TASK 10 - SOLAR MATERIALS R&D
DURATION: 1985 - 1991
OPERATING AGENT: Japan
- Performance criteria for new materials
- Service life prediction methods
- Understanding thermal and optical properties of solar
Participants in Task 10 evaluated the energy benefits
of a number of new materials for solar applications and their impact on
system o component performance. Tnis included identification of the properties
required of materials in order to increase system or subsystem efficiency.
A veriew of failure and degradation modes in selected solar materials
was also prepared.
Another activity centered around the round-robin testing
of standardized collector absorbers for optical properties. The micro-climate
characteristics of the absorber surface, the effects of controlled stresses
(temperature, moisture, humidity, pollutants and irradiation) on the absorber
properties were studied. Models for predicting the service life of these
and other materials were evaluated.
Another study focused on materials used for certain
high performance glazings. Task researchers characterized the optical,
thermal, and electrical properties as well as durability of electrochromic
optical devices, low-emmittance films, and transparent insulation materials.
Task 18, Advanced Glazing Materials, was initiated as a follow-up to this
