Abstract

The invention is a highly-efficient solar cell, relates to a photocell. The highly-efficient solar cell according to the invention has a substrate made of insulation materials and a panel made of photoelectric conversion materials; outside surface of the panel is provided with transparent spectrum conversion thin layer containing rare-earth fluorescent materials which is activated by corresponded weak solar spectrum band of the photoelectric conversion materials, strong solar spectrum band of the photoelectric conversion materials is emitted. Sunlight is used to activate the rare-earth fluorescent materials to generate a fluorescence effect, spectrums with better response to the solar cell is obtained by converting more solar spectrums with simple structure and low cost, and then photoelectric transformation efficiency of the solar cell is increased. Problem in improvement of photoelectric transformation efficiency by using solar spectrums with complex structure and high cost of the solar cell is solved.

Description

technical field [0001] The invention relates to a photovoltaic cell. Background technique [0002] A solar cell has a substrate made of insulating materials and a panel made of photoelectric conversion materials. It is a semiconductor device that uses the photovoltaic effect of photoelectric conversion materials to directly convert solar energy into electrical energy. It is easy to realize grid-connected power generation or as an independent energy source. As we all know, solar cell power generation has many advantages, such as safety and reliability, no noise, no pollution, energy available everywhere, no need to consume fuel, no mechanical rotating parts, low failure rate, easy maintenance, unattended, random size, and Conveniently combined with buildings, etc., these advantages are beyond the reach of conventional power generation. [0003] comparative observation image 3 The solar spectrum curve at 1:30 p.m., Figure 7 The spectral response curve of the monocrystallin...
