The author describes the results of experiments where small samples of cellulose are submitted to short flashes of concentrated solar radiation. Also it shows the optical properties of cellulose with respect to the efficiency of sunlight absorption. The aim of the first part of paper is to briefly describe the different solar chemical reactions being studied in the world presently. The second part tells that concentrated radiation can also be used to study the basic biomass thermal degradation. Concentrated solar energy can be used to drive the thermochemical processes. Many types of chemical systems can be considered for the production of chemical energy carriers. The solar thermochemical conversion of carbonaceous feedstock is the one of the most suggested option. Concentrated radiations can be used to drive endothermic reactions under controllable and clean conditions of high heat flux densities. Biomass is a carbonaceous material. So special emphasis is given on biomass conversion using solar energy.
