摘要

为了开发一种基于cd /CdTe系统的柔性高效薄膜太阳能电池的建设性解决方案，该解决方案适用于将太阳能电池直接安装到标准太阳能热集热器板上的太阳能电池，制造了具有不同厚度功能层的柔性太阳能电池样品系列。太阳能电池测试样品的研究是通过光学方法进行的，并通过测量和随后的分析处理的照明电流电压特性。柔性CdS/CdTe基太阳能电池在可见光范围内的吸收系数为105 cm-1，在红外光谱区域的反射系数不超过7- 8%，这使得具有选择性涂层的吸收剂可以从集热器中排除，因为它的功能将直接由这种太阳能电池发挥。研究表明，由于柔性太阳能电池的衬底重量显著减少，有可能实现高达2.0 kW/kg的特定功率值。

Influence of Functional Layers Thickness on CdTe Based Flexible Solar Cells Efficiency

In order to develop a constructive solution of flexible high efficiency thin-film solar cells based on the CdS/CdTe system adapted for the installation of a solar battery from such solar cells directly onto the standard solar thermal collector plate the serie of flexible solar cel cells samples with various thickness of functional layers it has been manufactured. The research of solar cells test samples carried out by optical methods and by measurement and subsequent analytical processing of illuminated current-voltage characteristics. It has been established that the absorption coefficient of flexible CdS/CdTe based solar cells in the visible range is 105 cm-1, and the reflection coefficient in the infrared spectrum region does not exceed 7-8 % which allows excluding absorber with a selective coating from collector because its function will perform directly by such solar cell. It has been shown that, due to a significant reduction of substrate weight for flexible solar cells, it was possible to achieve specific power values up to 2.0 kW/kg.
