Abstract: | 近年來由於石油價格飆漲、傳統能源耗竭再加上環保意識抬頭,各國皆積極開發新的替代能源。太陽能是一種無污染又取之不盡的能源,自然成為許多熱門研究議題之一。
鑑於過去許多太陽能電池相關研究大多侷限於太陽光電轉換部分,而長時間受太陽日照所產生的熱能並未有效利用。本文主要利用熱電發電晶片對太陽能板上多餘的熱能進行熱電轉換,一方面可以提升太陽能板發電效率,另一方面熱電模組冷端散熱裝置可以幫助太陽能板散熱,以延長太陽能板使用壽命。最後利用太陽能板結合研究室學長自製非線性電阻脈衝充電電路,對鎳氫電池進行充電,由於脈衝式充電方式能得到適當休息時間,有效抑制電池極化現象,提升電池充電效率。 In recent years, national governments have develop a new alternative energy actively due to the soaring of oil price, the exhaustion of traditional energy and the rising consciousness of environmental protection. A solar power is an inexhaustible energy without pollution. It is therefore foreseeable that the solar energy is to be one of the most popular research issues. It is a fact that the relevant researches with the solar cell is mostly limited to the solar energy opto-electronic transformation but not to utilize the generated heat energy upon irradiation with light from the sunshine in a long time effectively. The subject matter mainly utilizes a thermoelectric generator ( TEG ) to provide with a thermoelectric conversion with superfluous heat energy insofar as a solar panel. One point is to rise a power generation efficiency of the solar panel, another point is to provide with a thermoelectric module-cold end heat dissipation means to dissipate heat thereform, so as to prolong the operating life of the solar panel. Finally, it is to utilize the solar panel to incorporate with a nonlinear resistance-pulse charging circuit to charge up a Ni-MH battery, of which is made by the research laboratory director. It can get a suitable rest time due to the pulse charging mode to suppress a polarization phenomena of the battery availably and boost a charging efficiency thereof. |
