What is a HJT solar cell?
HJT is the acronym for hetero-junction solar cells. Introduced by Japanese company Sanyo in the 1980s, then acquired by Panasonic in 2010s, HJT is considered as a potential successor to the popular PERC solar cell as of the time of…
What is a TOPCON solar cell?
TOPCON (also known as passivated contact) solar cell, is touted as the next generation of solar cell technology after PERC. This novel architecture is introduced by researchers at Fraunhofer Institute for Solar Energy Systems in Germany in 2013 [1]. Compared…
Predicting Solar Cell Efficiency with Machine Learning – Part 2 -Regularization
In part 1, ANN and linear regression models were built with Tensorflow and Keras to predict the efficiency of crystalline Si solar cells when the thickness of front silicon nitride anti-reflection layer changes. As also discussed in part 1, the…
Silicon nitride density estimation with FTIR, Ellipsometry and BHF
Silicon nitride (SiNx) is a dielectric material that is widely used as passivation layers, electrical isolation layers, as well as etch and diffusion masks for semiconductor devices. The density of SiNx layer may influence its effectiveness in achieving these roles….
Predicting Solar Cell Efficiency with Machine Learning – Part 1
Machine learning (ML) has been the hot buzzwords for many applications, from speech recognition, search engines optimization to self-driving vehicles. After completing several online ML courses, particularly Andrew Ng’s Machine Learning and Deep Learning specializations, I wonder if I could…
