Description
Technical field
The invention belongs to solar cell material technical field, be specifically related to a kind of crystal silicon solar energy battery front side silver paste
With glass dust and preparation method thereof.
Background technology
The energy of shortage has had a strong impact on life and the development of restriction society of people.Abundant solar energy is important clear
The clean energy, is the energy that can freely utilize of inexhaustible, nexhaustible, pollution-free, cheap, the mankind.The first oil crisis
Afterwards, various countries competitively carry out cleaning and the applied researcies of regenerative resource, especially solar energy such as solar energy, water energy, wind energy
Applied research is the most extensive.
Solar energy does not has any nonstaining property as a kind of green energy resource to environment, and its source is simple, it suffices to say that
It is that it is inexhaustible in the existence time limit of the mankind.Solar energy is not only the disposable energy, or cleaning energy
Source, its aboundresources, generally exist, without transporting, also can freely use, the most important thing is environment is not had any pollution.Too
Sun also can have the advantage not available for other generation modes many because of the particularity of solar energy by battery: without geographical restrictions, no
Consume fuel, scale is changeable, motility is big, pollution-free, noiselessness, safe and reliable, the construction period is short, safeguard simply,
There is the probability of large-scale application.So a lot of experts go solar energy to exploitation as the alternative energy, it is desirable to too
Sun can be brought benefit to the mankind.Nowadays the solar energy used have greatly by solar cell conversion get.Because
Solaode has sensing to light, it is possible to the luminous energy being radiated at its surface is converted to electric energy.At present, in the effort of relevant expert
Under, solaode is own through having moved towards commercialization and industrialization.
Glass dust determines sintering peak temperature as high temperature viscous energy phase, its softening temperature.Glass dust is to silicon substrate and metal
The wettability of powder is the most helpful to the burn-back intensity of film layer, and good wettability is good, and the dry of film layer just connects intensity
Height, vice versa.The thermal coefficient of expansion of the low flame glass of electric slurry is a kind of match parameter, crosses senior general and causes crystalline silicon electricity
Pond sheet wing Qu Yanchong, typically requires the close of thermal coefficient of expansion and silicon substrate, the most identical.Thermal coefficient of expansion does not mates, and burns
The cell piece performance obtained after knot will have the biggest thermal stress, and cell piece has bigger thermal shock, big heat during operation
Stress is likely to result in battery leafing until losing efficacy.Glass generates liquid phase in sintering process as high temperature bond and moves
Move, can carry in this process and carry out migrating and moistening with coated metal granule, and then promote metallic particles sintering densification.
Charging used by the silver electrode silk screen printing of crystal silicon solar batteries front is with superfine high-purity argentum powder for main body filler, with a definite proportion
The collocation of the glass dust of example, organic carrier is formulated, and in the many factors affecting solar cell properties, glass dust is one
Crucial factor, it directly affects the electric property of solaode, especially affects its series resistance (Rs), and then have influence on
The photoelectric transformation efficiency of battery.Can be formed well with silicon chip this is because series resistance depends mainly on the size of front side silver paste
Ohmic contact, and glass dust play in Ohmic contact key effect.Up to the present, both at home and abroad to the applicable sun
The research of the glass dust of energy battery front side snow cover is the most less, and system not is with deep.
