First Embodiment

1 is a cross-sectional view of a thin film solar module according to a first embodiment of the present invention.

Referring to FIG. 1, the thin film solar cell according to the first exemplary embodiment of the present invention includes a flexible substrate 100, a photovoltaic layer 200 stacked on the flexible substrate 100, and a photovoltaic layer ( A front sheet 400 stacked on the first electrode, a photoactive layer, and a second electrode) 200, and a back sheet 600 formed on the rear surface of the flexible substrate 100. However, the first encapsulant 300 is included between the photovoltaic layer 200 and the front sheet 400, and the second encapsulant 500 is also included between the photovoltaic layer 200 and the back sheet 600. can do.

The flexible substrate 100 may be a transparent substrate or an opaque substrate. The substrate 100 may be an insulating transparent substrate. When the photovoltaic module according to the embodiment of the present invention performs photoelectric conversion by light irradiated from the front sheet 400 side, the substrate 100 may be an opaque insulating substrate.

The transparent substrate may be a substrate including a FEP resin, a transparent polyimide substrate, or a flexible glass substrate.

As the opaque substrate, a metal foil may be used, and as the metal, aluminum (Al), stainless steel (SUS), cold rolled steel sheet, or the like may be used. In addition, plastic substrates such as polyimide, polyethylene napthalate (PEN), and polyethylene terephthalate (PET) may be used as the opaque substrate.

The photovoltaic layer 200 includes a first electrode, a photoactive layer, and a second electrode.

The first electrode is an electrode stacked on the substrate 100 and is a transparent electrode such as zinc oxide (ZnO), tin oxide (SnO 2 ), or indium tin oxide (ITO), or silver (Ag), aluminum (Al), or copper. It may be a metal electrode such as (Cu), platinum (Pt), lead (Pd), or gold (Au).

The photoactive layer can include any material that converts incident light energy into electrical energy. For example, the photoactive layer may include a photoelectric conversion material capable of forming a thin film solar module such as amorphous silicon based, compound based, organic based and dye-sensitized solar cells. CIGS (CuInGaSe 2 ), CdTe, CIS (CuInSe 2 ), CZTS (Cu 2 ZnSnS 4 ) may be used as the compound family.

In addition, the photoactive layer may include a plurality of unit cell layers as well as a single unit cell layer. For example, the photoactive layer may include two unit cell layers stacked or three unit cell layers. Each of the stacked unit cell layers is a basic unit layer for performing photoelectric conversion.

An intermediate reflecting film may be inserted between the stacked unit cell layers to maximize internal light reflection effect. For example, when the photoactive layer includes two unit cell layers, an intermediate reflective film may be inserted between the two unit cell layers. Since the intermediate reflector is positioned between two unit cell layers, the incident light may partially reflect and partially transmit incident light. The intermediate reflector may be silicon carbide (SiC), silicon nitride (SiN), or titanium dioxide (TiO 2). ), ZnO (zinc oxide), ITO (indium tin oxide), SiO (silicon oxide), SnO 2 (tin oxide).

The second electrode is an electrode stacked on the photoactive layer and may be a transparent electrode such as zinc oxide (ZnO), tin oxide (SnO 2 ), or indium tin oxide (ITO).

Next, the first encapsulant 300 stacked on the photovoltaic layer 200 encapsulates the photovoltaic layer 200.

The first encapsulant 300 is formed on the second electrode to protect the photovoltaic layer 200. The first encapsulant 300 may be made of a light transmitting material. In addition, the first encapsulant 300 may be made of an insulating material. As the first encapsulant 300, an ethylene vinyl acetate (EVA), a poly vinyl butyral (PVB), an acrylic resin, a polyolefin (PO), a UV curing agent, or the like may be used.

The front sheet 400 stacked on the first encapsulant 300 to receive sunlight protects the upper surface to which the sunlight hits. The front sheet 400 should have good permeability, heat resistance, weather resistance, and the like. The front sheet 400 according to the embodiment may be made of FEP resin.

The second encapsulant 500 for protecting the flexible substrate 100 is positioned on the rear surface of the flexible substrate 100. The material of the second encapsulation material 500 may be made of the same material as the first encapsulation material 300.

The front sheet 400 may include surface irregularities to prevent reflection of incident light and to scatter the transmitted light to increase a light trapping effect. The pitch of the surface irregularities may be greater than or equal to 100 nm and less than or equal to 2 μm. When the pitch is 100 nm or more and 2 μm or less, scattering is possible in the visible light region and the infrared region. If the pitch is smaller than 100 nm, the scatterable wavelength is so short that scattering of incident light in the visible and infrared regions is impossible. If the pitch is larger than 2 μm, only infrared rays in the long wavelength region having a low contribution to photoelectric conversion can be scattered and thus have no effect. In addition, when the substrate 100 is a substrate including a FEP resin, the substrate 100 may include surface irregularities, and the pitch of the surface irregularities may be 100 nm or more and 2 μm or less.

The back sheet 600 serves to waterproof, insulate, and block ultraviolet rays of the photovoltaic layer 200. In addition, the back sheet 600 should be made of a material that can withstand high temperatures and humidity in order to extend the life of the solar module. The back sheet 600 according to the embodiment may be made of FEP resin. In addition, the back sheet 600 may also have surface irregularities having a pitch of 100 nm or more and 2 μm or less, thereby increasing the light confinement effect.

The FEP resin has a high transmittance of 90% or more and 98% or less for light having a wavelength of 400 nm or more and 1100 nm or less.

Therefore, in the embodiment, when the front sheet 400 and the back sheet 600 are made of a transparent FEP resin and the substrate 100 is transparent, a see-through type solar module may be made.

2 is a plan view from above of a thin film solar module according to an embodiment of the present invention.

Edge isolation may be performed at the edge of the photovoltaic module to manufacture the thin film photovoltaic module for electrical stability of the module. At this time, through the edge isolation, an invalid region 800 having a predetermined width is formed on the edge of the solar module. The invalid area 800 formed along the edge of the solar module surrounds the effective area 700 therein. The effective area 700 refers to an area in which solar cells are integrated to perform photoelectric conversion in preparation for the invalid area 800 in which photoelectric conversion cannot be performed. At this time, the distance from the edge of the photovoltaic module to the effective area should have a constant interval for the electrical stability of the thin film photovoltaic module. Therefore, in the effective area 700 of the thin film solar module, the distance d spaced from each side of the module should be 1 cm or more and 3 cm or less. When the spaced distance d is more than 1 cm, the electrical stability of the thin film solar module can be ensured, and when d is less than or equal to 3 cm, the effective 700 area of the thin film solar module is excessively reduced and the output is reduced. It can prevent.

In the thin film solar module according to the first embodiment, the thickness of the front sheet 400 or the back sheet 600 including the FEP resin may be 30 μm or more and 200 μm or less. If the thickness is thinner than 30 μm, moisture resistance and weather resistance are weakened. If the thickness is thicker than 200 μm, the permeability is lowered and the manufacturing cost is increased.

3 is a cross-sectional view of a thin film solar module including a dielectric film according to a first embodiment of the present invention.

Referring to FIG. 3, the front sheet 400 may include a dielectric film 350 in which metallic nanoparticles 350a capable of reflecting light are arranged. The metallic nanoparticles 350a may cause surface plasmonic resonance when light is incident to enhance the intensity of light. The metallic nanoparticles 350a may enhance light intensity by surface plasmon resonance. That is, the light of the long wavelength region of 800 nm or more is amplified by the strengthening of the electromagnetic field around the metallic nanoparticles 350a by the surface plasmon of the metallic nanoparticles 350a. Since the metallic nanoparticles 350a scatter some of the incident light, the metallic nanoparticles 350a may increase current generation by increasing the light trapping effect.

In addition, in a solar cell having a double junction structure or more, light in a short wavelength region is mainly absorbed by a unit cell in which light is incident first, and light in a long wavelength region is mainly absorbed in a unit cell in which light is incident later. Therefore, since the metallic nanoparticles 350a enhance the intensity of light in the long wavelength region, generation of current may be increased even if the intrinsic semiconductor layer of the unit cell to which light is incident is not thick.

The size of the metallic nanoparticles 350a may be 5 nm or more and 100 nm or less to enhance the intensity of light in the long wavelength region of 800 nm or more to cause surface plasmon resonance.

The dielectric film 350 is formed on the front sheet 400 by vacuum deposition, and the metallic nanoparticles 350a are arranged on the dielectric film 350, and then another dielectric film is deposited on the metallic nanoparticles 350a by vacuum deposition. It can be formed to cover. Accordingly, the metallic nanoparticles 350a may be stably arranged in the dielectric film 350.

The thickness of the dielectric film 350 may be 30 nm or more and 1000 nm or less. The thickness of the dielectric film 350 may be 30 nm or more in order to achieve refractive index matching between the front sheet 400 to which light is incident first and the first unit cell. In addition, when the thickness of the dielectric film 350 is 1000 nm or less, excessive absorption of light by the dielectric film 350 is prevented.

The metallic nanoparticles 350a may include at least one of gold, silver, aluminum, nickel, chromium, titanium, tin, zinc, platinum, and copper. In addition, the dielectric film 350 may include silica (SiO 2 ), titanium dioxide (TiO 2 ), aluminum oxide (Al 2 O 3 ), or the like.

In addition, as shown in FIG. 3, the back sheet 600 may also include a dielectric film 550 in which metallic nanoparticles 550a capable of reflecting light are arranged. That is, the generation of the current may be increased by using the metallic nanoparticles 550a.
