研究目的
Investigating the viability of Cu(In,Ga)Se2 thin-film solar cells for space applications, focusing on emissivity and buffer layers to improve efficiency under harsh space conditions.
研究成果
High-emissivity coatings can significantly reduce the operational temperature of Cu(In,Ga)Se2 solar cells, thereby improving efficiency. ZnS buffer layers, with their high energy band gap, show promise for reducing spectral absorption losses and enhancing current density, making them a viable alternative to CdS buffers in space applications.
研究不足
The study is a meta-analysis relying on existing literature, which may limit the scope of experimental data available. The approach to calculating the effect of emissivity on temperature is an approximation, as absorptivity is considered constant for practical purposes.
