A method for cryopreserving cells, a cell cryopreservation solution and a composition are provided. The method includes: providing a suspension for the cells to be cryopreserved in a cell cryopreservation solution; and cryopreserving the suspension. The cell cryopreservation solution includes dimethyl sulfoxide, plasma, citric acid, sodium citrate, potassium dihydrogen phosphate or sodium dihydrogen phosphate, glucose and adenine.

Cell cryopreservation solution and method for cryopreserving cells

The invention relates a full-laser scribing method for a flexible stainless steel substrate solar cell module, comprising: preparing an insulating layer and a molybdenum layer on a stainless steel substrate in sequence; using a laser I to scribe the prepared insulating layer and molybdenum layer to form a first scribed line (P); preparing the following film layers in sequence on the molybdenum layer in which Phas been scribed: a CIGS layer, a cadmium sulfide layer and an intrinsic zinc oxide layer; using a laser II to make scribe and thus form a second scribed line (P), wherein the second scribed line Pis parallel with the first scribed line P; and preparing an aluminum-doped zinc oxide layer on the intrinsic zinc oxide layer in which Phas been scribed, and using a laser III to make scribe and thus form a third scribed line (P), wherein the third scribed line Pis parallel with the first scribed line PThe invention may avoid disadvantages caused by the screen printing, such as large dead zone, expensive screen printing paste and frequent replacement of screens for screen printing, thereby improve efficiency and stability of the module and save cost and increase production efficiency.
