Product Briefing Outline: HORIBA Jobin Yvon has
introduced the MM-16, a spectroscopic ellipsometer dedicated to the
advanced characterization of film thickness and optical constants for a
broad range of materials such as semiconductors, compounds, alloys and
organic thin films.

Problem: Spectroscopic ellipsometers allow the
accurate characterization of a range of properties including the layer
thickness, optical constants, composition, crystallinity, anisotropy,
and uniformity. Thickness determinations ranging from a few angstroms
to tens of microns are possible for single layers and complex
multilayer stacks.

Solution: The MM-16 has a
simple optical configuration using liquid crystals (LCs) as polarizer.
Each ellipsometer head contains two LC modulators, each modulator
having two possible polarisation states. The MM-16 is unique in its
ability to collect full spectral ellipsometric data at high resolution
and calculate the complete 16-element Mueller Matrix in <2 seconds.
This allows simple characterization of complex birefringent materials,
and also simplifies the investigation of samples exhibiting
depolarization effects. These unique capabilities fulfil the
requirements for standard thin film metrology as well as many emerging
applications using complex materials and structures in the display,
biotechnology, packaging and semiconductor areas.

Applications:
Characterization of thin films deposited on transparent substrates such
as those found in OLED, solar cell, or photovoltaic cells. It can also
be used for dielectric film, metals, resist and polymer
characterization.

Platform: The MM-16 is
controlled from the DeltaPsi2 integrated software package to provide
turnkey operation for a wide range of industrial and research
applications.

Availability: July 2006 onwards.

The utility-scale PV market is poised for exponential growth and yet the industry still has many fundamental opportunities to improve on standards and best practice. Tracker shade loss has been one of those topics that deserve more attention, but has been typically handled by derate factors rather than trying to accurately forecast the loss over the life of the system. Join Nextracker’s subject matter experts, Aron Dobos and Neelesh Umachandran, and Rounak Kharait, director of solar energy assessments at DNV, for a webinar about why shade modeling matters and recommendations on what the solar industry should do about it.

Join us to hear directly from the CTOs and heads-of-research from the top-20 cell/wafer producers to the PV industry today. The event will focus on predicting the key metrics underpinning the next big shift to n-type with answers to the key questions: When will the transition to n-type happen? Which companies will be first to 10 GW capacity and production? Who will be the key equipment suppliers for the new production lines? Which n-type process flow/architecture will emerge as the front-runner? What will polysilicon purity and wafer thickness levels look like for optimized n-type manufacturing? What will the upstream poly/wafer supply-chain look like in 5 years from now?
