content: Solar cells come in many shapes and sizes, and are manufactured with a variety of materials. The wafer of these rectangular cells is made with the element silicon. The dark areas convert sunlight into electricity while the lines are part of the electrical circuit. The cells were made by Hoffman Electronics in the early 1960s. One has an lightning bolt in the center, another an "HLH" logo connected by a crossbar. HLH were the initials of company founder Herman Leslie Hoffman. The logos are part of the electrical circuit and also intended to advertise the product.
