Definitions
- the present invention relates to a chalcopyrite solar cell comprising a substrate and a photovoltaic layer structure.
- a chalcopyrite solar cell comprising a substrate and a photovoltaic layer structure.
- it is a thin-film solar cell with a photovoltaic layer structure of the copper-indium-sulfide (CIS) or copper-indium-gallium-selenide (CIGSe) type.
- CIS copper-indium-sulfide
- CGSe copper-indium-gallium-selenide
- the invention relates to a process for the preparation of solar cells based on chalcopyrite.
- the solar cell is equipped with an encapsulation layer, which is prepared by curing a solution of
- Polysilazanes and additives at a temperature in the range of 20 to 1000 0 C, in particular 80 to 200 0 C is generated.
- Solar cells convert sunlight into electricity.
- Predominantly crystalline or amorphous silicon is used as a light-absorbing semiconductive material in solar cells.
- the use of silicon is associated with considerable costs.
- thin film solar cells can be made with an absorber of a chalcopyrcrical material such as copper indium sulfide (CIS) or copper indium gallium selenide (CIGSe) at a substantially lower cost.
- CIS copper indium sulfide
- CGSe copper indium gallium selenide
- the efficiency of a solar cell is defined as the ratio of electrical power, ie the product of voltage and photocurrent, to incident light power.
- the efficiency is proportional to the number of photons that can penetrate into the absorber layer and contribute to the generation of electron-hole pairs.
- Photons, which are reflected on the surface of the solar cell do not contribute to the photocurrent. Accordingly, the efficiency can be reduced by a reduction the light reflection at the surface of the solar cell can be increased.
- the lifetime of solar cells can be extended by improved protection against weather-related degradation processes. Penetrating water or water vapor accelerates the degradation processes.
- the prior art therefore uses an encapsulation of a layer composite which comprises glass and EVA and optionally PVA and other polymer films.
- SiO x layers are deposited from the gas phase by CVD methods such as microwave plasma assisted vapor deposition (MWPECVD) and PVD methods such as magnetron sputtering. These vacuum techniques are associated with high costs and also have the disadvantage that the layers produced therewith a low
- CVD processes also require the use of highly flammable (SiHU, CH 4 , H 2 ) and toxic (NH 3 ) gases.
- Glass As substrate materials for chalcopyrite solar cells glass or films of metal or polyimide are used. Glass proves to be advantageous in several respects because it is electrically insulating, has a smooth surface and, during the production of the chalcopyrite absorber layer, provides sodium, which diffuses out of the glass into the absorber layer and serves as dopant Properties of the absorber layer improved.
- a disadvantage of glass is its great weight and lack of flexibility.
- glass substrates can not be coated in cost-effective roll-to-roll processes because of their rigidity.
- Film-like substrates made of metal or plastic are lighter than glass and flexible, so that they are suitable for the production of solar cells by means of a cost-effective roll-to-roll process.
- metal or plastic films may adversely affect the property of the chalcopyrite layer composite and, moreover, do not have a sodium depot for absorber doping. Because of the elevated temperatures (in some cases above 500 ° C.) to which the substrate is exposed during the production of the solar cells, metal foils of steel or titanium are preferably used.
- the photovoltaic layer structure or the back contact must be electrically insulated from the substrate film.
- Substrate film applied a layer of an electrically insulating material.
- This electrically insulating layer should also act as a diffusion barrier to prevent the diffusion of metal ions that can damage the absorber layer.
- metal ions For example, iron atoms can increase the recombination rate of charge carriers (electrons and holes) in chalcopyrite absorber layers, thereby decreasing the photocurrent.
- the material used for insulating and diffusion-inhibiting barrier layers is silicon oxide (SiO x ).
- protective or encapsulation layers which essentially consist of SiO x or SiN x , for electronic components and solar cells based on silicon or other semiconductor materials.
- US 7,067,069 discloses an insulating encapsulation layer of SiO 2 for silicon-based solar cells, wherein the SiO 2 layer is produced by applying polysilanes and subsequent curing at a temperature of 100 to 800 0 C, preferably from 300 to 500 ° C.
- US Pat. No. 6,501,014 B1 relates to articles, in particular solar cells based on amorphous silicon, having a transparent, heat-resistant and weather-resistant protective layer of a silicate-like material.
- the protective layer is easily produced by using a polysilazane solution. Between the protective layer based on polysilazane and the photovoltaic layer system, a flexible rubber-like adhesive or buffer layer is arranged.
- No. 7,396,563 teaches the deposition of dielectric and passivating polysilazane layers by means of PA-CVD, wherein polysilanes are used as CVD precursor.
- US 4,751,191 discloses the deposition of polysilazane layers for solar cells by means of PA-CVD.
- the resulting polysilazane layer is patterned photolithographically and serves to mask metaiischen contacts as well as antirefiex harsh.
- the solar cells described in the prior art with encapsulation layers of SiO x or SiN x are expensive to produce and require the use of two- or multi-layer composite layers, which comprise a carrier film, a buffer layer, a primer layer and / or a reflector layer in addition to the encapsulation layer.
- buffer layers are required which compensate for the thermal mismatch with the encapsulation layer. Thermal mismatch, ie differences in the coefficient of thermal expansion of adjacent layers, induce mechanical stresses that often lead to cracking and peeling.
- this problem is counteracted by the fact that the encapsulation layer is deposited on the solar cell at low temperatures.
- such low-temperature encapsulant layers usually have insufficient barrier to water vapor and oxygen.

- FIG. 2 shows the results of a measurement of the spectral reflectivities of a chalcopyrite solar cell with and without a polysilazane-based encapsulation layer according to the invention (denoted in FIG. 2 by a solid "with SiO x " and a dashed line "without SiO x ").

- the efficiency of chalcopyrite solar cells drops with increasing temperature. Due to increased reflectivity for infrared light, the encapsulation layer according to the invention reduces the heating of the solar cell caused by solar radiation and thus also contributes to an improvement in the efficiency in this way. In the wavelength range of 1100 to 1500 nm, the solar cell according to the invention has an average relative reflectivity of greater than 120% to more than 200%.
