    摘要: A photovoltaic cell includes a photoelectric conversion element (PCE) in which an i-type silicon layer formed of a microcrystalline silicon film is provided between an n-type silicon layer and a p-type silicon layer, and the n-type silicon layer or p-type silicon layer positioned on a substrate side is configured of an amorphous silicon film. The PCE is formed wherein a mixture of a silane containing gas and hydrogen gas is introduced into a chamber and a seed layer formed of a microcrystalline silicon film is formed between the n-type silicon layer or p-type silicon layer positioned on the substrate side and the i-type silicon layer. The crystallization rate of a portion in contact with the n-type silicon layer or p-type silicon layer positioned on the substrate side is lower than that of the i-type silicon layer, and the rate increases continuously, or gradually in two or more stages, toward the i-type silicon layer side, continuing to the i-type silicon layer.

    摘要: A photovoltaic (solar) cell comprises two photovoltaic devices that are quantum mechanically coupled via a charge-coupling layer. One of the PV devices may have an energy band gap that is larger than or equal to an energy band gap of the other of the PV devices. The effective electron barrier heights or electron affinity on side portions of the quantum coupling layer are higher than the maximum energy of photo-generated electrons in the photovoltaic devices. The photovoltaic device with larger band gap may include an electron and/or hole transport layer and photon absorbing layer. Photons are transmitted through the transport layer to the absorbing layer. Some high energy photons are absorbed by the absorbing layer. The absorbing layer may function as an absorber of high energy photons and generator of electrons/holes (or excitons). Holes generated in the absorbing layer may be quenched by electrons from the second photovoltaic device.

    摘要: The absorption coefficient of silicon for infrared light is very low and most solar cells absorb very little of the infrared light energy in sunlight. Very thick cells of crystalline silicon can be used to increase the absorption of infrared light energy but the cost of thick crystalline cells is prohibitive. The present invention relates to the use of less expensive microcrystalline silicon solar cells and the use of backside texturing with diffusive scattering to give a very large increase in the absorption of infrared light. Backside texturing with diffusive scattering and with a smooth front surface of the solar cell results in multiple internal reflections, light trapping, and a large enhancement of the absorption of infrared solar energy.
