Embodiment 1

[0075] Example 1 : Manufactured with Cu-containing 2 Photovoltaic cells with hole carrier layer of O nanoparticles and ELVACITE polymer

[0076] Photovoltaic cells with hole carrier layers containing PEDOT (as a control) or Cu 2 Combination of O nanoparticles with ELVACITE polymer:

[0077] The indium-tin-oxide coated plastic substrate was cut into 2"x2" squares and structured into conductive electrode strips. Clean the substrate by sonicating in isopropanol (IPA) for 10 min. The substrate was then dried using an air gun and coated with a titanium alkoxide sol containing 0.1M titanium tetrabutoxide in isopropanol using knife coating at 80°C. The titanium alkoxide film was then dried at 80° C. for 2 minutes and annealed at 120° C. for 10 minutes to form a TiOx layer as a hole blocking layer. The photoactive layer was formed by knife coating a 2.5% solution containing electron donor material and electron acceptor material in a 1:1 weight ratio in o-xylene on the TiOx layer...

Embodiment 2

[0083] Example 2: Manufactured with Cu 2 Photovoltaic cells with O nanoparticles without polymers or hole-carrier layers with different types of polymers

[0084] Four types of photovoltaic cells were prepared according to the procedure described in Example 1: Photovoltaic cell (1) included a hole carrier layer containing PEDOT / PSS as a control. The photovoltaic cell (2) includes a hole carrier layer made of only 0.5wt% Cu contained in IPA 2 A dispersion of O nanoparticles (ie without any polymer) was prepared. The photovoltaic cell (3) includes a hole carrier layer made of 2.0 wt% Cu contained in methoxypropanol 2 A dispersion of O nanoparticles and 0.2wt% ELVACITE polymer was prepared. The photovoltaic cell (4) includes a hole carrier layer made of 2.0 wt% Cu contained in methoxypropanol 2 A dispersion of O nanoparticles and 0.33wt% NAFION polymer was prepared. All types of photovoltaic cells were prepared at blade temperature of 65°C and 80°C.

Embodiment 3

[0090] Example 3 : Contains Cu 2 Hole carrier layers of O nanoparticles and various polymer binders

[0091] Preparation of coatings useful as hole carrier layers by using dispersions containing Cu alone 2 O nanoparticles or Cu in a weight ratio of 20 / 3 in butanol in the presence of the following binders 2 O nanoparticles: (1) Disperbyk-190, available from BYK-Chemie GmbH (Wesel, Germany), (2) Solplus D540, available from Lubrizol Advanced Materials (Cleveland, Ohio), (3) manufactured by AB111446 (the full Fluorooctyltriethoxysilane, available from ABCR GmbH & Co. KG, Karlsruhe, Germany), and (4) Zusoplast 9002 (ie polyethylene glycol 200, available from Zschimmer & Schwarz, Lahnstein, Germany). The thickness, conductivity, and work function of the dried coatings were measured and summarized in Table 3.

[0092] table 3

[0093] sample

[0094] The results show that samples (V) and (VII) exhibit a work function similar to that of P3HT (ie about -5 eV).

Description

[0001] Cross References to Related Applications [0002] Pursuant to 35 U.S.C. §119(e), this application claims priority to U.S. Provisional Application Serial No. 61 / 439,122, filed February 3, 2011, the contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to photovoltaic cells, and related components, systems, and methods. Background technique [0004] Photovoltaic cells are commonly used to convert energy in the form of light into energy in the form of electricity. A typical photovoltaic cell includes a photoactive material placed between two electrodes. Typically, light passes through one or both of the electrodes to interact with the photoactive material. As a result, the ability of one or both electrodes to transmit light (eg, light at one or more wavelengths absorbed by the photoactive material) can limit the overall efficiency of the photovoltaic cell. In many photovoltaic cells, films of semiconducting mat...
