Öz

Termoelektrik jeneratörler (TEG'ler), yenilenebilir enerji üretimi ve atık ısı geri kazanımı için umut vadeden bir çözüm olarak giderek daha fazla ilgi görmektedir. Bu çalışma, güneş enerjisiyle ısıtma için standart vakumlu cam tüpler ve baca tipi rüzgar destekli pasif soğutma mekanizması ile 30 TEG modülünü entegre eden yeni bir termoelektrik güneş jeneratörünün tasarımını, üretimini ve performans değerlendirmesini sunmaktadır. Önerilen sistem, elektrik üretmek için doğal termal gradyanlara dayanarak, tamamen harici enerji girdisi olmadan çalışmaktadır. Deneysel sonuçlar, jeneratörün orta düzeyde güneş ışınımı altında 70 V'a kadar açık devre voltajı ve 23 W'lık tepe elektrik gücü çıkışı elde edebildiğini göstermiştir. Genel enerji dönüşüm verimliliği %8,28 olarak hesaplanmış olup, termoelektrik sistemlerin geleneksel fotovoltaik veya hibrit PV-TEG konfigürasyonlarına alternatif olarak uygulanabilirliğini göstermektedir. Sistemin ölçeklenebilirliği, özerkliği ve ısı ve güç üretimi için ikili potansiyeli, şebeke dışı ve uzak enerji çözümlerinde güçlü bir uygulanabilirlik önermektedir.

Thermoelectric Energy Conversion Solar Generator Design and Manufacturing

Öz

Thermoelectric generators (TEGs) are gaining increasing attention as a promising solution for renewable energy production and waste heat recovery. This study presents the design, fabrication, and performance evaluation of a novel thermoelectric solar generator that integrates 30 TEG modules with standard evacuated glass tubes for solar heating and a chimney-type wind-assisted passive cooling mechanism. The proposed system operates entirely without external energy input, relying on natural thermal gradients to produce electricity. Experimental results showed that the generator can achieve up to 70 V open-circuit voltage and a peak electrical power output of 23 W under moderate solar irradiance. The overall energy conversion efficiency was calculated to be 8.28%, demonstrating the viability of thermoelectric-only systems as an alternative to conventional photovoltaic or hybrid PV-TEG configurations. The system's scalability, autonomy, and dual potential for heat and power generation suggest strong applicability in off-grid and remote energy solutions.
