  • Patent number: 10644188
    Abstract: An epitaxially grown III-V layer is separated from the growth substrate. The III-V layer can be an inverted lattice matched (ILM) or inverted metamorphic (IMM) solar cell, or a light emitting diode (LED). A sacrificial epitaxial layer is embedded between the GaAs wafer and the III-V layer. The sacrificial layer is damaged by absorbing IR laser radiation. A Nd:YAG laser is chosen with the right wavelength, pulse width and power. The radiation is not absorbed by either the GaAs wafer or the III-V layer. No expensive ion implantation or lateral chemical etching of a sacrificial layer is needed. The III-V layer is detached from the growth wafer by propagating a crack through the damaged layer. The active layer is transferred wafer-scale to inexpensive, flexible, organic substrate. The process allows re-using of the wafer to grow new III-V layers, resulting in savings in raw materials and grinding and etching costs.

  • Patent number: 10629763
    Abstract: A solar cell module includes: two solar cells adjacent one another across a space; an elongated light reflector extending over the two solar cells; and a front protector covering front surfaces of the two solar cells and the light reflector. In a plan view of the two solar cells, each of the two solar cells has chamfered corners and a substantially octagonal shape with linear long sides and linear or non-linear short sides, connected alternately. The light reflector, in the plan view, protrudes in the longitudinal direction from an intersection between a first long side facing another long side across the space, among the long sides, and a first short side one end of which is connected to the first long side, among the short sides, to cause light reflected by the uneven structure of the light-reflective film to reach at least one of the two solar cells.

  • Patent number: 10622161
    Abstract: Photoelectronic devices using perovskite single-crystal materials having a narrow spectral response, e.g., with a full-width-at-half-maximum response of less than about 20 nm, are provided. The response spectra are continuously (in frequency band) settable or tunable, e.g., from blue to red, by changing the halide composition and thus the band gap of the single crystals. The narrow-band response can be explained by the strong surface charge recombination of the excess carriers close to the crystal surfaces generated by short wavelength light. The excess carriers generated by below-band gap excitation locate away from the surfaces and can be much more efficiently collected by the electrodes to produce a photocurrent.

    Abstract: Contact holes of solar cells are formed by laser ablation to accommodate various solar cell designs. Use of a laser to form the contact holes is facilitated by replacing films formed on the diffusion regions with a film that has substantially uniform thickness. Contact holes may be formed to deep diffusion regions to increase the laser ablation process margins. The laser configuration may be tailored to form contact holes through dielectric films of varying thicknesses.
