Problems solved by technology

Second-generation batteries rely on thin-film technologies and materials that have been developed to reduce the involved costs, but have reduced efficiencies due to inherent drawbacks of low-quality processing methods
The toxicity of these systems and their use of expensive rare earth metals has prevented them from entering the market in large quantities

Embodiment Construction

[0062] The invention will now be illustrated in the following non-limiting examples.

[0063] Devices were fabricated as follows, at 50 °C in H 2 O, HCl and HNO 3 ITO-coated glass substrates (PGO, CEC005, 2 , ≤2ppmH 2 0) The substrate was dried overnight at ambient temperature. Transfer the substrate into a vacuum chamber where the 2.5 x 10 -7 The following substances are deposited at a base pressure of Torr:

[0064] Indium at 1.5-10nm, followed by lead at 120nm.

[0065] 2.120nm lead, followed by 5-10nm antimony.

[0066] Afterwards, the film was placed on a hot plate outside the glove box and annealed at 350° C. for one hour, during which time the film changed from glowing black to opaque tan. Each device has a 3mm 2 area. Afterwards, the substrate was transferred to a vacuum chamber, where the 2.5×10 -7 Al electrodes (70 nm) were deposited under Torr pressure. figure 1 The device geometry is shown.

[0067] Scanning electron microscopy was performed on a JEOL J...

Abstract

The present invention provides a solar cell comprising an anode and a cathode with a photosensitive layer therebetween, wherein the photosensitive layer is at most 1000 nm thick and comprises crystalline lead oxide as a photosensitive material, wherein the lead oxide is doped with antimony and / or indium.

Description

technical field [0001] The present invention relates to the field of photovoltaic materials, more particularly to solar cells, methods for manufacturing solar cells and methods for reusing solar cells. Background technique [0002] Modern solar cells can be classified into one of three generations. First-generation cells consisted of expensive, energy-intensive (during production), large-area, high-quality single-junction devices. Second-generation cells rely on thin-film technologies and materials that have been developed to reduce the involved costs, but have reduced efficiencies due to inherent drawbacks of low-quality processing methods. The purpose of the third generation technology is to provide enhanced performance while maintaining very low production costs. [0003] The main second-generation thin-film solar cells include copper indium gallium diselenide (CIGS-CIS) and cadmium telluride. US5464939 discloses one such thin film solar cell. The toxicity of these sy...
