池效率目前达到9.13%,利用三步共蒸发法制备的CIGS太阳电池效率达到12.1%.在各种CIS制备方法中,溅射,真空蒸镀等物理气相沉积法(PVD)需要昂贵的真空设备和复杂的制备工艺,限制了该类方法的大规模应用.电沉积法由于具有非真空,廉价,简便,高效等优点,得到了广泛研究,并成为一种极具发展潜力和竞争力的CIS薄膜制备方法[17-20]. 目前采用电沉积法制备CuInSe2薄膜主要存在成分偏离理想化学计量比严重,膜层质量较PVD法差等问题,这使得基于电沉积的CIS或CIGS薄膜太阳电池效率较低,阻碍了该电沉积法的推广和应用.针对这些问题,本文作者以采用电沉积法制备太阳电池用黄铜矿结构CuInSe2薄膜为目标,在确定合适的沉积电位范围和硒化退火温度的基础上,研究了沉积电位和电解质浓度对薄膜的物相组成,组织形貌与化学成分的影响规律,以探求高质量的太阳电池用CuInSe2薄膜的制备工艺,推动......
,典型例子如固体火箭发动机喷管喉衬[1-2],姿轨控卫星发动机用喷管[3],破甲弹药型罩[4],稀土,有色金属冶炼及石英玻璃熔炼用坩埚[5]及感应炉用发热体[6]等.就目前的技术水平而言,薄壁或复杂形状钨构件的制备技术是国际上公认的难题,传统的方法包括化学气相沉积(CVD)[7-8],物理气相沉积(PVD)[9],自蔓延高温合成(SHS)[10],粉末冶金(PM)[11-12]等.PM法冷压生坯相对密度仅为60%~65%[13-14],后续高温烧结过程中体积收缩高达30%~40%,导致薄壁或复杂形状零部件产生严重变形,开裂或崩塌等问题.而CVD,PVD,SHS等方法则生产周期长,成形效率低,加工成本十分昂贵.材料科学的发展迫切需要新的成形与加工手段的跟进,等离子喷涂成形技术因其喷射温度高达10 000 ℃以上,喷射速度达300~400 m/s[15],非常适合钨基难熔金属粉末熔化粘结成形.等......
