钙钛矿电池生产工艺流程
英文回答：
The production process of perovskite solar cells
involves several key steps. First, a transparent conductive
oxide (TCO) layer is deposited on a glass or flexible
substrate. This layer serves as the bottom electrode of the
cell. Common TCO materials include indium tin oxide (ITO)
or fluorine-doped tin oxide (FTO).
Next, a perovskite layer is formed on top of the TCO
layer. This layer is typically made by spin-coating a
precursor solution onto the substrate. The solution
contains lead halide salts, organic halide additives, and a
solvent. The substrate is then heated to evaporate the
solvent and initiate the crystallization of the perovskite
material.
After the perovskite layer is formed, a hole transport
layer (HTL) is deposited on top. This layer helps to
extract positive charges (holes) from the perovskite layer
and transfer them to the top electrode. Common HTL
materials include poly(3,4-
ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS)
or spiro-OMeTAD.
Finally, a top electrode is added to complete the
device. This electrode can be made of a metal such as gold
or silver, or a conductive polymer material. The top
electrode collects the electrons generated by the
perovskite layer and completes the electrical circuit.
Throughout the production process, various
characterization techniques are used to assess the quality
of the perovskite solar cells. These techniques include X-
ray diffraction (XRD) to determine the crystal structure of
the perovskite material, scanning electron microscopy (SEM)
to examine the morphology of the layers, and current-
voltage measurements to evaluate the device performance.

钙钛矿电池的生产工艺流程包括几个关键步骤。首先，在玻璃
或柔性基板上沉积一个透明导电氧化物（TCO）层，该层作为电池的
底电极。常见的TCO材料包括铟锡氧化物（ITO）或氟掺杂锡氧化物
（FTO）。
接下来，在TCO层上方形成一个钙钛矿层。通常，通过旋涂一
种前驱体溶液到基板上来制备该层。该溶液含有铅卤化物盐、有机
卤化物添加剂和溶剂。然后，加热基板以蒸发溶剂并启动钙钛矿材
料的结晶。
钙钛矿层形成后，上面沉积一个空穴传输层（HTL）。该层有助
于从钙钛矿层中提取正电荷（空穴）并将其传输到顶电极。常见的
HTL材料包括聚（3,4-乙二氧基噻吩），聚苯乙烯磺酸盐
（PEDOT:PSS）或spiro-OMeTAD。
最后，添加一个顶电极以完成器件。该电极可以由金或银等金
属，或导电聚合物材料制成。顶电极收集钙钛矿层产生的电子并完
成电路。
在整个生产过程中，使用各种表征技术来评估钙钛矿太阳能电
池的质量。这些技术包括X射线衍射（XRD）用于确定钙钛矿材料的
晶体结构，扫描电子显微镜（SEM）用于检查层的形貌，以及电流-
电压测量用于评估器件性能。
