Window material for silicon based thin film solar battery and preparing method thereof

Abstract

The present invention discloses windows material for silicone base thin film solar battery and manufacture method thereof. The windows material is phosphorus with silicone base thin film N, which includes phosphorus with N type micro crystal silica thin film, or phosphorus with N type nano silica. The preparing of the windows material is that put the sample to be processed in the deposition system, the deposition is taken as the phosphorus doped silicon base thin film N of the windows material for silicone base thin film solar cell on the intrinsic silicone base thin film I of the sample to be processed or the transparent conductive film T1. The present invention provides a windows layer material for the novel silicone base thin film solar cell novel silicone base thin film solar cell uses micro crystal silicone base or nano silicone base thin film material electric and hole mobility with the characteristic of same magnitude, provides a windows layer material for a novel silicone base thin film solar cell, producing the P / I / N type thin film solar cell on non-transparent or transparent substrate, can also produce N / I / P type thin film solar cell on the transparent substrate, the technique boost flexibly and obtain good battery efficiency more easily.

Description

【Technical field】 [0001] The invention relates to the field of thin-film solar cells, in particular to a window material for silicon-based thin-film solar cells and a preparation method thereof. 【Background technique】 [0002] Solar cells convert solar energy directly into electricity. Large-scale photovoltaic power generation can solve the energy problems of residents in the vast central and western regions of my country without electricity in the near future, and make these areas get out of the energy dilemma. In the long run, to make photovoltaic power generation truly an important part of the future energy system, the key is to achieve its performance / price ratio comparable to conventional energy. According to the basic national conditions of our country, in order to realize the future goal of solar cells serving the national economy, reducing the cost of solar cells and realizing the thin film of solar cells has been set as the main direction for the development of sol...

AI Technical Summary

Problems solved by technology

For thin-film solar cells applied to flexible substrates, flexible substrates such as stainless steel or plastic substrates (polyimide) are opaque materials. In order to allow light to enter from the P layer, the structure of the cell needs to be N / I / P, In this way, the relatively mature deposition process corresponding to the preparation of P / I / N structure solar cells on glass substrates will not be well transferred to flexible substrate solar cells.
