Abstract
The invention discloses an additive for crystalline silicon solar cell wool-making agent. The additive is prepared from the following components: sorbitol, phosphoric acid, sodium citrate and deionized water. Compared with the prior art, the additive for the crystalline silicon solar cell wool-making agent has the advantages as follows: the additive is non-toxic and non-corrosive, simple in formula and harmless to human body; the wool-making temperature is reduced, and the wool-making time is shortened; the formed wool surface is fine and uniform in dimension.
Description
?
Technical field
The present invention relates to the additive in a kind of solar battery slice etching operation, especially a kind of crystal silicon solar cell sheet making herbs into wool additive.
Background technology
Sun power is a kind of cleaning, sustainable energy, solar photovoltaic technology then is the important channel that utilizes sun power, it not only can be converted into electric energy with sun power, and no any mechanical movement in the switching process, therefore, used widely, and crystal-silicon solar cell is the leading role in photovoltaic power generation technology field.The developing direction of crystal-silicon solar cell is to reduce cost and improve photoelectric transformation efficiency.In the solar battery sheet preparation process, in order to improve Solar cell performance and efficient, need make matte at silicon chip surface, effectively suede structure can be so that the incident sunlight repeatedly reflects and reflect the working direction of change incident light in silicon at silicon chip surface.On the one hand, prolong light path, thereby strengthened the specific absorption of silicon chip to infrared light; On the other hand, make more photon be absorbed the generation photo-generated carrier near near the zone the PN junction, these photo-generated carriers are easier to be absorbed, and therefore, has increased the collection effciency of photo-generated carrier.
Summary of the invention
The object of the present invention is to provide a kind of crystal silicon solar cell sheet making herbs into wool additive.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of crystal silicon solar cell sheet Wool-making agent additive is characterized in that it is formulated by following component: sorbyl alcohol, phosphoric acid, Trisodium Citrate and deionized water.
The mass percent of component of the present invention is: sorbyl alcohol 10-25%, phosphoric acid 8-30%, Trisodium Citrate 20-30%, surplus are deionized water.
The mass percent of component of the present invention is: sorbyl alcohol 15-20%, phosphoric acid 8-20%, Trisodium Citrate 20-30%, surplus are deionized water.
Compared with prior art, the present invention has the following advantages: this additive is nontoxic, non-corrosiveness, prescription are simple, harmless; Reduce the making herbs into wool temperature, shorten the making herbs into wool time; The matte size that forms is tiny evenly.
