy conversion efficiency of a photovoltaic (PV) module. Amongst them, the energy and exergy analyses of PV-thermoelectric generator (PV-TEG) hybrid systems with evaporative cooling have been rarely investigated. Hence, the present experimental study focuses on the performance comparison of PV-TEG hybrid system with different cooling techniques. The parameters studied are panel temperature, energy and exergy efficiency, power output, and I-V and P-V characteristics. As the indoor and outdoor radiation spectrum varies

“…Bellos & Tzivanidis (2019) tested experimentally the effect of using cooling by water and nanofluids Al2O3 in photovoltaic thermal system. The maximum performance of electric and thermal were 13% and 65% for photovoltaic module without cooling, and 11.47% and 56.08% for the CPVT-TE with 0.5 percent graphene/water nanofluid and CPVT-TE compared to CPVT collector are 11.15 percent and 9.77 percent for the summer day (Rejeb et al, 2021). Tested The effect of cooling CPV-T spectral splitting by used nanofluid.…”

In a Fresnel-based Concentrated Photovoltaic system, multi junction solar cells suffer from increased PV temperature, resulting in a decrease its electrical efficiency. This study design to investigate the influence of using Water/Al2O3 Nanofluid as cooling fluid on heat transfer enhancement and top surface temperature for multi-junction solar cell in the Fresnel-based Concentrated Photovoltaic thermal CPVt System. The CFD simulation was conducted on mini-channel under the concentrated multi-junction solar cell with using water/Al2O3 Nanofluid and pure water as coolant fluids. The Reynolds number is in the range of 15000-30000 were examined. The average Nusselt numbers augmented through increasing Reynolds numbers. The water/Al2O3 Nanofluid provides highest heat transfer enhancement of 23% compare with water in Fresnel-based CPVt system. The top surface temperature decreases as Nusselt number increases. The Nuavg improves 21% with using of water/Al2O3 Nanofluid at lowest Reynolds number of 15000 and 23% at highest Reynolds number of 30000.The top surface temperature dropped from 337K to 327K at lowest Reynolds number of 15000 with using Water/Al2O3 Nanofluid as cooling fluid and from 323K to 315K at highest Reynolds number of 30000.This study has confirmed that the use of water/Al2O3 Nanofluid has significant influence on the dissipate the heat from Multi-Junction Solar Cell in Fresnel-based CPVt system which led to improve its electrical efficiency.
