Journal ArticleDOI
Improving thin-film crystalline silicon solar cell efficiencies with photonic crystals
TL;DR: Here, a photonic crystal-based light-trapping approach is analyzed and compared to previous approaches for c-Si thin film solar cells, which gives rise to weak absorption of one-third of usable solar photons.
Journal ArticleDOI
Design of Highly Efficient Light-Trapping Structures for Thin-Film Crystalline Silicon Solar Cells
Ning-Ning Feng,Jurgen Michel,Lirong Zeng,Jifeng Liu,Ching-yin Hong,Lionel C. Kimerling,Xiaoman Duan +6 more
TL;DR: In this paper, a light-trapping structure was proposed to increase the efficiency of thin-film crystalline silicon solar cells, which consists of an antireflection (AR) coating, a silicon active layer, and a back reflector that combines a diffractive reflection grating with a distributed Bragg reflector.
PatentDOI
Light trapping in thin film solar cells using textured photonic crystal
TL;DR: In this article, a photonic crystal is coupled with a distributed Bragg reflector (DBR) for trapping the light in a solar cell, where the DBR is used to generate the light.
Journal ArticleDOI
New Solar Cells with Novel Light Trapping via Textured Photonic Crystal Back Reflector
Lirong Zeng,Yasha Yi,Ching-yin Hong,Bernard A. Alamariu,Jifeng Liu,Xiaoman Duan,Lionel C. Kimerling +6 more
TL;DR: In this article, a light-trapping scheme for solar cells that can enhance the optical path length by more than 104 times using a textured photonic crystal structure as a backside reflector was developed.
Journal ArticleDOI
Optimization of Textured Photonic Crystal Backside Reflector for Si Thin Film Solar Cells
Lirong Zeng,Peter Bermel,Yasha Yi,Ning Ning Feng,Bernard A. Alamariu,Ching-yin Hong,Xiaoman Duan,John D. Joannopoulos,Lionel C. Kimerling +8 more
TL;DR: In this paper, a textured photonic crystal was introduced into Si thin film solar cells and the Scattering Matrix method was used to systematically optimize all the parameters of the two components of the backside reflector, grating and distributed Bragg reflector.
