“…Walau bagaimanapun, sel suria jenis silikon monohablur paling banyak digunakan dalam semikonduktor dengan kadar kecekapan sel PV kategori tersebut sebanyak 24.7%. Sel suria jenis multihablur pula mempunyai kadar kecekapan penukaran tenaga di antara 10% hingga 14% seperti yang dinyatakan oleh Hermann (1998).…”

Photovoltaic-thermal (PVT) collectors were developed by combination of photovoltaic (PV) panel and thermal collector. The combination of technologies in one system has the potential to reduce cost of materials, required space and also improves performance of collectors. The PVT collectors will produce electrical and thermal energy simultaneously. PV technology converts solar radiation into electricity while thermal collector will be converting solar energy to thermal energy. The main components of PVT collectors are PV panel, absorber plate, heat transfer fluid and insulator. Based on previous studies, PVT collectors were developed by using air, water and nanofluid as a heat transfer medium. The function of heat transfer process is to improve PV panel efficiency by removing excessive heat from module and at the same time generating thermal energy. In addition, the parameters that affecting PVT's performances are including; mass flow rate of the fluid, area of collector, solar radiation and PV cell materials used. The overall performances of PVT collectors are depending on the electrical and thermal energy efficiencies. Therefore, the main objectives of this paper are to analyze energy and exergy efficiencies of PVT collector with different designs and types of working fluid. The performances were studied using concept of energy balance and exergy entropy analysis. Result has shown that energy and exergy efficiency are in the range of 40-75% and 5-25%, respectively. ABSTRAKPengumpul suria hibrid fotovoltan-terma (PVT) dibina dengan menggabungkan panel fotovoltan (PV) dengan pengumpul terma. Dengan kombinasi dua teknologi ini dalam satu sistem yang sama boleh mengurangkan kos bahan, menjimatkan ruang dan meningkatkan prestasi pengumpul. Pengumpul PVT dapat menghasilkan tenaga elektrik dan tenaga terma secara serentak. Teknologi PV akan menukarkan radiasi suria kepada tenaga elektrik manakala pengumpul terma akan menukarkan tenaga suria kepada tenaga terma. Komponen utama dalam membangunkan pengumpul PVT adalah panel PV, plat penyerap, bendalir pemindahan haba dan penebat. Berdasarkan kajian penyelidik terdahulu, PVT dibina dengan menggunakan udara, air atau bendalir nano sebagai medium pemindahan haba. Fungsi proses pemindahan haba adalah untuk meningkatkan kecekapan panel PV dengan memindahkan haba berlebihan daripada modul dan dalam masa yang sama menjana tenaga terma. Tambahan, parameter-parameter yang memberi kesan kepada prestasi pengumpul PVT adalah termasuk; kadar aliran jisim bendalir, luas pengumpul, radiasi suria dan jenis bahan sel PV yang digunakan. Kecekapan keseluruhan pengumpul PVT bergantung kepada kecekapan tenaga elektrik dan tenaga terma. Justeru itu, objektif utama kertas ulasan ini adalah untuk menganalisis kecekapan tenaga dan eksergi bagi pengumpul PVT dengan reka bentuk dan jenis-jenis bendalir kerja yang berbeza. Kecekapan dinilai berdasarkan konsep keseimbangan analisis tenaga dan entropi eksergi. Dapatan hasil menunjukkan kecekapan tenaga dan tenaga eksergi dalam julat sekitar 40-75%, dan...

“…Cadmium telluride and amorphous Si and other thin film materials are also good candidates [27–30] . Modules of the second generation solar cells have been also marketed but they did not gain the success of the first generation solar cells, due to technological problems and module stability [31] . Losses due to polycrystallinity of thin films were investigated.…”

“…It was reported that there were no clear dominant losses for Cu(In, Ga)Se 2 or CdTe solar cells and it was suggested to incorporate impurities into the absorber like Na in both Cu(In, Ga)Se 2 and CdTe and to use anti-reflection coatings. Significant problems must be solved prior to large scale development of polycrystalline thin film devices [31,32] . Photovoltaic structures based on polymer/semiconductor junctions have been also investigated.…”

“…CuInS 2 thin films have an edge over all other photovoltaic material because it has an optimal band gap of 1.5eV, which is necessary for maximum absorption of the solar spectrum. There are several reports on synthesizing CuInS 2 using different techniques for fabricating solar cells and some of the cells exhibited efficiency of the order of 12% [1][2][3][4][5]. Our group recently reported an all sprayed CuInS 2 /In 2 S 3 thin film solar cell with an efficiency of 9.5% [6].…”
