Technology Application

* Photovolatic cells * c-Si PV cells

Detailed Technology Description

A PV cell that incorporates this invention can function more efficiently by laterally transporting the heat along the planar heat sink. The module configuration is comprised of two unique layers. The insulating layer consists of a very thin film of electrically insulating material, located between the PV cell substrate and the lower layers. This is followed by the planar heat sink layer, made of thermally conducting material such as graphene or aluminum. Channels or tubes, which can be economically fabricated, are incorporated across a full dimension, lengthwise or by width, of the module. This arrangement allows ambient air to flow through the channels while absorbing heat from the channel wall. Due to the typical mounting angle of PV modules, these tubes or channels convectively carry the heat out of the end of the channels.
