Optical transmittance assessment method and device and photovoltaic chip packaging design method

Abstract

The invention discloses an optical transmittance assessment method and device and a photovoltaic chip packaging design method, and the method comprises the steps: obtaining the packaging parameters ofa to-be-assessed photovoltaic chip packaging combination; according to a pre-constructed optical transmittance assessment model and the packaging parameters of the packaging combination, assessing the optical transmittance of the packaging combination in the absorption spectrum section of the photovoltaic chip; wherein the packaging parameters of the packaging combination comprise the material ofeach packaging layer in the packaging combination and the thickness of each packaging layer in the packaging combination. Through the scheme of the invention, the assessment of the optical transmittance of the packaging combination in the absorption spectrum section of the photovoltaic chip can be simply and conveniently realized, and a basis can be provided for finding an appropriate packaging combination in the initial design stage, so that the research and development test cost and the research and development period of a photovoltaic product are reduced.

Description

Technical field [0001] The present invention relates to the technical field of solar cells, in particular to an optical transmittance evaluation method, device and photovoltaic chip packaging design method. Background technique [0002] Solar cell, also known as "solar chip" or "photovoltaic chip", is a kind of optoelectronic semiconductor sheet that directly converts light energy into electrical energy through photoelectric effect or photochemical effect; the photovoltaic chip is packaged by various materials, which can be applied to Solar photovoltaic modules in various occasions. [0003] Crystalline silicon solar power technology and thin film solar power technology are the core technologies of solar cells. Thin-film photovoltaic modules are international emerging technologies. Thin-film photovoltaic modules have the characteristics of thin thickness and light weight that are different from crystalline silicon photovoltaic modules. The current optical transmittance evaluation...

Problems solved by technology

However, the development and testing costs of this method are relatively high

[0004] Moreover, since the light transmittance design of lamination and packaging materials of crystalline silicon photovoltaic modules is relatively fixed and mature, thin-film photovoltaic modules and supporting packaging materials are relatively new. Experimental testing method, the cost of R&D testing is higher
