Solution-processed Cu（In,Ga）Se2（CIGS） solar cells suffer from serious carrier recombination and power conversion efficiency（PCE） loss because of the poor film properties and easy formation of ***, we propose Ag&Se co-selenization strategy to enhance the crystallization and passivate harmful defects of the CIGS films. The formation of Ag-Se phase during the selenization process enables the formation of large grains and suppresses the deep level defects. It is found that Ag doping can enlarge the depletion region width, lower the Urbach energy and prolong the carrier lifetime. As a result, a champion solution-processed CIGS solar cell presents a high efficiency of 16.48% with the highly improved opencircuit voltage（VOC） of 662 m V and fill factor（FF） of 75.8%. This work provides an efficient strategy to prepare high quality solution-processed CIGS films for high-performance CIGS solar cells.

为准确计算采用均压防治外部漏风时调压风机的压力,研究了基于矿井风网解算的均压通风计算模型。通过对均压通风原理及其在矿井内、外部漏风防治中技术特点的分析,结合通风网络解算原理,建立了均压防治外部漏风的计算模型,其计算结果显示调压风机升压力取决于矿井通风阻力的分布。依据红柳林矿井浅埋开采形成的采空区外部漏风现场观测数据,评估了漏风对矿井通风系统稳定性的影响,并设计了调压风机与风窗联合的均压通风方案。该方案采用网络解算软件计算了15207采煤工作面采空区外部漏风分支风阻与进风段通风阻力,确定了调压风机升压值与风窗的控风参数,实施后取得了预期效果。现场的成功应用表明了此技术的正确性,对同类矿井具有借鉴意义。
