Bell Telephone Laboratories, which developed the silicon solar cell in 1954, has made available for high‐school use a solar‐energy experiments kit which contains the necessary materials for constructing an energy‐conversion cell. An accompanying booklet gives instructions on the cell’s preparation and the measurement of its performance and describes the underlying principles of the cell and three experiments that can be performed with it. The kits can be obtained by qualified high‐school science teachers, without charge, from any local Bell Telephone office.
