Abstract

The invention discloses a reflective PETE solar photoelectric conversion method and a conversion device thereof, A material of the cathode and the anode are placed in a vacuum environment, the sunlight is directly irradiated on the front of the cathode material after the sunlight is condensed by the condensing device, the cathode material absorbs the condensed sunlight to generate a large number of hot electrons, and the hot electrons are emitted into a vacuum and then are collected by the anode material to form a photocurrent; Based on the reflective PETE solar photovoltaic conversion method,a reflective PETE solar photovoltaic conversion device is designed according to the reflective PETE solar photovoltaic conversion method. A large number of hot electrons can be generated by absorbingand converging sunlight with an InN nanowire cathode, The photoelectric current is generated after the hot electrons are emitted into the vacuum and then collected by the anode, which avoids the complex bonding process of the transmission cathode, and at the same time, the textured nanostructure can be prepared on the surface of the cathode, the absorption of sunlight by the cathode is increased,and the photoelectric conversion efficiency is effectively improved.

Description

Technical field [0001] The invention relates to the technical field of solar power generation, in particular to a reflective PETE solar photoelectric conversion method and a conversion device thereof. Background technique [0002] With the global warming, environmental pollution and energy shortage intensified, photovoltaic power generation has received unprecedented attention, especially in recent years. However, to realize the large-scale application of photovoltaic power generation and become an important part of human energy structure, it is necessary to continuously propose new solar photovoltaic conversion methods and adopt new materials to improve the conversion efficiency of solar cells and reduce their production costs. [0003] For traditional pn junction solar cells, the energy conversion loss process generally includes: 1. Transmission loss caused by the inability to absorb low-energy photons with energy less than the band gap; 2. Lattice heating loss; 3. pn Knot loss;...
