Solar cell module

An improved solar cell module for use in terrestrial environments is disclosed. It is characterized by: (1) an internally reflective plate having a planar surface of incidence and an opposed textured surface (2) a plurality of uniformly spaced silicon solar cells having the active surfaces thereof bonded to portions of the textured surface, and (3) a layer of diffusely reflective matter applied to the textured surface in surrounding relation with the solar cells for reflecting solar energy. The solar energy then strikes the surface of incidence at such angles as to be internally re-reflected and caused to progress toward the active surfaces of the solar cells, whereby concentration of incident flux on the solar cell is achieved without increased module depth

Reciprocal Altruism as a Felony: Antitrust and the Prisoner\u27s Dilemma

This essay is about the idea of cooperation in antitrust law. At the outset, ·I clarify my terminology. Biologists often refer to reciprocal altruism. Reciprocal altruism in the antitrust context has an odd semantic ring. There is nothing altruistic or self-sacrificing about the cooperation that antitrust rules outlaw: cartel price fixing. Firms do it strictly for the money. I prefer the term reciprocity to describe a firm\u27s strategy to pursue behavior that will profit it only if competing firms engage in similar behavior. This usage can create confusion in the present context, however, because reciprocity is also an antitrust term of art that refers to one firm\u27s decision to sell to another only if the second agrees in turn to buy from the first. In this Article I use reciprocity in the former sense rather than in its latter, antitrust sense
