| Summary: | 碩士 === 雲林科技大學 === 環境與安全工程系碩士班 === 98 === This research collected the daytime weather data in 2008. The data were used to investigate the energy efficiency and the payback period from high concentrator Ga-As(III-V) and silicon-base solar cells for power generation systems.
According to the historical weather data, Found that high concentrator Ga-As(III-V) of solar power systems in various parts of the total generating capacity was 3,890.7 (KWH / year), 5,164.5 (KWH / year), 5,102.7 (KWH / year), 5,429 (KWH / year) are higher than silicon-base solar cells for power generation systems. In the power generation cost, high concentrator Ga-As(III-V) of regional 1KWH average tariff was NT$5.98.
High concentrator Ga-As(III-V) set-up costs than silicon-base solar cells. leading to an electricity and higher cost recovery period. After deducting 50% of government subsidies, high condenser type III-V family for 23 years before they can be recycled, single crystal silicon Zexu 17 years. If the assessment of the cost recovery period back to sell the two were reduced to 11 years and 9 years to recover. The contribution in terms of carbon dioxide reduction. high concentrator Ga-As(III-V) average to CO2 254.23 kg reduction. silicon-base solar cells the average CO2 reduction of 156.82 kg. Display high concentrator Ga-As(III-V) considerable reduction potential.
