研究通过提高发射区的方块电阻和采用合适的工艺技术,制备了性能优良的单晶硅太阳电池。采用丝网印刷技术制备了40Ω/□常规发射区和60Ω/□高方块电阻发射区单晶硅太阳电池并对其性能进行了分析研究。扩展电阻法分析表明:60Ω/□发射区的表面活性磷杂质浓度和结深比40Ω/□发射区的分别降低了12.8%和14.9%。尽管60Ω/□发射区太阳电池的串联电阻增加了0.141Ω/cm2导致填充因子下降了1.24%,但是短路电流密度和开路电压分别提高了1.31 mA/cm2和1.2 mV,最终转换效率仍然提高了0.4%。 相似文献

Anti-reflection coating (ARC) film effectively reduces the reflection of sunlight on the silicon wafer surface and then increases substantially the solar cell conversion efficiency. In this work, we carried out experiments to lessen the reflectance and thus improve the conversion efficiency with double AR coating layer with silicon nitride and silicon oxide by plasma enhanced chemical vapor deposition (PECVD) for the silicon solar cells. The optimized thicknesses and refractive indices of each ARC layer were calculated with Essential Macleod program and the theoretical method. The single antireflection layer of silicon nitride was applied with 800 Å thickness and its cell showed the conversion efficiency as 17.45 %. For the double layer AR coating (DLARC), silicon nitride layer was deposited first using SiH4 and NH3, and then, silicon oxide was deposited with SiH4 and N2O. The thicknesses of SiNx and SiO2 were 800 Å and 1400 Å for DLARC-1 and 500 Å and 1000 Å for DLARC-2, respectively. As a result, the reflectance of DLARCs was lower than single SiNx and then yielded increase of short-circuit current and conversion efficiency. The completed solar cell with DLARCs showed conversion efficiencies of 17.57 % for DLARC-1 and 17.76 % for DLARC-2. This indicates that the double AR coating layer is effective to obtain the high efficiency solar cell with PECVD. 相似文献

This paper analyzes influence of resource allocation in R&D of solar cells in Japan. First, it estimates solar cell price in Japan in the case resource allocation for R&D of crystalline silicon solar cells was not significantly reduced, but maintained almost constant level. For the projection, it does not use experience curve, but models technological progress, price reduction, of solar cell in Japan with a variable technology knowledge stock by excluding mass production effects. Second, solar cell prices in other countries are estimated based on their market share in the global solar cell production. The estimated solar cell price in Japan under the assumed resource allocation decreases by about 30% compared to the actual one and it, therefore, could be competitive to the estimated solar cell prices in China and Taiwan. In this case, Japan could maintain its top market share in the global solar cell production several years longer. Instead of the Japan's Feed‐in Tariff with subsidy, net‐metering without subsidy is enough for keeping almost the same internal rate of return of residential PV systems for new and existing houses. This paper will be helpful to cost‐effective R&D planning by a modeling and simulation approach. 相似文献
