In the third chapter, the influence of current density, solution concentration, erosion time and aging in ambient air on the pl spectra of ps suggests that peak would blue shift with current density increasing, and with erosion time and aging time prolonging ; with the increasing of solution concentration, peaks would red shift when solution concentration less than 1 : 1 but blue shift when solution concentration greater than 1 : 1. above phenomena can be explained by quantum confinement and light center model, but do not deny the action of si - h bonding and defect on the surface in the process of photoluminescence. at present, radiation mechanism is still one of the primary problems in the study of ps
在第z三章中；通過對比，分析了電流密度、陽極化時間、溶液濃度以及自i然氧化時間對多孔硅光致發光光譜的影響，認為在一定的范圍內，多i孔硅的發光峰位會隨電流密度的增大而藍移，要獲得較強的發光，需z要選擇合適的電流密度；隨著腐蝕時間的延長，多孔硅的發光峰位會i發生藍移；當f酸的濃度較小q ： 1 ）時，峰位隨濃度的增大表現為向i低能移動；而當f酸的濃度較大河山時，峰位隨濃度的增大則表現z為移向高能；多孔硅在空氣中自然氧化；其發光峰位發生藍移，而強i度隨放置時間的延長而降低。 -

As a result 4 the rising annealing temperature induces si02 phase to form, also ivolves the formation of a si phase. in high - temperature - annealed sio ~, films the excess silicon atoms are present as si - si4 tetrahedra, randomly dispersed in the amorphous si02 matrix. photoluminescent spectra were observed for the samples excided by the laser whose wavelength is 365nm. the pl peak is located at about 445nm, which dose n ' t shift as the annealing temperature changes. as the annealing temperature is raised, the luminescent intensity increases. the phenomena suggest that the si - o - si bond as a defect center which is broken down by the stress at the si nc / si02 interface is the primary source of blue luminescence
這個陡的界面由於明顯的晶格結構的差別而有較大的應力。界面的形成伴隨著界面發光中心的增加，同時pl強度在l戶800有一個大的增強。這個結果提示我們，界面上h 0 s工鍵斷裂形成的nbohc應是藍光發射的主要原因。 -
In this part, the issues and mechanism of light degradation of b - doped p - type cz - si solar cells are introduced firstly, it was clarified that boron and interstitial oxygen are major components of defect center for light degradation of b - doped cz - si solar cells. then in the experiment the b - doped cz - si is chosen as the substrates and annealled at different temperature
